38 Parameters in COMMON BLOCK PYQPAR can be varied by user:
41 COMMON /pyqpar/ T0,tau0,nf,ienglu,ianglu
43 T0 - initial temparature of quark-gluon plasma
44 (allowed range is 0.2 GeV < T0 < 2 GeV, default value is T0=1 GeV);
46 tau0 - proper time of quark-gluon plasma formation
47 (allowed range is 0.01 < tau0 < 10 fm/c, default value is tau0=0.1 fm/c)
49 nf - number of active quark flavours in quark-gluon plasma
50 (nf=0, 1, 2 or 3, default value is nf=0);
52 ienglu - flag to fix type of medium-induced partonic energy loss
53 (ienglu=0 - radiative and collisional loss,
54 ienglu=1 - radiative loss only, ienglu=2 - collisional loss only,
55 default value is ienglu=0);
57 ianglu - flag to fix type of angular distribution of emitted gluons
58 (ianglu=0 - small-angular, ianglu=1 - wide-angular, ianglu=2 - collinear,
59 default value is ianglu-0).
61 NOTE! If specified by user value of such parameter is out of allowed range,
62 the default value is used in PYQUEN run.
64 NOTE! Default parameters of quark-gluon plasma (T0, tau0, nf) were selected as
65 an estimation for LHC heavy ion beam energies.
