NON - STANDARD ASSIGNMENTS OF THE r LEPTON WITHIN SIJ
نویسنده
چکیده
ABSTRClCT Within the context of SU(2)BU(l), alternative multiplet assignments for the r lepton and possible accompanying neutralleptons are investigated. Currently available experimental data is sufficient to rule out many alternatives to the standard assignment of the left-handed r to a weak isospin doublet (with,massless vr partner) and the right-handed 'I: to a singlet.

Durable intermediate-to long-term outcomes after minimally invasive transiliac sacroiliac joint fusion using triangular titanium implants
BACKGROUND Sacroiliac joint (SIJ) fusion (SIJF), first performed 95 years ago, has become an increasingly accepted surgical option for chronic SIJ dysfunction. Few studies have reported intermediate- or long-term outcomes after SIJF. OBJECTIVE The objective of this study is to determine patient-based outcomes after SIJF for chronic SIJ dysfunction due to degenerative sacroiliitis or SIJ disru...
متن کاملNew fermion mass textures from anomalous U(1) symmetries with baryon and lepton number conservation
In this paper, we present solutions to the fermion mass hierarchy problem in the context of the minimal supersymmetric standard theory augmented by an anomalous family–dependent U(1)X symmetry. The latter is spontaneously broken by non–zero vevs of a pair of singlet fields whose magnitude is determined through the D– and F–flatness conditions of the superpotential. We derive the general solutio...
متن کاملStability of the Lepton-Flavor Mixing Matrix Against Quantum Corrections
Recent neutrino experiments suggest the strong evidences of tiny neutrino masses and the lepton-flavor mixing. Neutrino-oscillation solutions for the atmospheric neutrino anomaly and the solar neutrino deficit can determine the texture of neutrino mass matrix according to the neutrino mass hierarchies as Type A: m3 ≫ m2 ∼ m1, Type B: m3 ≪ m2 ∼ m1, and Type C: m3 ∼ m2 ∼ m1. In this paper we stud...
متن کاملDiscrete gauge symmetries and proton stability in the U(1)-extended MSSM
The Minimal Supersymmetric Standard Model (MSSM) with conserved Rparity suffers from several fine-tuning problems, e.g. the μ-problem and the problem of proton decay through higher dimension operators. Both of these problems can be avoided by replacing R-parity with a non-anomalous U(1)′ gauge symmetry which is broken at the TeV scale. The new gauge symmetry does not necessarily forbid all reno...
متن کاملMeasuring Lepton Flavour Violation at LHC with Long-Lived Slepton in the Coannihilation Region
High precision electroweak tests, such as deviations from the Standard Model expectations of the Lepton Flavor Universality (LFU) breaking in K → lνl (with l = e or μ), represent a powerful tool to test the Standard Model and, hence, to constrain or obtain indirect hints of New Physics beyond it. We explore such a possibility within Supersymmetric theories. Interestingly enough, a process that ...
