Flavor Violation Theory and Experiment
Rare decays and angular distributions of B mesons are particularly sensitive probes of physics beyond the Standard Model. This talk reviews results on these processes obtained with the data collected by the CMS experiment during the first Run of the LHC. We will show the most precise single-experiment results on the measurement of the Bs->µµ branching fraction and search for Bd->µµ, along with...

The large amount of Heavy Flavour data collected by the ATLAS
experiment is potentially sensitive to New Physics, which may be found
in the mixing of B meson states, or through processes that are
naturally suppressed in the Standard Model. We present the most recent
results on the measurement of the decay of the Bs into J/psi phi based
on full data collected in LHC Run-1 and with updated...

We critically reassess the theoretical uncertainties in the Standard Model calculation of $B \rightarrow K^{*}\mu\,\mu$ observables, focusing on the low $q^{2}$ region. We point out that even optimized observables are affected by sizable uncertainties coming both from full form factors, when one considers the departure from the infinite mass limit, and from long distance effects. In...

Electroweak and radiative penguin b-hadron and c-hadron decays set strong constraints on the SUSY parameter space. Recent LHCb measurements have shown indications of large unexpected asymmetries in
B->K*mumu and hints of lepton universality violation. Latest results involving new decay modes are presented.

B and D mesons provide an ideal laboratory for measurements of CP violation and searches for CPV beyond the Standard Model. We present recent LHCb results on measurements from several decay modes and based on different techniques, including time-dependent, time-integrated and dalitz analyses.

The recent measurement of the branching fractions of the rare B meson decays, $B_d^0 \to \mu^+\mu^-$ and $B_s^0 \to \mu^+\mu^-$, is one of the most impressive achievements of the LHC experiments. The ratio of the branching fractions is about 2 sigma above the standard model prediction. Although the deviation is not very significant in the current statistical status, it is interesting to study...

We present a selection of recent studies performed by using the full data sample collected by the BABAR detector. Among them are a measurement of CP asymmetries in the B0-B0bar mixing process by using inclusive dilepton samples, an angular analysis of the B -> K* l+l- decay, which might indirectly probe the presence of beyond-Standard-Model particles in the loop diagrams, and studies of...

The rare decays $K^+ \rightarrow \pi^+ \nu \nu$ are excellent processes to make tests of new physics at the highest scale complementary to LHC thanks to their theoretically cleaness.
The NA62 experiment at CERN SPS aims to collect of the order of 100 events in two years of data taking, keeping the background at the level of 10%.
Part of the experimental apparatus has been commissioned during...

The question of the validity of analyzing charmed meson decays to pairs of hadrons within the SU(3) framework has been long and often debated. While there are convincing arguments that small breaking of this symmetry can accommodate for the current experimental results, the inability to compute QCD effects in these modes render it quite impossible to justify with complete authority the...

In this talk we present analyses involving Higgs bosons and heavy flavors at high transverse momentum by the CMS Experiment. In particular, we show results on searches for top quark flavor-changing neutral-current (FCNC) and top quark flavor-changing Higgs-current (FCHC) decays. In addition, measurements of the Higgs boson decays to leptons and bottom quarks, together with Lepton Flavor...

The top quark pairs at Tevatron are produced mainly through proton anti-proton
interaction. The asymmetry of this production is intriguing. The search for
new physics beyond the Standard Model is on going using CDF RUN II data. The
latest results of top quark production asymmetry, searching for Fermiophobic
Higgs and FCNC will be given at the conference.

The simplest Grand Unified Theory (GUT) embedding the Standard Model (SM) is based on the SU(5) symmetry. The unification of gauge couplings, failing in the SM, takes place in the R-parity conserving Minimal Supersymmetric Standard Model (MSSM).
We investigated the possibility of satisfying the minimal SU(5) boundary conditions also for Yukawa matrices at the GUT scale within the MSSM. We...

We analyse the Yukawa matrices structure, $\widetilde{ \bf Y}_{ _{1,2} }^{q}$, by assuming a four-zero texture ansatz for their definition, in the frame of the general 2-Higgs Doublet Model. Explicit and exact expressions for $\widetilde{ \bf Y}_{ _{1,2} }^{q}$ are shown. Naturally, these expressions have a functional structure like to Cheng and Sher ansatz. Furthermore, we perform a...

We analyze the effects of (squark and slepton) flavor violation induced by RGE running
from the GUT scale within the CMSSM. We show that these effects, in particular in the
scalar quark sector, can induce corrections to electroweak precision observables that can set
an upper limit on the scalar mass parameter m_0.

Already at tree-level the theoretical prediction for the cross section of
$P P \to {\tilde q_i} {\tilde q_i}^*, \tilde q = \tilde u, \tilde d; i = 1, \ldots, 6$, can have
a strong dependence on squark flavour mixing parameters. Such a case is not taken
into account in any published LHC study up to now. As a logical next step we
calculate the leading one-loop corrections to that...

Various decays of B mesons have sensitive to the physics beyond the Standard Models.
New particles such as SUSY particles might enter in the loop diagram.
Charged scalar particles such as charged Higgs bosons might contribute in addition to the W boson.

Hints of new physics observed in B-physics have lead to considerable interests on the flavor sector and lepton flavor violating (LFV) effects observable at the LHC. Searches for LFV decays of the Standard Model particles or new heavy particles have been conducted at the ATLAS experiment. Run 1 LFV search results are presented in this talk, together with searches for other signatures at ATLAS....

Many models extending the SM to account for dark matter or explain inflation predict the existence of O(1) GeV mass particles with long lifetimes. LHCb's detection capabilities for detached vertices are exploited to search for particles decaying to muon pairs. New results are presented.

We proposed a new charged lepton flavor violation (CLFV) process, $\mu^- e^- \rightarrow e^- e^-$ in a muonic atom, as one of the promising processes to search for new physics beyond the standard model [1]. It was found that the attractive interaction of leptons with the nucleus in the muonic atom enhances the transition rate of the $\mu^- e^- \rightarrow e^- e^-$ process. We report on our...

We consider the case that μ-e conversion signal is discovered but other charged lepton flavor violating (cLFV) processes will never be found. In such a case, we need other approaches to confirm the μ-e conversion and its underlying physics without conventional cLFV searches.
We study R-parity violating (RPV) SUSY models as a benchmark. We briefly review that
our interesting case is realized...

Within low scale seesaw mechanism, in contrast to standard type-I seesaw,
one can get compatible with data light neutrinos with the addition of low scale heavy Majorana neutrinos that can still have large Yukawa couplings, leading to new potentially interesting phenomenology. Taking the Inverse Seesaw model as an explicit realization of this kind of models, we study different aspects of this...

The recent measurement of high energy extragalactic neutrinos by the IceCube
Collaboration has opened a new window to probe non-standard neutrino properties. Among
other effects, sterile neutrino altered dispersion relations (ADRs) due to shortcuts in an extra
dimension can significantly affect astrophysical flavor ratios. We discuss an MSW-like resonant conversion arising from geodesics...

A different finite subgroup of SU(2) for each lepton and each quark family leads to the first-principles determination of the mixing angles for neutrinos, quarks, and their PMNS and CKM mixing matrices. For example, the neutrino $\theta_{13}$ = 8.56$^{\circ}$ and normal hierarchy are predicted. Connections of these subgroups to the j-invariant of elliptic modular functions (and the Monster...
