| 11 | # *
|
|---|
| 12 | # 0. REFRAIN from editing this file by hand! Some of the parame- *
|
|---|
| 13 | # ters are not independent *
|
|---|
| 14 | # (such as G_Fermi, alpha_em, sin(theta_W),MZ,MW) and serious *
|
|---|
| 15 | # problems might be encountered (such as violation of unitarity *
|
|---|
| 16 | # or gauge invariance). Always use a calculator. *
|
|---|
| 17 | # *
|
|---|
| 18 | # 1. alpha_S(MZ) has been used in the calculation of the parameters *
|
|---|
| 19 | # but, for consistency, it will be reset by madgraph to the *
|
|---|
| 20 | # value expected IF the pdfs for collisions with hadrons are *
|
|---|
| 21 | # used. This value is KEPT by madgraph when no pdf are used *
|
|---|
| 22 | # lpp(i)=0 . *
|
|---|
| 23 | # *
|
|---|
| 24 | # 2. Values of the charm and bottom kinematic (pole) masses are *
|
|---|
| 25 | # those used in the matrix elements and phase space UNLESS they *
|
|---|
| 26 | # are set to ZERO from the start in the model (particles.dat) *
|
|---|
| 27 | # This happens, for example, when using 5-flavor QCD where *
|
|---|
| 28 | # charm and bottom are treated as partons in the initial state *
|
|---|
| 29 | # and a zero mass might be hardwired in the model definition. *
