Triple Higgs coupling
Hi!
In the restricitons on matrix elements section, there is a method given to restrict triple higgs coupllings.
^c1:c2:c3[H,H,H] and described as "exclude all triple Higgs couplings with ci constants".
So, I wanted to use this to restrict only triple higgs coupling in the process e1, E1=>H,H,Z. My code looks like this at the moment:
alias q = b
alias Q = B
process proc_3h = e1, E1 => H, H, Z {$restrictions = "1+2 ~ Z && !A && ^0:0:0[H,H,H]"}
$restrictions = "^0:0:0[H,H,H]"
process proc_hbb = H => q, Q
unstable H (proc_hbb)
sqrts = 600 GeV
luminosity = 1e4
$sample = "eventfile"
sample_format = lhef
?vis_channels = true
simulate (proc_3h)
This method did not work. Could you please give an example on how to use this restriction or a more detailed explanation of what c1, c2 and c3 are and whether I need to change the "[H,H,H]" part?
Thanks in advance,
Nikhil
