NMSPEC: A Fortran code for the sparticle and Higgs masses in the NMSSM with GUT scale boundary conditions
Ulrich Ellwanger, Cyril Hugonie
NMSPEC is a Fortran code that computes the sparticle and Higgs masses, as well as Higgs decay widths and couplings in the NMSSM, with soft SUSY breaking terms specified at MGUT. Ex…
A FORTRAN code for in SM and MSSM
Th. Diakonidis, G. J. Gounaris, J. Layssac
Through the present paper, the code gamgamZZ is presented, which may be used to calculate all possible observables related to the process , in either the Standard Model (…
The upper bound on the lightest Higgs mass in the NMSSM revisited
Ulrich Ellwanger, Cyril Hugonie
We update the upper bound on the lightest CP even Higgs mass in the NMSSM, which is given as a function of tan(beta) and lambda. We include the available one and two loop correctio…
Supersymmetry spectroscopy in stop-chargino production at LHC
M. Beccaria, G. Macorini, L. Panizzi +2
We consider the process of associated stop-chargino production in the MSSM at LHC and show that, at the simplest Born level, the production rate is dramatically sensitive to the ch…
Single top production in the -channel at LHC: a realistic test of electroweak models
M. Beccaria, G. Macorini, F. M. Renard +1
We compute the complete electroweak one-loop effect on the process of -channel single top production at LHC in the Standard Model and in the MSSM within the mSUGRA symmetry brea…
Addendum to "Helicity conservation in gauge boson scattering at high energy"
G. J. Gounaris, F. M. Renard
In a previous paper we have established that for any two-body process involving even numbers of transverse vector bosons and gauginos, the dominant asymptotic amplitudes obey helic…
