Deconstructing flavor anomalously
Javier Fuentes-Martín, Javier M. Lizana
Flavor deconstruction refers to ultraviolet completions of the Standard Model where the gauge group is split into multiple factors under which fermions transform non-universally. W…
Flavor hierarchies, flavor anomalies, and Higgs mass from a warped extra dimension
Javier Fuentes-Martin, Gino Isidori, Javier M. Lizana +2
The recent B-meson anomalies are coherently explained at the TeV scale by 4321 gauge models with hierarchical couplings reminiscent of the Standard Model Yukawas. We show that such…
Flavour non-universal Pati-Salam unification and neutrino masses
Julie Pagès
The B anomalies, by their distinctive flavour structure i.e. , bring a new piece to the long-standing flavour puzzle. The three-site flavour non-universal Pati-Salam (PS) m…
Reading the footprints of the B-meson flavor anomalies
Claudia Cornella, Darius A. Faroughy, Javier Fuentes-Martin +2
Motivated by the recent LHCb announcement of a violation of lepton-flavor universality in the ratio , we present an updated, comprehen…
Flavor Non-universal Pati-Salam Unification and Neutrino Masses
Javier Fuentes-Martin, Gino Isidori, Julie Pagès +1
We analyze the neutrino mass spectrum and discuss the extra-dimensional interpretation of a three-site Pati-Salam model which i) unifies all families of quark and leptons, ii) prov…
SuperTracer: A Calculator of Functional Supertraces for One-Loop EFT Matching
Javier Fuentes-Martin, Matthias König, Julie Pagès +2
We present SuperTracer, a Mathematica package aimed at facilitating the functional matching procedure for generic UV models. This package automates the most tedious parts of one-lo…
DsixTools 2.0: The Effective Field Theory Toolkit
Javier Fuentes-Martin, Pedro Ruiz-Femenia, Avelino Vicente +1

Vector Leptoquarks Beyond Tree Level III: Vector-like Fermions and Flavor-Changing Transitions
Javier Fuentes-Martin, Gino Isidori, Matthias König +1
Extending previous work on this subject, we evaluate the impact of vector-like fermions at next-to-leading order accuracy in models with a massive vector leptoquark embedded in the…
Vector Leptoquarks Beyond Tree Level II: Corrections and Radial Modes
Javier Fuentes-Martin, Gino Isidori, Matthias König +1
We clarify open issues in relating low- and high-energy observables, at next-to-leading order accuracy, in models with a massive leptoquark embedded in a flavor non-universal $SU(4…
Charm Physics Confronts High- Lepton Tails
Javier Fuentes-Martin, Admir Greljo, Jorge Martin Camalich +1
We present a systematic survey of possible short-distance new-physics effects in (semi)leptonic charged- and neutral-current charmed meson decays. Using the Standard Model Effectiv…
Third-family quark-lepton unification with a fundamental composite Higgs
Javier Fuentes-Martin, Peter Stangl
We present a model for third-family quark-lepton unification at the TeV scale featuring a composite Higgs sector. The model is based on a variant of the Pati-Salam model, the so-ca…
Vector Leptoquarks Beyond Tree Level
Javier Fuentes-Martin, Gino Isidori, Matthias König +1
Models with massive vector leptoquarks, resulting from an gauge symmetry spontaneously broken at the TeV scale, are of great phenomenological interest given the current "an…
Strong CP problem with low-energy emergent QCD: The 4321 case
Javier Fuentes-Martin, Mario Reig, Avelino Vicente
We analyze the strong CP problem and the implications for axion physics in the context of vector leptoquark models, recently put forward as an elegant solution to the hints o…
Revisiting the vector leptoquark explanation of the B-physics anomalies

Maximal Flavour Violation: a Cabibbo mechanism for leptoquarks
Luca Di Luzio, Javier Fuentes-Martin, Admir Greljo +2
We propose a mechanism that allows for sizeable flavour violation in quark-lepton currents, while suppressing flavour changing neutral currents in quark-quark and lepton-lepton sec…
