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...
We prove that taking correctly into account the lepton flavour dependence of $CP$ asymmetries and washout processes, it is possible to obtain successful thermal leptogenesis from decays second right-handed neutrino. The in muon tau-flavour channels are then not erased by inverse lightest neutrino ${N}_{1}$. In this way, we reopen possibility ``thermal leptogenesis'' models with a strong hierarchy Majorana masses typically case up-quark neutrino-Yukawa unification.
The MoEDAL experiment at Point 8 of the LHC ring is seventh and newest experiment. It dedicated to search for highly-ionizing particle avatars physics beyond Standard Model, extending significantly discovery horizon LHC.

Another novel feature use...
MoEDAL is designed to identify new physics in the form of long-lived highly ionizing particles produced high-energy LHC collisions. Its arrays plastic nuclear-track detectors and aluminium trapping volumes provide two independent passive detection techniques. We present here results a first search for magnetic monopole production 13 TeV proton-proton collisions using technique, extending previous publication with 8 data during Run 1.

MoEDAL is designed to identify new physics in the form of stable or pseudostable highly ionizing particles produced high-energy Large Hadron Collider (LHC) collisions. Here we update our previous search for magnetic monopoles Run 2 using full trapping detector with almost four times more material and twice integrated luminosity. For first time at LHC, data were interpreted terms photon-fusion monopole direct production addition Drell-Yan-like mechanism. The detector, consisting 794 kg...
The stringent experimental bound on μ → eγ is compatible with a simultaneous and sizable new physics contribution to the electron muon anomalous magnetic moments (g − 2)ℓ (ℓ = e, μ), only if we assume non-trivial flavor structure of dipole operator coefficients. We propose mechanism in which realization correction manifestly related mass generation through symmetry. A radiative flavon fermion gives moment. In this framework, introduce chiral enhancement from $$ \mathcal{O} (1) quartic...
In spite of the large lepton flavour violation (LFV) observed in neutrino oscillations, within Standard Model, we do not expect any visible LFV charged sector (μ → e, γ, τ μ, etc). On contrary, presence new physics close to electroweak scale can enhance amplitudes these processes. We discuss this general and focus on a particularly interesting case: marriage low-energy supersymmetry (SUSY) seesaw mechanism for masses (SUSY seesaw). Several ideas presented context are reviewed both bottom-up...
We update our previous search for trapped magnetic monopoles in LHC Run 2 using nearly six times more integrated luminosity and including additional models the interpretation of data. The MoEDAL forward trapping detector, comprising 222 kg aluminium samples, was exposed to 2.11 fb−1 13 TeV proton–proton collisions near LHCb interaction point analysed by searching induced persistent currents after passage through a superconducting magnetometer. Magnetic charges equal Dirac charge or above are...
We implement the asymmetric dark matter framework, linking ordinary and abundances, within a supersymmetric context. consider model that respects an approximate $U(1)_R$ symmetry, which is broken in such way at high temperature $R$ breaking sector mediate processes equilibrium, but SUSY mass scale, sparticles asymmetry frozen. In this gravitino serves as candidate, its predicted to be $\sim10$ GeV match observed relic abundance. identify several realistic spectra; however, requirement for...
This search for magnetic monopoles (MMs) and high electric charge objects (HECOs) with spins 0, 1/2, 1, uses the first time full MoEDAL detector, exposed to 6.46 fb^{-1} proton-proton collisions at 13 TeV. The results are interpreted in terms of Drell-Yan photon-fusion pair production. Mass limits on direct production MMs up 10 Dirac charges HECOs range 10e 400e, were achieved. placed MM HECO currently strongest world. is only LHC experiment capable being directly calibrated highly ionizing...
The MoEDAL trapping detector, consists of approximately 800 kg aluminium volumes. It was exposed during Run-2 the LHC program to 6.46 fb^-1 13 TeV proton-proton collisions at LHCb interaction point. Evidence for dyons (particles with electric and magnetic charge) captured in detector sought by passing volumes comprising through a SQUID magnetometer. presence trapped dyon would be signalled persistent current induced On basis Drell-Yan production model, we exclude charge ranging up 5 Dirac...
Motivated by the recent Xenon1T result, we study a leptophilic flavour-dependent anomaly-free axion-like particle (ALP) and its effects on charged-lepton flavour violation (CLFV). We present two representative models. The first one considers that ALP origins from flavon generates masses. second model assumes larger symmetry such more general mixings in are possible, while maintaining couplings. find keV explaining result is still viable for lepton stellar cooling astrophysical limits. On...
We study the implications on flavor changing neutral current and $\mathrm{CP}$ violating processes in context of supersymmetric theories without a new structure (flavor blind supersymmetry). The low-energy parameters are determined by running soft breaking terms from grand unified scale with (SUSY) phases consistent electric dipole moment constraints. find that asymmetry $\stackrel{\ensuremath{\rightarrow}}{b}s\ensuremath{\gamma}$ can reach large values potentially measurable at B factories,...
Abstract The confirmation of the discrepancy with Standard Model predictions in anomalous magnetic moment by Muon g-2 experiment at Fermilab points to a low scale new physics. Flavour symmetries broken energies can account for this but these models are much more restricted, as they would also generate off-diagonal entries dipole matrix. Therefore, if we assume that observed muon $$g-2$$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mrow> <mml:mi>g</mml:mi> <mml:mo>-</mml:mo>...

In the context of supersymmetric grand unified theories with soft breaking terms arising at Planck scale, it is generally possible to link flavor changing neutral current and CP violating processes occurring in leptonic hadronic sectors. We study correlation between squark slepton mass insertions models à la SU(5). show that constraints coming from lepton violation exhibit a strong impact on CP-violating B decays.

The hierarchical structure of fermion masses and mixings strongly suggests an underlying family symmetry. In supergravity any familon field spontaneously breaking this symmetry necessarily acquires F-term which contributes to the soft trilinear couplings. We show, as a result, mu -> e gamma decay can receive large contributions from source at level current experimental bounds thus channel may provide first indication supersymmetry clue sector. Using mercury EDM we find strong on right handed...
When the mass difference between lightest slepton, next to supersymmetric particle, and neutralino, is smaller than tau mass, lifetime of slepton increases in many orders magnitude with respect typical lifetimes other particles. These small differences are possible minimal standard model (MSSM) and, for instance, they correspond coannihilation region constrained MSSM ${M}_{1/2}\ensuremath{\gtrsim}700\text{ }\text{ }\mathrm{GeV}$. In a general gravity-mediated MSSM, where particle inversely...
