# *
# 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. *
