We present an effective Lagrangian formalism for the calculation of flavour changing neutral and charged scalar currents in weak decays including SU(2)Ã—U(1) symmetry breaking effects and the effectsâ€¦ (More)

RGEs for coefficients of dim-5 operators giving rise to neutrino masses in the seesaw mechanism are written down in the SM, 2HDM and MSSM, and solved numerically. RG evolution of these coefficientsâ€¦ (More)

We amplify previous discussions of the fine-tuning price to be paid by supersymmetric models in the light of LEP data, especially the lower bound on the Higgs boson mass, studying in particular itsâ€¦ (More)

Present neutrino data are consistent with neutrino masses arising from a common seed at some "neutrino unification" scale M(X). Such a simple theoretical ansatz naturally leads to quasidegenerateâ€¦ (More)

Systematic on-shell renormalization programme is carried out for the Higgs and gauge boson sectors of the Minimal Supersymmetric Standard Model. Complete 1-loop results for the 2and 3-point Greenâ€™sâ€¦ (More)

We compute the low energy threshold corrections to neutrino masses and mixing in the Standard Model (SM) and its minimal supersymmetric version, using the effective theory technique. We demonstrateâ€¦ (More)

We present SUSY FLAVOR â€” a Fortran 77 program that calculates important leptonic and semi-leptonic low-energy observables in the general R-parity conserving MSSM. For a set of input MSSM parameters,â€¦ (More)
