Lepton flavor universality violating $B\to K\ell\ell$ and $K^*\ell\ell$ decays tentatively observed by LHCb can be explained by leptoquark exchange. We explore a simple model for the $B$ anomalies with a composite leptoquark from new strong dynamics at the TeV scale, a confining SU($N_{\rm HC}$) hypercolor interaction. The new matter fields, fundamentals under SU($N_{\rm HC}$), are heavy vectorlike fermions $\Psi,\, S,$ and an inert scalar doublet $\phi$. $\Psi$ is colored under QCD while $S… 

B -physics anomalies: The bridge between R -parity violating supersymmetry and flavored dark matter

In recent years, significant experimental indications that point towards Lepton Flavour Universality violating effects in B-decays, involving $b \to c \tau \nu$ and $b \to s \ell^+ \ell^-$ have been

$B$ decay anomalies and dark matter from strong dynamics

Indications of lepton flavor universality violation in semileptonic $B$ decays to $K$ or $K^*$ and muons or electrons can be explained by leptoquark exchange. I present a model in which the

B anomalies and dark matter: a complex connection

We study an extension of the Standard Model that addresses the hints of lepton flavour universality violation observed in $$B\rightarrow K^{(*)} l^+l^-$$B→K(∗)l+l- decays at LHCb, while providing a

Anomalies in B -meson decays and the muon g−2 from dark loops

We explore a class of models which can provide a common origin for the recently observed evidence for lepton flavor universality violation in $b \to s l^+ l^- $ decays, the dark matter (DM) problem

Dark matter for b → sμ+μ− anomaly in a gauged U(1)X model

A bstractWe propose a new physics model which has a cold dark matter candidate and can explain the b → sμ+μ− anomaly at the same time. Our model includes a scalar quark q˜$$ \tilde{q} $$ and a scalar

Recent $$\varvec{B}$$B physics anomalies: a first hint for compositeness?

We scrutinize the recently further strengthened hints for new physics in semileptonic B-meson decays, focusing on the ‘clean’ ratios of branching fractions $$R_K$$RK and $$R_{K^*}$$RK∗ and examining

New Physics in $${\varvec{b \rightarrow s \ell ^+ \ell ^-}}$$ confronts new data on lepton universality

In light of the very recent updates on the $R_K$ and $R_{K^*}$ measurements from the LHCb and Belle collaborations, we systematically explore here imprints of New Physics in $b \to s \ell^+ \ell^- $

A connection between flavour anomaly, neutrino mass, and axion

We propose a minimal model in which the flavour anomaly in the $b \to s \mu^+ \mu^-$ transition is connected to the breaking of Peccei-Quinn (PQ) symmetry. The flavour anomaly is explained from new

B anomalies and leptoquarks at the LHC: Beyond the lepton-quark final state

Leptoquarks provide some of the simplest explanations to the hints of lepton flavor non-universality in $B$ decays. In particular, a new confining gauge group can provide a natural and appealing

Simultaneous interpretation of K and B anomalies in terms of chiral-flavorful vectors

A bstractWe address the presently reported significant flavor anomalies in the Kaon and B meson systems such as the CP violating Kaon decay (ϵ′/ϵ) and lepton-flavor universality violation in B meson



Hidden sector explanation of $B$-decay and cosmic ray anomalies

There are presently several discrepancies in $b \to s \ell^+ \ell^-$ decays of $B$ mesons suggesting new physics coupling to $b$ quarks and leptons. We show that a $Z'$, with couplings to quarks and

Scalar doublet models confront τ and b anomalies

There are indications of a possible breakdown of the standard model, suggesting that $\tau$ lepton interactions violate flavor universality. BABAR, Belle and LHCb report high ratios of $B\to

B decay anomalies from non-Abelian local horizontal symmetry

Recent anomalies in $B\to K^{(*)}\ell\ell$ meson decays are consistent with exchange of a heavy $Z'$ vector boson. Here we try to connect such new physics to understanding the origin of flavor, by

Lepton-Flavor-violating Z ′ using the electron-muon channel at the LHC

Inspired by the recent single $e^{\pm}\mu^{\mp}$ event at 2.1 TeV invariant mass from the ATLAS at $\sqrt{s}=13$ TeV with 3.2 fb$^{-1}$ luminosity, we propose an explanation using a $Z'$ gauge boson,

Lepton flavor universality violation without new sources of quark flavor violation

We show that new physics models without new flavor violating interactions can explain the recent anomalies in the $b\to s\ell^+\ell^-$ transitions. The $b\to s\ell^+\ell^-$ arises from a $Z'$ penguin

Constraints on a Z′ boson within minimal flavor violation

We explore a $Z^\prime$ boson coupled only with the Standard Model (SM) fermions ($Z^\prime f\bar{f}$) in the framework of Minimal Flavor Violation. We study its effects on the processes with lepton

Reconsidering the one leptoquark solution: flavor anomalies and neutrino mass

A bstractWe reconsider a model introducing a scalar leptoquark ϕ ∼ (3,1, −1/3) to explain recent deviations from the standard model in semileptonic B decays. The leptoquark can accommodate the

Interpreting hints for lepton flavor universality violation

We interpret the recent hints for lepton flavor universality violation in rare $B$ meson decays. Based on a model-independent effective Hamiltonian approach, we determine regions of new physics

LHCb anomaly and B physics in flavored Z ' models with flavored Higgs doublets

We study an extended Standard Model with a gauged U(1)$^{\prime}$ flavor symmetry, motivated not only by the fermion mass hierarchy but also by the excesses in $B \to K^{(*)} l l$ reported by the

Scrutinizing $R$-parity violating interactions in light of $R_{K^{(\ast)}}$ data

The LHCb has measured the ratios of $B\to K^\ast\mu^+\mu^-$ to $B\to K^\ast e^+ e^-$ branching fractions in two dilepton invariant mass squared bins, which deviate from the Standard Model predictions
