Lepton flavor violation (LFV) research is currently one of the most exciting branches of particle physics due to its high sensitivity
to new physics. The observation of neutrino oscillations has clearly demonstrated that neutral lepton flavor is not conserved. This
implies that charged LFV (cLFV) processes, such as the mu+ -> e+ gamma
decay, can also occur in the Standard Model (SM),...

The Mu2e experiment will measure the charged-lepton flavor violating (CLFV) neutrino-less conversion of a negative muon into an electron in the field of a nucleus. The conversion process results in a monochromatic electron with an energy slightly below the muon rest mass. Mu2e will improve the previous measurement by four orders of magnitude using a new technique, reaching a SES (single event...

From the experimental observation of neutrino oscillations, lepton flavor violation (LFV) in the neutrino sector has been observed. However, that violation has not yet been observed in the charged-lepton sector and it is not quite certain where it is most likely to be observed first. The most promising LFV low-energy channels are probably mu and tau decays in to one lepton and gamma.
We...

LHC searches with $\tau$ leptons in the final state are always inclusive in missing-energy sources. A signal in the flavor-violating Higgs decay search,$h\to\tau\mu$, could therefore equally well be due to a flavor conserving decay, but with an extended decay topology with additional invisible particles.
In this talk, I demonstrate this with the three-body decay $h\to\tau\mu\varphi$, where...

The charged lepton flavor violation (CLFV) is considered as a promising process to search for new physics beyond the standard model.
Though various CLFV processes have been investigated, so far any clear signals of new physics have not yet found.
The CLFV decay of the muonic atom, $\mu^-e^- \rightarrow e^-e^-$, was proposed as a
promising process by Koike et al. [1].
In this talk, We will...

This talk reports about the search for lepton flavour violation (LFV) and lepton number violation in the data collected by the ATLAS detector during LHC Run1 (8 TeV) and Run2 (13 TeV). Results on the search for Higgs, Z and a hypothetical heavy neutral boson, Z', decays into leptons of different flavor are presented, as well as results on the search for double charged Higgs and tau->3 mu decays.

The standard model of particle physics explicitly conserves lepton flavour in particle interactions in spite of the absence of an underlying symmetry. The observation of neutrino oscillation proves neutral lepton flavour violation (LFV) and thus motivates a search for violations in charged lepton interactions. Models like R-parity violating SUSY or quantum black holes could result in final...

pp collisions at center-of-mass energy of 7 TeV and 8 TeV at the LHC, including latest results on
D0 ->e+mu-, tau+ -> mu+mu-mu+ , and B -> e+mu- decays, and updated discussion of GeV-scale
Majorana neutrinos from B and D decays. A new search is presented for Higgs-like boson decays...

There are measurements in B decays that point to lepton universality violation. These puzzles are in the charged current B-> D^(*) tau \bar{nu}_tau and in the neutral current b-> s ll decays and are known as the R_D* and R_K puzzles. I will discuss how the two puzzles may be related and explore the consequences of this connection. Possible connection between the R_K puzzle and the muon g-2...

We report on a search for single-photon events in 53 fb−1 of e+e− collision data collected with the BABAR detector at the PEP-II B-factory. We look for events with a single high-energy photon and a large missing momentum and energy, consistent with production of a spin-1 particle A’ through the process e+e- -> gamma A’, A’ -> invisible. Such particles, referred to as “dark photons”, are...

Measurements of the ultra-rare K --> pi nu nu decays represent a stringent test of the CKM paradigm, probing short distance scales beyond the reach of the LHC. The main goal of the NA62 experiment at CERN is the measurement of the K+ --> pi+ nu nu decay rate at 10% precision; the broader physics programme includes searches for lepton flavour and lepton number violation in kaon decays at record...

In this talk, we present a brief review of charged lepton flavor violation and lepton number violation results from Belle and discuss prospects with Belle II.
In the standard model (SM), lepton flavors are conserved by accidental symmetries. While the neutrino flavor mixing provides a way for lepton flavor violation (LFV), the observed values of neutrino mixing predicts only very tiny amount...

The charged Lepton Flavor Violation (cLFV) is highly suppressed in the Standard Model (SM) by the finite but tiny neutrino masses. Its branching fraction is calculated to be at a negligible level and so far none has been found in all the historical experiments, including searches in lepton ($\mu$,$\tau$) decays, pseudoscalar meson (K,$\pi$) decays, vector meson ($\phi$,$J/\psi$,$\Upsilon$)...

In 2010 the proton charge radius was extracted for the first time from muonic hydrogen, a bound state of a muon and a proton. The value obtained was five standard deviations away from the regular hydrogen extraction. Taken at face value, this might be an indication of a new force in nature coupling to muons, but not to electrons. It also forces to reexamine our understanding of the structure...

A new scalar boson which couples to the muon and proton can simultaneously solve the proton radius puzzle and the muon anomalous magnetic moment discrepancy. Using a variety of measurements, we constrain the mass of this scalar and its couplings to the electron, muon, neutron, and proton. Making no assumptions about the underlying model, these constraints and the requirement that it solve both...

The quest for the UV completion of the Standard Model can be addressed
not only by means of direct collider signatures of new physics, but also
via the effects of currently inaccessible physics on low-energy
observables. Lepton flavor violating transitions and measurements of the
leptonic magnetic moments offer gripping tests for new physics from low
to high energies. In this talk...
