We compute the O(α t α s) two–loop corrections to the neutral Higgs boson masses in the Minimal Supersymmetric extension of the Standard Model. An appropriate use of the effective potential allows us to obtain simple analytical formulae, valid for arbitrary values of m A and of the mass parameters in the stop sector. We elucidate some subtleties of the(More)
We study the O(α t α s +α 2 t) two–loop corrections to the minimization conditions of the MSSM effective potential, providing compact analytical formulae for the Higgs tadpoles. We connect these results with the renormalization group running of the MSSM parameters from the grand unification scale down to the weak scale, and discuss the corrections to the(More)
On the two–loop Yukawa corrections to the MSSM Higgs boson masses at large tan β Abstract We complete the effective potential calculation of the two–loop, top/bottom Yukawa corrections to the Higgs boson masses in the Minimal Supersymmetric Standard Model, by computing the O(α 2 t + α t α b + α 2 b) contributions for arbitrary values of the bottom Yukawa(More)
We present the Flavour Les Houches Accord (FLHA) which specifies a set of conventions for flavour-related parameters and observables. The FLHA uses the generic SUSY Les Houches Accord (SLHA) file structure. It defines the relevant Standard Model masses, Wilson coefficients, decay constants, bag parameters, flavour observ-ables, etc. The accord provides a(More)
We address the µ problem of gauge mediation by considering a singlet chiral superfield coupled to the Higgs and messenger fields. We compute the soft terms generated below the messenger scale and study the phenomenological consequences of the model. The experimental bound on the Higgs mass provides a severe constraint that identifies three special regions(More)
