Precise measurements of $$b\rightarrow c\tau \bar{\nu }$$ b → c τ ν ¯ decays require large resource-intensive Monte Carlo (MC) samples, which incorporate detailed simulations of detector responses and physics backgrounds. Extracted parameters may be highly sensitive to the underlying theoretical models used in the MC generation. Because new physics (NP) can alter decay distributions and acceptances, the standard practice of fitting NP Wilson coefficients to SM-based… 

The role of right-handed neutrinos in $$ b\to c\tau \overline{v} $$ anomalies

Motivated by the persistent anomalies reported in the $$ b\to c\tau \overline{v} $$ data, we perform a general model-independent analysis of these transitions, in the presence of light

Challenges in semileptonic $${\varvec{B}}$$ decays

Two of the elements of the Cabibbo–Kobayashi–Maskawa quark mixing matrix, $$|V_{ub}|$$ and $$|V_{cb}|$$ , are extracted from semileptonic B decays. The results of the B factories, analysed in

Clustering of $\bar B\to D^{(*)}\tau^-\bar\nu_\tau$ kinematic distributions with ClusterKinG.

New Physics can manifest itself in kinematic distributions of particle decays. The parameter space defining the shape of such distributions can be large which is challenging for both theoretical and

Complete framework for tau polarimetry in B→D(*)τν decays

The meson decays B → D τν and B → D (cid:2) τν are sensitive probes of the b → c τν transition. In this work, we present a complete framework to obtain the maximum information on the physics of B → D

Relations between b → cτν decay modes in scalar models

As a consequence of the Ward identity for hadronic matrix elements, we find relations between the differential decay rates of semileptonic decay modes with the underlying quark-level transition

Reinterpretation of LHC Results for New Physics: Status and recommendations after Run 2

We report on the status of efforts to improve the reinterpretation of searches and measurements at the LHC in terms of models for new physics, in the context of the LHC Reinterpretation Forum. We

Unified explanation of flavor anomalies, radiative neutrino masses, and ANITA anomalous events in a vector leptoquark model

Driven by the recent experimental hints of lepton-flavor-universality violation in the bottom-quark sector, we consider a simple extension of the Standard Model (SM) with an additional vector

Unified framework for B-anomalies, muon g − 2 and neutrino masses

We present a model of radiative neutrino masses which also resolves anomalies reported in $B$-meson decays, $R_{D^{(\star)}}$ and $R_{K^{(\star)}}$, as well as in muon $g-2$ measurement, $\Delta

RooHammerModel: interfacing the HAMMER software tool with the HistFactory package

The methods developed in the construction of RooHammerModel can provide specific information for alternative future attempts to interface HAMMER with other data-fitting frameworks, as well as validation and performance studies of the interface.



Semileptonic B Decays as a Probe of New Physics

Physics beyond the Standard Model could be measured indirectly, through its effects on Standard Model observables. One place to look for such effects is in the semileptonic decays of B mesons. In

HAMMER: Reweighting tool for simulated data samples

Modern flavour physics experiments, such as Belle II or LHCb, require large samples of generated Monte Carlo events. Monte Carlo events often are processed in a sophisticated chain that includes a

Anatomy of b → c τ ν anomalies

A bstractIn recent times, one of the strongest hints of Physics Beyond the Standard Model (BSM) has been the anomaly in the ratios RD and RD*$$ {R}_{D^{*}} $$ measured in the charged current decays

We develop a rigorous, semi-analytical method for maximizing any $b\to c\tau\nu$ observable in the full 20-real-dimensional parameter space of the dimension 6 effective Hamiltonian, given some fixed

B-physics anomalies: a guide to combined explanations

A bstractMotivated by additional experimental hints of Lepton Flavour Universality violation in B decays, both in charged- and in neutral-current processes, we analyse the ingredients necessary to

A global likelihood for precision constraints and flavour anomalies

We present a global likelihood function in the space of dimension-six Wilson coefficients in the Standard Model Effective Field Theory. The likelihood includes contributions from flavour-changing

Resonance chiral Lagrangian currents and $\tau$ decay Monte Carlo

In the present paper we describe the set of form factors for hadronic τ decays based on Resonance Chiral Theory. The technical implementation of the form factors in FORTRAN code is also explained. It

Model-independent description of B ---> pi l nu decays and a determination of |V(ub)|

We propose a new parametrization of the B → π vector form factor f + (q 2 ) as an expansion in powers of a conformal mapping variable, which satisfies unitarity, analyticity and perturbative QCD
