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...
The conclusions of the Physics Working Group international scoping study a future Neutrino Factory and super-beam facility (the ISS) are presented. ISS was carried by community between NuFact05, 7th International Workshop on Factories Superbeams, Laboratori Nazionali di Frascati, Rome, June 21-26, 2005) NuFact06 (Ivine, California, 24{30 August 2006). physics case for an extensive experimental programme to understand properties neutrino is presented role high-precision measurements...
In the framework of seesaw models with triplets fermions, we evaluate decay rates $\mu \to e \gamma$ and $\tau l transitions. We show that although, due to neutrino mass constraints, those are in general expected be well under present experimental limits, this is not necessarily always case. Interestingly enough, observation one decays planned experiments would nevertheless contradict bounds stemming from limits on eee$ 3 l$ rates. Such detection radiative therefore imply there exist sources...
We discuss the use of massive vectors for interpretation some recent experimental anomalies, with special attention to muon $g-2$. restrict our discussion case where vector is embedded into a spontaneously broken gauge symmetry, so that predictions are not affected by choice an arbitrary energy cut-off. Extended symmetries, however, typically impose strong constraints on mass new boson and $g-2$ they basically rule out, barring abelian extensions, explanation discrepancy in terms single...
We discuss the implementation of “minimal” type III seesaw model, i.e. with one fermionic triplet, in FeynRules/MadGraph. This is first step order to realize a real study LHC data recorded detectors. With this goal mind, we comment on possibility discovering kind new physics at running 7 TeV luminosity few fb−1.
We derive general bounds on the Type-III Seesaw parameters from a global fit to flavor and electroweak precision data. explore compare three realizations: scenario, where an arbitrary number of heavy triplets is integrated out without any further assumption, more constrained cases in which only 3 or 2 (minimal scenario) additional states are included. The latter assumption implies rather non-trivial correlations Yukawa structure model so as reproduce neutrino masses mixings measured...
We classify all possible one-particle (scalar and fermion) extensions of the Standard Model that can contribute to anomalous magnetic moment leptons. review cases already discussed in literature complete picture by performing calculation for a fermionic doublet with hypercharge -3/2. conclude that, out listed possibilities, only two scalar leptoquarks pseudoscalar peculiar two-Higgs-doublet model could be responsibles muon discrepancy. Were this case, particles seen next LHC run. To aim,...
We discuss in detail the possibility that ``type-II Majoron''---that is, pseudo-Nambu-Goldstone boson arises context of type-II seesaw mechanism if lepton number is spontaneously broken by an additional singlet scalar---account for dark matter (DM) observed Universe. study requirements model's parameters have to fulfill order reproduce measured DM relic abundance through two possible production mechanisms early Universe, freeze-in and misalignment, both during a standard radiation-dominated...
We study several aspects of supersymmetric models with a $U(1)_R$ symmetry where the Higgs doublet is identified superpartner lepton. derive new, stronger bounds on gaugino masses based current measurements, and also propose ways to probe model up scales $\mathcal{O}(10\, \textrm{TeV})$ at future $e^+e^-$ colliders. Since cannot be exact, we analyze effects $R$-symmetry breaking neutrino proton decay. In particular, find that getting mixing angles agree experiments in minimal requires UV...
We study the mixing of photons with hypothetical massive spin-two particles in presence a magnetic field. Mixing phenomena have been studied case axionlike and strictly massless (gravitons) but not this case. find several interesting differences between them.
We analyse constraints on the elements of PMNS matrix, mixing matrix in lepton sector, from present experimental data neutrino oscillations as well electroweak decays. Without assuming unitarity oscillation experiments are only sensitive to half elements. The combination with decays allows determine, or bound, all compare our results previous studies, where was assumed, and discuss prospects future for testing sector.
In this thesis we analyze the problem of symmetry breaking in models with extra dimensions compactified on orbifolds. first chapter briefly review main mechanisms peculiar such as Scherk-Schwarz mechanism, Hosotani mechanism and orbifold projection. second study most general boundary conditions for fields S^1/Z_2 apply them to gauge SUSY breaking. third focus flavour present a six dimensional toy model two generations that can solve fermion hierarchy problem.
