Re: right-sneutrino

Thank you for your prompt response. Yes, indeed I am using Mathematica 9. I will run the file with Mathematica 10. Could you also kindly address my second query in the previous post, if possible : " Further, is it possible to implement chargino_1--> neutralino_1 + pion(s) in the SPheno files generat...

right-sneutrino

Hi Florian, I have implemented a model extending the MSSM with three generations of right-neutrino superfields. Because of the presence of a Majorana term (M N^c N^c) in the superpotential, and the corresponding soft-term, there are six CP-even and six CP-odd sneutrino mass eigenstates in the sneutr...

Re: Gauge dependence

Thanks again. Now it prints the block ZZ. I have removes the Theta_Wp parametrization of ZZ as well. However, while h_SM-> ZD ZD shows about the same value (less than 10% off) in both gauges, h_SM-> Z ZD turns out to be very different (by 3 orders of magnitude) in CalcHEP. I am in the process of ana...

Re: Gauge dependence

Thanks Florian. But even when I remove the dependence for ZZ, the block is not written in the SPheno output file. Now I have the following description for ZZ in the parameters.m file : {ZZ, { LaTeX -> "Z^{\\gamma Z Z'}", LesHouches -> ZMx, OutputName -> ZZ}}, But this matrix is not present in the SP...

Re: Gauge dependence

Thanks for the prompt response again. I have two questions : We already have flag 55 set to 0. Although the kinetic mixing may originate generally from loop-induced processes, we are only treating it as a (small) "tree-level" parameter in this case. There is no particle which is charged both under U...

Re: Gauge dependence

Thanks Florian. Since we are interested in the region MZD (mass of the "dark photon") < MZ, I have used the following ordering : {{VB,VWB[3],VBp},{VP,VZp,VZ},ZZ} in the gauge sector. In the pseudoscalar sector I have "{{sigmaH,sigmaB},{Ah,ZA}}," (where sigmaB comes from the "dark Higgs" and finally ...
