C Order Alpha_s processes in charged lepton-hadron collisions
C
C Process code IPROC has to be set in the Main Program
C the following codes IPROC may be selected
C
C 9100 : NC BOSON-GLUON FUSION
C 9100+IQK (IQK=1,...,6) : produced flavour is IQK
C 9107 : produced J/psi + gluon
C
C 9110 : NC QCD COMPTON
C 9110+IQK (IQK=1,...,12) : struck parton is IQK
C
C 9130 : NC order alpha_s processes (9100+9110)
C
C Select maximum and minimum generated flavour when IQK=0
C setting IFLMIN and IFLMAX in the Main Program
C (allowed values from 1 to 6), default are 1 and 5
C allowing d,u,s,c,b,dbar,ubar,sbar,cbar,bbar
C
C CHARGED CURRENT Boson-Gluon Fusion processes
C 9141 : CC s cbar (c sbar)
C 9142 : CC b cbar (c bbar)
C 9143 : CC s tbar (t cbar)
C 9144 : CC b tbar (t bbar)
C
C other inputs : Q2MIN,Q2MAX,YBMIN,YBMAX,PTMIN,EMMIN,EMMAX
C when IPROC=(1)9107 : as above but Q2WWMN, Q2WWMX substitute
C Q2MIN and Q2MAX (EPA is used); ZJMAX cut
C
C Add 10000 to suppress soft remnant fragmentation
C
C Mean EVWGT = cross section in nanoBarn

BLOCK DATA HWUDAT
C-----------------------------------------------------------------------
C Loads common blocks with particle properties data; for particle I:
C RNAME(I) = Name
C IDPDG(I) = PDG code
C IFLAV(I) = HERWIG flavour code
C ICHRG(I) = Electric charge (|e-|) (*3 for (di-)quarks)
C RMASS(I) = Mass (GeV/c^2)
C RLTIM(I) = Proper life time (s)
C RSPIN(I) = Spin
C QORQQB(I) = .TRUE. if it is a quark or an antidiquark
C QBORQQ(I) = .TRUE. if it is an antiquark or a diquark
C And stores the particle decay tables: call HWUDPR to print them

C Sets up internal pointers based on the decay table in HWUDAT or as
C supplied via HWIODK. Computes CoM momenta of two-body decay modes.
C Particles with long lifetimes or no allowed decay (excepting light
C b hadrons when CLEO/EURODEC decays requested) are set stable, else
C calculate DKLTM(I) = mass/width ( = mass * lifetime/hbar).
C Gives warnings if: a particle has no decay modes or antiparticle's
C modes are not the charge conjugates of the particles.

C...SaSgam version 2 - parton distributions of the photon
C...by Gerhard A. Schuler and Torbjorn Sjostrand
C...For further information see Z. Phys. C68 (1995) 607
C...and CERN-TH/96-04 and LU TP 96-2.
C...Program last changed on 18 January 1996.
C
C!!!Note that one further call parameter - IP2 - has been added
C!!!to the SASGAM argument list compared with version 1.
C
C...The user should only need to call the SASGAM routine,
C...which in turn calls the auxiliary routines SASVMD, SASANO,
C...SASBEH and SASDIR. The package is self-contained.
C
C...One particular aspect of these parametrizations is that F2 for
C...the photon is not obtained just as the charge-squared-weighted
C...sum of quark distributions, but differ in the treatment of
C...heavy flavours (in F2 the DIS relation W2 = Q2*(1-x)/x restricts
C...the kinematics range of heavy-flavour production, but the same
C...kinematics is not relevant e.g. for jet production) and, for the
C...'MSbar' fits, in the addition of a Cgamma term related to the
C...separation of direct processes. Schematically:
C...PDF = VMD (rho, omega, phi) + anomalous (d, u, s, c, b).
C...F2 = VMD (rho, omega, phi) + anomalous (d, u, s) +
C... Bethe-Heitler (c, b) (+ Cgamma (d, u, s)).
C...The J/psi and Upsilon states have not been included in the VMD sum,
C...but low c and b masses in the other components should compensate
C...for this in a duality sense.
C
C...The calling sequence is the following:
C CALL SASGAM(ISET,X,Q2,P2,IP2,F2GM,XPDFGM)
C...with the following declaration statement:
C DIMENSION XPDFGM(-6:6)
C...and, optionally, further information in:
C COMMON/SASCOM/XPVMD(-6:6),XPANL(-6:6),XPANH(-6:6),XPBEH(-6:6),
C &XPDIR(-6:6)
C COMMON/SASVAL/VXPVMD(-6:6),VXPANL(-6:6),VXPANH(-6:6),VXPDGM(-6:6)
C...Input: ISET = 1 : SaS set 1D ('DIS', Q0 = 0.6 GeV)
C = 2 : SaS set 1M ('MSbar', Q0 = 0.6 GeV)
C = 3 : SaS set 2D ('DIS', Q0 = 2 GeV)
C = 4 : SaS set 2M ('MSbar', Q0 = 2 GeV)
C X : x value.
C Q2 : Q2 value.
C P2 : P2 value; should be = 0. for an on-shell photon.
C IP2 : scheme used to evaluate off-shell anomalous component.
C = 0 : recommended default, see = 7.
C = 1 : dipole dampening by integration; very time-consuming.
C = 2 : P_0^2 = max( Q_0^2, P^2 )
C = 3 : P'_0^2 = Q_0^2 + P^2.
C = 4 : P_{eff} that preserves momentum sum.
C = 5 : P_{int} that preserves momentum and average
C evolution range.
C = 6 : P_{eff}, matched to P_0 in P2 -> Q2 limit.
C = 7 : P_{eff}, matched to P_0 in P2 -> Q2 limit.
C...Output: F2GM : F2 value of the photon (including factors of alpha_em).
C XPFDGM : x times parton distribution functions of the photon,
C with elements 0 = g, 1 = d, 2 = u, 3 = s, 4 = c, 5 = b,
C 6 = t (always empty!), - for antiquarks (result is same).
C...The breakdown by component is stored in the commonblock SASCOM,
C with elements as above.
C XPVMD : rho, omega, phi VMD part only of output.
C XPANL : d, u, s anomalous part only of output.
C XPANH : c, b anomalous part only of output.
C XPBEH : c, b Bethe-Heitler part only of output.
C XPDIR : Cgamma (direct contribution) part only of output.
C...The above arrays do not distinguish valence and sea contributions,
C...although this information is available internally. The additional
C...commonblock SASVAL provides the valence part only of the above
C...distributions. Array names VXPVMD, VXPANL and VXPANH correspond
C...to XPVMD, XPANL and XPANH, while XPBEH and XPDIR are valence only
C...and therefore not given doubly. VXPDGM gives the sum of valence
C...parts, and so matches XPDFGM. The difference, i.e. XPVMD-VXPVMD
C...and so on, gives the sea part only.
