Rare Semileptonic Meson Decays in R-parity Violating Mssm
In the standard model (SM), lepton L and baryon B number conservation take place due to the accidental U(1)L ×U(1)B symmetry existing at the level of renormalizable operators. But, for many extensions of the SM, this is not the case. The well known mechanism of lepton number (LN) violation is based on the mixing of massive Majorana neutrinos predicted by various Grand unified theories (GUTs) [1...
متن کاملChiral Symmetry and the Parity-Violating NNπ Yukawa Coupling
We construct the complete SU(2) parity-violating (PV) π,N,∆ interaction Lagrangian with one derivative, and calculate the chiral corrections to the PV Yukawa NNπ coupling constant hπ through O(1/Λχ) in the leading order of heavy baryon expansion. We discuss the relationship between the renormalized hπ, the measured value of hπ, and the corresponding quantity calculated microscopically from the ...
متن کامل-Violating Phases in the MSSM
The Minimal Supersymmetric Standard Model (MSSM) contains several new sources for CP violation not present in the Standard Model, and it is well known [1–3] that these phases can produce large SUSY contributions to the electric dipole moments (EDM’s) of the neutron and electron. The common generic description is that these contributions will exceed the current experiment limits on the neutron a...
متن کاملNucleon Charge Symmetry Breaking and Parity Violating Electron-Proton Scattering
The consequences of the charge symmetry breaking effects of the mass difference between the up and down quarks and electromagnetic effects for searches for strangeness form factors in parity violating electron scattering from the proton are investigated. The formalism necessary to identify and compute the relevant observables is developed by separating the Hamiltonian into charge symmetry conse...
متن کاملOn the Neutral Scalar Sector of the General R-parity Violating MSSM
Starting out from the most general, gauge invariant and renormalizable scalar potential of the Rparity violating MSSM and performing a calculable rotation to the scalar fields we arrive at the so called Grossman-Haber basis where the sneutrino VEVs are zero. The advantage of our rotation is that, in addition, we obtain diagonal soft supersymmetry breaking sneutrino masses and all potential para...
