#!/bin/tcsh cd . bbh< hadrons you must make an initial run with f_read_bbh=F c in order to produce the parton distribution files bbhxxx_pzrn, bbhxxx_pzrdat, c and bbhxxx_pzrdat2. Then set f_read_bbh=T and use the generated files as input. The c files bbhxxx_pzrn, bbhxxx_pzrdat, and bbhxxx_pzrdat2 only depend on pt_min_bbh and c ecm_bbh. Thus, you only need to produce a new set of files if you change c pt_min_bbh and/or ecm_bbh. c c For lepton pair production (i_lepton_bbh=11,13,15) use f_read_bbh=.false. . c Lepton pair-production does not include mass effects, so you should run with c pt_min_bbh and cm_isa_bbh well above pair-production threshold. c cf_read_bbh=.true. ! read quark/gluon distrib. f_read_bbh=.false. ! generate quark/gluon distrib. c cpt_min_bbh=1.6d0 ! minimum mini-jet or lepton pair pt in GeV cpt_min_bbh=3.2d0 ! minimum mini-jet or lepton pair pt in GeV pt_min_bbh=0.2d0 ! minimum mini-jet or lepton pair pt in GeV c c c c c NOTE: For now there is no means to turn off minimum bias events. c Thus, if you set f_dir_bbh=.true, f_1res_bbh=.false., c and f_2res_bbh=.false., you will still get mostly c minimum bias events. c c f_dir_bbh=.true. ! include direct processes cf_dir_bbh=.false. ! don't include direct processes c f_1res_bbh=.true. ! include 1-resolved processes cf_1res_bbh=.false. ! don't include 1-resolved processes c f_2res_bbh=.true. ! include 2-resolved processes cf_2res_bbh=.false. ! don't include 2-resolved processes c c c c f_frag_bbh=.true. ! fragment quarks and gluons cf_frag_bbh=.false. ! don't fragment quarks and gluons c cf_dltf_bbh=.true. ! gam-gam ecm spec is delta func at max ecm f_dltf_bbh=.false. ! gam-gam ecm spec is NOT delta func at max ecm c cf_star_bbh=.true. ! use h2res for xsec when 1 jet pair pt>pt_min f_star_bbh=.false. ! don't use h2res for xsec c fbeam_bbh=.true. ! include beamsstr. photons in photon lumi cfbeam_bbh=.false. ! don't include beamsstr. photons in ph lumi c fbrem_bbh=.true. ! include bremsstr. photons in photon lumi cfbrem_bbh=.false. ! don't include bremsstr. photons in ph lumi c f_full_bbh=.true. ! use full expression for w-w spectrum cf_full_bbh=.false. ! only the leading term is kept c f_pskn_bbh=.true. ! q2 is taken from eqn. 3.12 of slac-pub-5873 cf_pskn_bbh=.false. ! q2=q2_cut c c ccm_isa_bbh=2.0d0 ! min gam-gam ecm in GeV for event gen. ccm_isa_bbh=5.0d0 ! min gam-gam ecm in GeV for event gen. cm_isa_bbh=0.4d0 ! min gam-gam ecm in GeV for event gen. xk_bea_bbh=0.001d0 ! minimum beamstr photon energy in GeV cm_dlt_bbh=1000.d0 ! gam-gam ecm in GeV for f_dltf_bbh=.true. c i_cuts_bbh=0 ! =0 no y cuts, =1 implement y cuts yy_cut_bbh=1.5d0 ! y cut for dir & 1-res if i_cut=1 c (no y cut for 2-res processes) c c c c c JLC/NLC0500 8/8/98 c ecm_bbh=515.d0 c xn_bbh=0.95d10 c sx_bbh=330.d-9 c sy_bbh=4.9d-9 c sz_bbh=120.d-6 c betx_bbh=12.d-3 c bety_bbh=0.12d-3 c c JLC/NLC1000 8/8/98 ecm_bbh=1008.d0 xn_bbh=0.95d10 sx_bbh=235.d-9 sy_bbh=3.9d-9 sz_bbh=120.d-6 betx_bbh=12.d-3 bety_bbh=0.15d-3 c c c c c NLC1500 (Modified RRuth Snowmass 96) c ecm_bbh=1500.d0 c xn_bbh=1.10d10 c sx_bbh=202.d-9 c sy_bbh=5.10d-9 c sz_bbh=150.d-6 c betx_bbh=12.d-3 c bety_bbh=0.20d-3 c NEVENT_STD=100 Call go Call HEP2NT(' SUM') Call bbh_exit Stop End quit echo "end of runbbh"
