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...
In this work the following lepton flavor violating $\ensuremath{\tau}$ and $\ensuremath{\mu}$ decays are studied: ${\ensuremath{\tau}}^{\ensuremath{-}}\ensuremath{\rightarrow}{\ensuremath{\mu}}^{\ensuremath{-}}{\ensuremath{\mu}}^{\ensuremath{-}}{\ensuremath{\mu}}^{+}$, ${\ensuremath{\tau}}^{\ensuremath{-}}\ensuremath{\rightarrow}{e}^{\ensuremath{-}}{e}^{\ensuremath{-}}{e}^{+}$, ${\ensuremath{\mu}}^{\ensuremath{-}}\ensuremath{\rightarrow}{e}^{\ensuremath{-}}{e}^{\ensuremath{-}}{e}^{+}$,...
In this paper we consider a Higgs boson with mass and other properties compatible those of the recently discovered particle at LHC, explore possibility new leptonic decays, beyond standard model, singular feature being lepton flavor violating (LFV). We study these LFV $H\ensuremath{\rightarrow}{l}_{k}{\overline{l}}_{m}$, within context inverse seesaw model (ISS) most generic case where three additional pairs massive right-handed singlet neutrinos are added to content. require in addition...
Lepton flavor violating Higgs boson decays are studied within the context of seesaw models with Majorana massive neutrinos. Two considered: The SM-seesaw, Standard Model Particle content plus three right handed neutrinos, and MSSM-seesaw, Minimal Supersymmetric particle neutrinos their supersymmetric partners. widths for these derived from a full one-loop diagrammatic computation in both models, they analyzed numerically terms parameters, namely, Dirac mass matrices. Several possible...
In this article, we study the full one-loop SUSY contributions to lepton flavor violating Higgs decay $h\ensuremath{\rightarrow}\ensuremath{\tau}\overline{\ensuremath{\mu}}$, within context of supersymmetric inverse seesaw model. We assume that both right-handed neutrino masses, ${M}_{R}$, and their partner ${m}_{{\stackrel{\texttildelow{}}{\ensuremath{\nu}}}_{R}}$, are not far from interesting $\mathcal{O}(\mathrm{TeV})$ energy scale, work with scenarios large Yukawa couplings transmit...
In this letter we study new relevant phenomenological consequences of the right-handed heavy neutrinos with masses at ${\cal O}(1)$ TeV energy scale, working within context Inverse Seesaw Model that includes three pairs quasi-degenerate pseudo-Dirac neutrinos. We propose a exotic signal these CERN Large Hadron Collider containing muon, tau lepton, and two jets in final state, which is based on interesting fact model can incorporate large Lepton Flavor Violation for specific choices...
In this work, we explore the low-energy effects induced from integration of heavy Higgs boson modes $H$, $A$, and ${H}^{\ifmmode\pm\else\textpm\fi{}}$ within two-Higgs-doublet model (2HDM) by assuming that lightest $h$ is one observed experimentally at ${m}_{h}\ensuremath{\sim}125\text{ }\text{ }\mathrm{GeV}$. We work context effective field theories, focusing on theory (HEFT), although some comparisons with Standard Model case are also discussed through work. Our main focus placed in...
Multi-Higgs boson interactions with massive gauge bosons are known to be tell-tale probes of the vacuum manifold electroweak symmetry breaking. Phenomenologically, a precise determination these parameters is hampered through increasingly rare processes at presently available energy frontier provided by Large Hadron Collider.

In this paper we study the Lepton Flavor Violating $Z$ boson decays $Z \to \tau \mu$ and e$ in context of low scale seesaw models with new heavy Majorana neutrinos whose masses could be reachable at LHC. Our computations decay rates are done particular realization given by Inverse Seesaw Model six extra which quasi-degenerate three pseudo-Dirac pairs. particular, focus on scenarios that built ad-hoc to produce suppressed all processes involving $\mu$-$e$ transitions, fact these far most...
In this work we present a new computation of the lepton flavor violating Higgs boson decays that are generated radiatively to one-loop from heavy right-handed neutrinos. We within context inverse seesaw model with three $\nu_R$ and extra singlets $X$, but results could be generalized other low scale models. The novelty our is it uses completely different method by means mass insertion approximation which works electroweak interaction states instead usual 9 physical neutrino eigenstates...
An important task at future colliders is the measurement of triple Higgs coupling. Depending on its size relative to Standard Model (SM) value, certain collider options result in a higher experimental accuracy. Within framework Two Doublet Models (2HDM) type I and II we investigate allowed ranges for all couplings involving least one light, SM-like boson. We take into account theoretical constraints (unitarity, stability), from direct Higgs-boson searches, measurements properties, flavor...
We explore the phenomenological implications on charged lepton flavor violating (LFV) processes from slepton mixing within Minimal Supersymmetric Standard Model (MSSM). work under model-independent hypothesis of general in sector, being parametrized by a complete set dimensionless ${\ensuremath{\delta}}_{ij}^{AB}$ ($A$, $B=L$, $R$; $i$, $j=1$, 2, 3, $i\ensuremath{\ne}j$) parameters. The present upper bounds most relevant LFV processes, together with requirement compatibility choice MSSM...
We explore the phenomenological implications on nonminimal flavor violating (NMFV) processes from squark mixing within minimal supersymmetric standard model (MSSM). work under model-independent hypothesis of general in sector, being parametrized by a complete set dimensionless ${\ensuremath{\delta}}_{ij}^{AB}$ ($A,B=L,R$; $i,j=u,c,t$ or $d,s,b$; $i\ensuremath{\ne}j$) parameters. The present upper bounds most relevant NMFV processes, together with requirement compatibility choice MSSM...
In this work we study the $\gamma\gamma\to W^+_L W^-_L$ and Z_L Z_L$ scattering processes within effective chiral Lagrangian approach, including a light Higgs-like scalar as dynamical field together with would-be-Goldstone bosons $w^\pm$ $z$ associated to electroweak symmetry breaking. This approach is inspired by possibility that boson be composite particle behaving another Goldstone boson, assumes existence of mass gap between $m_h$, $m_W$, $m_Z$ potential new emergent resonances, setting...
