Query: Flavor Phenomenology of the Leptoquark Singlet-Triplet Model   In recent years, experiments revealed intriguing hints for new physics (NP)
in semi-leptonic $B$ decays. Both in charged current processes, involving $b
\to c \tau \nu$ transitions, and in the neutral currents $b\to s\ell^+\ell^-$,
a preference for NP compared to the standard model (SM) of more that $3\sigma$
and $5\sigma$ was found, respectively. In addition, there is the long-standing
tension between the theory prediction and the measurement of the anomalous
magnetic moment (AMM) of the muon ($a_\mu$) of more than $3\sigma$. Since all
these observables are related to the violation of lepton flavor universality
(LFU), a common NP explanation seems not only plausible but is even desirable.
In this context, leptoquarks (LQs) are especially promising since they give
tree-level effects in semi-leptonic $B$ decays, but only loop-suppressed
effects in other flavor observables that agree well with their SM predictions.
Furthermore, LQs can lead to a $m_t/m_\mu$ enhanced effect in $a_{\mu}$,
allowing for an explanation even with (multi) TeV particles. However, a single
scalar LQ representation cannot provide a common solution to all three
anomalies. In this article we therefore consider a model in which we combine
two scalar LQs: the $SU(2)_L$ singlet and the $SU(2)_L$ triplet. Within this
model we compute all relevant one-loop effects and perform a comprehensive
phenomenological analysis, pointing out various interesting correlations among
the observables. Furthermore, we identify benchmark points which are in fact
able to explain all three anomalies ($b \to c \tau \nu$, $b\to s\ell^+\ell^-$
and $a_\mu$), without violating bounds from other observables, and study their
predictions for future measurements.
