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 nonuniversal SU(4)×SU(3)×SU(2)×U(1) gauge group. Extending previous work on this subject, we present a complete analysis of the O(αs) corrections to the matching conditions of semileptonic operators at the high scale. These corrections are not negligible, but they do not exceed the 10% level and are subleading compared to the O(α4…

Vector leptoquarks beyond tree level. III. Vectorlike fermions and flavor-changing transitions

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 $SU(4)\times

Lepton-quark fusion at Hadron colliders, precisely

When a TeV-scale leptoquark has a sizeable Yukawa coupling, its dominant production mechanism at hadron colliders is the partonic-level lepton-quark fusion. Even though the parton distribution

Low-energy phenomenology of scalar leptoquarks at one-loop accuracy

We perform a complete study of the low-energy phenomenology of S 1 and S 3 leptoquarks, aimed at addressing the observed deviations in B -meson decays and the muon magnetic dipole moment. Leptoquark

Reading the footprints of the B-meson flavor anomalies

Motivated by the recent LHCb announcement of a 3.1σ violation of lepton- flavor universality in the ratio RK = Γ(B → Kμ+μ−)/Γ(B → Ke+e−), we present an updated, comprehensive analysis of the flavor

Non-universal gauge interactions addressing the inescapable link between Higgs and Flavour

We systematically explore ultraviolet complete models where flavour hierarchies emerge, via approximate accidental symmetries, from an underlying flavour non-universal gauge structure. In order to

We perform a comprehensive phenomenological analysis of the twin Pati-Salam theory of flavour, focussing on the parameter space relevant for interpreting the B-anomalies via vector leptoquark U1

Third-Family Quark-Lepton Unification and Electroweak Precision Tests

We analyze the compatibility of the hypothesis of third-family quark-lepton unification at the TeV scale with electroweak precision data, lepton flavor universality tests, and high-$p_T$ constraints.

Drell-Yan production in third-generation gauge vector leptoquark models at NLO+PS in QCD

Motivated by the long-standing hints of lepton-flavour non-universality in the b → cℓν and b → sℓ+ℓ− channels, we study Drell-Yan ditau production at the Large Hadron Collider (LHC). In the context

The Standard Model (SM) does not contain by definition any new physics (NP) contributions to any observable but contains four CKM parameters which are not predicted by this model. We point out that



Vector leptoquarks beyond tree level

Models with massive vector leptoquarks, resulting from an SU(4) gauge symmetry spontaneously broken at the TeV scale, are of great phenomenological interest given the current “anomalies” in

Left-right SU(4) vector leptoquark model for flavor anomalies

QCD improved matching for semileptonic B decays with leptoquarks

Leptoquarks (LQs) provide very promising solutions to the tensions between the experimental measurements and the SM predictions of b→sl+l− and b→cτν processes. In this case the LQ masses are in

Model of vector leptoquarks in view of the B -physics anomalies

Lepton number as a fourth color is an intriguing theoretical idea which is combined with a possible left-right symmetry within the famous Pati-Salam (PS) model. In the conventional PS model, a

There are four models of tree-level new physics (NP) that can potentially simultaneously explain the $b \to s \mu^+ \mu^-$ and $b \to c \tau^- {\bar\nu}$ anomalies. They are the S3, U3 and U1

We present a detailed analysis of the collider signatures of TeV-scale massive vector bosons motivated by the hints of lepton flavour non-universality observed in B-meson decays. We analyse three

B Meson Anomalies in a Pati-Salam Model within the Randall-Sundrum Background.

The phenomenology of this model is considered in the context of the hints for lepton flavor universality violation in semileptonic B decays, and it is found that in b→sℓ^{+}⅓^{-} transitions, the observed deviations from the standard model predictions can be explained with natural values for the free parameters of the model.
