# Madspin decay

Dear Olivier,

I have a similar problem as the one mentioned in this link: https:/

I am trying to compute the cross-section of gg > h2 > h3 Z* > h1 Z* Z*with h1 > b b~, Z*> jj and Z* > mu+ mu- in 2HDM type-I. For that, I used the hgg_plugin, however, there is a difference between the expected one, using the branching ratios from 2HDMC, and the one computed by madgraph and madspin. I checked 3 benchmark points, while including the total width of h, H A and H+ in the parameter Card:

BP1: \sigma (madspin + madgraph ) = 2.5 x \sigma(expected using Brs form 2HDMC)

BP2: \sigma (madspin + madgraph ) = 4 x \sigma(expected using Brs form 2HDMC)

BP3: \sigma (madspin + madgraph ) = 3.5 x \sigma(expected using Brs form 2HDMC)

I tried to set the total width to Auto. But I am getting an error message :

ERROR: Invalid command: 25 is not a valid argument for compute_widths

Command "launch" interrupted with error:

ValueError : invalid literal for int() with base 10: 'autoautoautoau

Many thanks for any help or any suggestion

Best regards
