+<h2>Particle Decays</h2>
+
+The <code>ParticleDecays</code> class performs the sequential decays of
+all unstable hadrons produced in the string fragmentation stage,
+i.e. up to and including <i>b</i> hadrons and their decay products,
+such as the <i>tau</i> lepton. It is not to be used for the decay of
+more massive <?php $filepath = $_GET["filepath"];
+echo "<a href='ResonanceDecays.php?filepath=".$filepath."' target='page'>";?>resonances</a>, such as top,
+<i>Z^0</i> or SUSY, where decays must be performed already at the
+<code>ProcessLevel</code> of the event generation.
+
+<p/>
+The decay description essentially copies the one present in
+PYTHIA since many years, but with some improvements, e.g. in the decay
+tables and the number of decay models available. Recently a more
+sophisticated handling of <i>tau</i> decays has also been introduced.
+Some issues may need further polishing.
+
+<h3>Variables determining whether a particle decays</h3>
+
+Before a particle is actually decayed, a number of checks are made.
+
+<p/>
+(i) Decay modes must have been defined for the particle kind;
+tested by the <code>canDecay()</code> method of <code>Event</code>
+(and <code>ParticleData</code>).
+
+<p/>
+(ii) The main switch for allowing this particle kind to decay must
+be on; tested by the <code>mayDecay()</code> method of <code>Event</code>
+(and <code>ParticleData</code>).
+
+<p/>
+(iii) Particles may be requested to have a nominal proper lifetime
+<i>tau0</i> below a threshold.
+

+<input type="radio" name="1" value="off" checked="checked"><strong>Off</strong>
+ (<code>default = <strong>off</strong></code>)<br/>
+When on, only particles with <i>tau0 < tau0Max</i> are decayed.
+

+<br/><br/><table><tr><td><strong>ParticleDecays:tau0Max </td><td></td><td> <input type="text" name="2" value="10." size="20"/> (<code>default = <strong>10.</strong></code>; <code>minimum = 0.</code>)</td></tr></table>

+The above <i>tauMax</i>, expressed in mm/c.<br/>
+In order for this and the subsequent tests to work, a <i>tau</i>
+is selected and stored for each particle, whether in the end it
+decays or not. (If each test would use a different temporary
+<i>tau</i> it would lead to inconsistencies.)

+
+
+<h3>Tau decays</h3>
+
+A new machinery has been introduced to handle <i>tau</i> lepton decays,
+with helicity information related to the production process and with
+the form of the hadronic current fitted to data. It is largely based
+on the corresponding Herwig++ implementation [<a href="Bibliography.php" target="page">Gre07</a>], with
+some input from Tauola [<a href="Bibliography.php" target="page">Jad90</a>]. A complete writeup is
+in preparation [<a href="Bibliography.php" target="page">Ilt11</a>].
+
+<p/>
+For <i>tau</i>s in external processes, interfaced with Les Houches
+Acccord information available, e.g. via Les Houches Event Files (LHEF),
+the new machinery interprets the SPINUP number for <i>tau</i> leptons
+as giving their helicity, and decays them accordingly. The only exceptions
+are when a specific polarization is forced by the user (see below),
+which then overrides the SPINUP value, or when SPINUP has the special
+value 9 (unpolarized). In the latter case, PYTHIA defaults back to
+attempting to determine the helicity structure from the production
+process, in the same way as for internal processes.
+
+<p/>
+This new machinery is on by default, but it is possible to revert to
+the simpler old decay handling, e.g. to study differences. Furthermore
+the spin tracing framework does not yet cover all possibilities; notably
+it cannot handle taus coming from SUSY decay chains
+(except via LHEF), so it makes sense
+to switch off the new machinery in such instances, for speed reasons if
+nothing else. In case only one tau mother species is undefined, the
+polarization involved can be set by hand.

+to force a specific <ei>tau</ei> polarization, only affect the decay
+of the <ei>tau</ei>. The angular distribution of the <ei>tau</ei> itself,
+given by its production, is not modified by these options. If you want, e.g.,
+a righthanded <ei>W</ei>, or a SUSY decay chain, the kinematics should
+be handled by the corresponding cross section class(es), supplemented by
+the resonance decay one(s). The options here could then still be used
+to ensure the correct polarization at the <ei>tau</ei> decay stage.

+In semileptonic decays to more than one hadron, such as
+<i>B -> nu l D pi</i>, decay products after the first three are
+dampened in momentum by an explicit weight factor
+<i>exp(-p^2/sigmaSoft^2)</i>, where <i>p</i> is the
+three-momentum in the rest frame of the decaying particle.
+This takes into account that such further particles come from the
+fragmentation of the spectator parton and thus should be soft.
+
+
+<p/>
+When a decay mode is defined in terms of a partonic content, a random
+multiplicity (and a random flavour set) of hadrons is to be picked,
+especially for some charm and bottom decays. This is done according to
+a Poissonian distribution, for <i>n_p</i> normal particles and
+<i>n_q</i> quarks the average value is chosen as
+<br/><i>
+ n_p/ 2 + n_q/4 + multIncrease * ln ( mDiff / multRefMass)
+</i><br/>
+with <i>mDiff</i> the difference between the decaying particle mass
+and the sum of the normal-particle masses and the constituent quark masses.
+For gluonic systems <i>multGoffset</i> offers and optional additional
+term to the multiplicity. The lowest possible multiplicity is
+<i>n_p + n_q/2</i> (but at least 2) and the highest possible 10.
+If the picked hadrons have a summed mass above that of the mother a
+new try is made, including a new multiplicity. These constraints
+imply that the actual average multiplicity does not quite agree with
+the formula above.

