This chapter of the report "Flavor in era LHC" Workshop discusses theoretical, phenomenological and experimental issues related to flavor phenomena charged lepton sector conserving CP-violating processes. We review current limits main theoretical models for structure fundamental particles. analyze consequences available data, setting constraints on explicit beyond standard model, presenting benchmarks discovery potential forthcoming measurements both at LHC low energy, exploring options...
Neutrino masses originate most likely at some high energy scale M≫M Z . To obtain reliable predictions for neutrino and mixing angles one has to take into account quantum corrections which, in cases of degenerate or partly spectra, can significantly change the pattern angles. We review calculation these case which are effectively described by single dimension 5 operator. In framework Standard Model its minimal supersymmetric extension we discuss both renormalization group equations (RGE) low...
We present the results of complete one-loop computation ${B}_{d,s}^{0}\ensuremath{\rightarrow}{l}^{+}{l}^{\ensuremath{-}}$ decay rate in MSSM. Both sources FCNC, CKM matrix and off-diagonal entries sfermion mass matrices are considered. Strong enhancement branching ratio (compared to SM prediction) can be obtained large $\mathrm{tan}\ensuremath{\beta}\ensuremath{\sim}{m}_{t}{/m}_{b}$ regime which neutral Higgs boson ``penguin'' diagrams dominate. make explicit strong dependence this on top...
We present an analysis of the discovery reach for supersymmetric particles at upgraded Tevatron collider, assuming that SUSY breaking results in universal soft parameters grand unification scale, and lightest particle is stable neutral. first a review literature, including issues unification, renormalization group evolution supersymmetry effect radiative corrections on effective low energy couplings masses theory. consider experimental bounds coming from direct searches those arising...
We point out a novel possible mechanism by which the electroweak hierarchy problem can be avoided in (effective) quantum field theory. Assuming existence of UV complete underlying fundamental theory and treating cutoff scale $\Lambda$ effective as real physical we argue that would solved if coefficient front quadratic divergences vanished for some choice $\Lambda$, mass parameters fixed at were hierarchically smaller than itself. While this most probably cannot work Standard Model is to...
Present neutrino data are consistent with masses arising from a common seed at some "neutrino unification" scale M(X). Such simple theoretical ansatz naturally leads to quasidegenerate neutrinos that could lie in the electron-volt range mass splittings induced by renormalization effects associated supersymmetric thresholds. In such scheme leptonic analog of Cabibbo angle straight theta(middle dot circle) describing solar oscillations is nearly maximal. Its exact value correlated smallness...
A mechanism of double protection the Higgs potential, by supersymmetry and a global symmetry, is investigated in class supersymmetric models with SU(3)xSU(3)xU(1) gauge symmetry. In such electroweak symmetry can be broken no fine-tuning at all.
