Radiative Mechanism to Light Fermion Masses in the MSSM
نویسنده
چکیده
In a previous work we applied a discrete symmetry (Z ′ 2) in order to light fermions acquire mass only at one loop level. This symmetry and the assumption of alignment between fermions and sfermions allow us to avoid FCNC problems. Here a more general hypothesis of flavor mixing in the sfermion sector of MSSM is considered and we show that the s quark is heavier than u, d quarks due to different content of sfermions contributions. Our results are in agreement with the experimental constraint on the values of sfermions masses.

The search for Higgs particles at LEP
The results of the experimental searches for Higgs particles at LEP, using the data collected at centre-of-mass energies up to 189 GeV, are reviewed and the prospects for the near future outlined. The Standard Model (SM) of the electroweak interactions has been subject to very precise tests at LEP and elsewhere. Up to now its prediction have been found in very good agreement with the experiment...
متن کاملFermion Masses at intermediate tan β: Unification of Yukawa Determinants
In the context of the Grand Unified MSSM, we investigate the fermion mass matrices at GUT scale. We note that from the experimental mass pattern the determinants of the Yukawa matrices at this scale can be unified with good precision. Taking the unification o determinants as an hypothesis, it gives two model independent predictions that in the MSSM turns out to determine an appropriate value fo...
متن کاملConstraining the MSSM sfermion mass matrices with light fermion masses
We study the finite supersymmetric loop corrections to fermion masses and mixing matrices in the generic MSSM. In this context the effects of non-decoupling chirally-enhanced self-energies are studied beyond leading order in perturbation theory. These NLO corrections are not only necessary for the renormalization of the CKM matrix to be unitary, they are also numerically important for the light...

The recent failure of the scenario which uses only 10, 126 Higgs multiplets to yield large enough neutrino masses in the SO(10) MSGUT motivates an alternative scenario[1] where the 120 -plet collaborates with the 10 -plet to fit the dominant charged fermion masses. The small 126 -plet couplings give appreciable contributions only to light charged fermion masses and enhance the Type I seesaw mas...
متن کاملRadiative corrections to Higgs boson masses in the next-to-minimal supersymmetric standard model.
We perform a systematic study of radiative corrections to the masses of the Higgs bosons in the minimal supersymmetric standard model (MSSM) augmented by a single gauge singlet, the so-called next-to-minimal supersymmetric standard model (NMSSM). Our method is based on the one-loop effective potential and includes effects of top quark, squark, Higgs and Higgsino loops. We discuss the renormalis...