+When a decay is given as a list of four partons to be turned into
+hadrons (primarily for modes 41 - 80) it is assumed that they are
+listed in pairs, as a first and a second colour singlet, which could
+give rise to separate sets of hadrons. Here <i>colRearrange</i> is
+the probability that this original assignment is not respected, and
+default corresponds to no memory of this original colour topology.

+or <i>gamma g g</i>, with <code>meMode > 90</code>, allow or not a
+shower to develop from it, before the partonic system is hadronized.
+(The typical example is <i>Upsilon</i> decay.)
+
+
+In addition, some variables defined for string fragmentation and for
+flavour production are used also here.
+
+<h3>Modes for Matrix Element Processing</h3>
+
+Some decays can be treated better than what pure phase space allows,
+by reweighting with appropriate matrix elements. In others a partonic
+content has to be converted to a set of hadrons. The presence of such
+corrections is signalled by a nonvanishing <code>meMode()</code> value
+for a decay mode in the <?php $filepath = $_GET["filepath"];
+echo "<a href='ParticleDataScheme.php?filepath=".$filepath."' target='page'>";?>particle
+data table</a>. The list of allowed possibilities almost agrees with the
+PYTHIA 6 ones, but several obsolete choices have been removed,
+a few new introduced, and most have been moved for better consistency.
+Here is the list of currently allowed <code>meMode()</code> codes:
+<ul>
+<li> 0 : pure phase space of produced particles ("default");
+input of partons is allowed and then the partonic content is
+converted into the minimal number of hadrons (i.e. one per
+parton pair, but at least two particles in total)</li>
+<li> 1 : <i>omega</i> and <i>phi -> pi+ pi- pi0</i></li>
+<li> 2 : polarization in <i>V -> PS + PS</i> (<i>V</i> = vector,
+<i>PS</i> = pseudoscalar), when <i>V</i> is produced by
+<i>PS -> PS + V</i> or <i>PS -> gamma + V</i></li>
+<li> 11 : Dalitz decay into one particle, in addition to the
+lepton pair (also allowed to specify a quark-antiquark pair that
+should collapse to a single hadron)</li>
+<li> 12 : Dalitz decay into two or more particles in addition
+to the lepton pair</li>
+<li> 13 : double Dalitz decay into two lepton pairs</li>
+<li> 21 : decay to phase space, but weight up <i>neutrino_tau</i> spectrum
+in <i>tau</i> decay</li>
+<li> 22 : weak decay; if there is a quark spectator system it collapses to
+one hadron; for leptonic/semileptonic decays the <i>V-A</i> matrix element
+is used, for hadronic decays simple phase space</li>
+<li> 23 : as 22, but require at least three particles in decay</li>
+<li> 31 : decays of type B -> gamma X, very primitive simulation where
+X is given in terms of its flavour content, the X multiplicity is picked
+according to a geometrical distribution with average number 2, and
+the photon energy spectrum is weighted up relative to pure phase space</li>
+<li> 42 - 50 : turn partons into a random number of hadrons, picked according
+to a Poissonian with average value as described above, but at least
+<code>code</code> - 40 and at most 10, and then distribute then in pure
+phase space; make a new try with another multiplicity if the sum of daughter
+masses exceed the mother one </li>
+<li> 52 - 60 : as 42 - 50, with multiplicity between <code>code</code> - 50
+and 10, but avoid already explicitly listed non-partonic channels</li>
+<li> 62 - 70 : as 42 - 50, but fixed multiplicity <code>code</code> - 60</li>
+<li> 72 - 80 : as 42 - 50, but fixed multiplicity <code>code</code> - 70,
+and avoid already explicitly listed non-partonic channels</li>
+<li> 91 : decay to <i>q qbar</i> or <i>g g</i>, which should shower
+and hadronize</li>
+<li> 92 : decay onium to <i>g g g</i> or <i>g g gamma</i>
+(with matrix element), which should shower and hadronize</li>
+<li> 100 - : reserved for the description of partial widths of
+<?php $filepath = $_GET["filepath"];
+echo "<a href='ResonanceDecays.php?filepath=".$filepath."' target='page'>";?>resonances</a></li>
+</ul>
+
+Three special decay product identity codes are defined.
+<ul>
+<li>81: remnant flavour. Used for weak decays of c and b hadrons, where the
+c or b quark decays and the other quarks are considered as a spectator
+remnant in this decay. In practice only used for baryons with multiple
+c and b quarks, which presumably would never be used, but have simple
+(copied) just-in-case decay tables. Assumed to be last decay product.</li>
+<li>82: random flavour, picked by the standard fragmentation flavour
+machinery, used to start a sequence of hadrons, for matrix element
+codes in 41 - 80. Assumed to be first decay product, with -82 as second
+and last. Where multiplicity is free to be picked it is selected as for
+normal quarkonic systems. Currently unused.</li>
+<li>83: as for 82, with matched pair 83, -83 of decay products. The
+difference is that here the pair is supposed to come from a closed gluon
+loop (e.g. <i>eta_c -> g g</i>) and so have a somewhat higher average
+multiplicity than the simple string assumed for 82, see the
+<code>ParticleDecays:multGoffset</code> parameter above.</li>
