cross section zero for ZW+ > W+ > cs~

Hi,

I'm confuse, which syntax did you use?
Could you put the content of the proc_card?

Cheers,

Olivier

Olivier hello, and thanks.

I reinstalled MG and then got a result.

Howerver, for MG the result is different from the SM result in CalcHep.

For example, for the run_card.dat below I get 173.1 pb, while for CalcHep (Sqrt[s]=400, no cuts, W width=0) I get 192.5 pb.

I can't figure out why there is a difference.

Below are the run_card and param_card (all widths=0).

Again, thanks very much,

Aviad

Hi,

Did you check the correspondance for
1) mass of the light quark?
2) the ckm value
3) the electroweak scheme. (i.e the mass of the W/Z/alpha_EW/…)

Cheers,

Olivier

Hello, and thanks for your help.

I 'm sorry for not being accurate, as my problem is, in fact, that the process (W2 is a heavy, charged gauge boson in my model)

W+ Z > W2+ > c s~

gives different results in MG (0.00004 pb) and CalcHep (0.00007 pb) (no PDFs used), but the two separate decays

W2+ > W+ Z
W2+ > c s~

give identical results in MG and CH. In addition, the process

c s~ > W2+ > c s~

also gives identical result in MG and CH (0.01129 pb in sqrt[s]=400 GeV),

in contrast to the process

W+ Z > W2+ > W+ Z

which gives two differnt results.

My question is how can this be?

My param_card.dat and run_card.dat are

Hi,

I would bet that this is linked to the fact that your initial state is massive.
I would compare the momenta of the initial particle for each generator to check
if both code use the same convention for the initial momentum in that case.

Cheers,

Olivier hello,

Indeed, I noticed that as I increase the energy, the gap between the programs decreases.

I consider your advise a solution to my problem, and I would like to thank you for your quick response and good will.

Sincerely,
Aviad
