#********************************************************************* # MadGraph/MadEvent * # http://madgraph.hep.uiuc.edu * # * # param_card.dat * # * # Les Houches friendly file for the SM parameters of MadGraph * # Spectrum and decay widths produced by SMCalc * # * # Please note the following IMPORTANT issues: * # * # 0. REFRAIN from editing this file by hand! Some of the parame- * # ters are not independent * # (such as G_Fermi, alpha_em, sin(theta_W),MZ,MW) and serious * # problems might be encountered (such as violation of unitarity * # or gauge invariance). Always use a calculator. * # * # 1. alpha_S(MZ) has been used in the calculation of the parameters * # but, for consistency, it will be reset by madgraph to the * # value expected IF the pdfs for collisions with hadrons are * # used. This value is KEPT by madgraph when no pdf are used * # lpp(i)=0 . * # * # 2. Values of the charm and bottom kinematic (pole) masses are * # those used in the matrix elements and phase space UNLESS they * # are set to ZERO from the start in the model (particles.dat) * # This happens, for example, when using 5-flavor QCD where * # charm and bottom are treated as partons in the initial state * # and a zero mass might be hardwired in the model definition. * # * ##******************************************************************** Block MODSEL # Select Model 0 1 # 0 1 = SM Block SMINPUTS # Standard Model inputs 1 1.27900000E+02 # alpha_em(MZ)(-1) SM MSbar 2 1.16600000E-05 # G_Fermi 3 1.18000000E-01 # alpha_s(MZ) SM MSbar 4 9.15445065E+01 # Z mass (as input parameter) Block MGYUKAWA # Yukawa masses m/v=y/sqrt(2) # PDG YMASS 5 4.20000000E+00 # mbottom for the Yukawa y_b 4 1.25000000E+00 # mcharm for the Yukawa y_c 6 1.74300000E+02 # mtop for the Yukawa y_t 15 1.77700000E+00 # mtau for the Yukawa y_ta Block MGCKM # CKM elements for MadGraph 1 1 9.75000000E-01 # Vud for Cabibbo matrix Block MASS # Mass spectrum (kinematic masses) # PDG Mass 4 1.40000000E+00 # charm pole mass 5 4.20000000E+00 # bottom pole mass 6 1.74300000E+02 # top pole mass 15 1.77700000E+00 # tau mass 23 9.15445065E+01 # Z mass 24 8.02673592E+01 # W mass 25 1.20000000E+02 # H mass
