SARAH generate calchep/micromegas model files supporting slha1 format

Dear Florian,
How could I set options of MakeCHep[options] in SARAH to generate calchep/micromegas model files that could support slha1 format?

Thank you,
Liang

Typo in inverse-Seesaw-NMSSM

Hi Florian, 1. There is the following stuff in the file SPheno.m in the model inverse-Seesaw-NMSSM in SARAH-4.12.2, BoundaryLowScaleInput={ {vd,Sqrt[4 mz2/(g1^2+g2^2)]*Sin[ArcTan[TanBeta]]}, {vu,Sqrt[4 mz2/(g1^2+g2^2)]*Cos[ArcTan[TanBeta]]} }; but it should be, BoundaryLowScaleInput={ {vd,Sqrt[4 mz2...

Re: Error: Failed to retrieve initial conditions on the first try

Dear Ben,
Thank you for your reply. I want to know if it is reasonable to calculate the tunneling action at T=0 and ignore the non-zero temperature effect. Looking forward to your reply.

Best wishes and regards,
Liang

Re: Error: Failed to retrieve initial conditions on the first try

Dear Ben, Thank you for your reply. I did as your suggestion. And I got the following result successfully. But I am not sure I could use this result because of the warning message, which indicates that our parameter point is long-lived. What’s more, could I ignore this warning message? Best wishes a...

Error: Failed to retrieve initial conditions on the first try

Dear Florian, I have used the Spheno to generate the spectrum for Vevacious in the NMSSM. But I still got some error as the followings: File "./CosmoTransitions-master/cosmoTransitions/pathDeformation.py", line 957, in fullTunneling profile1D = tobj.findProfile(**tunneling_findProfile_params) File "...

Re: Error messages of 'Barrier height is not positive’ and ‘V(phi_metaMin) <= V(phi_absMin)’ in Vevacious-1.2.1

Dear Eliel,
Thank you for your reply.
But I have one more question. What’s the inputting parameters for the potential you choose. Is it M_su^2, M_sq^2, etc. or others? In our work, we scan for tan\beta, so vu and vd are inputting parameters for the potential.

Best wishes and regards,
Liang

Error messages of 'Barrier height is not positive’ and ‘V(phi_metaMin) <= V(phi_absMin)’ in Vevacious-1.2.1

Dear, When we use the model file pure_SLHA2_NMSSM_JustNormalHiggsAndSingletVevs.vin to calculate the stability of the parameter point named spectr12.dat which is in the attachment. We find the error message (labeled as E1): tunneling1D.PotentialError: ('Barrier height is not positive, does not exist...

I got the following errors, tunneling1D.PotentialError: ('Barrier height is not positive, does not exist.', 'no barrier') Minimizing the one-loop potential, calculating the tunneling time or its upper bound, a...
