The striking success of the Standard Model in explaining precision data and, at the same time, its lack of explanations for various fundamental phenomena, such as dark matter or the baryon asymmetry of the universe, suggests new physics at…

A Proof of Concept for Matchete: An Automated Tool for Matching Effective Theories Open
Studying the impact of new-physics models on low-energy observables necessitates matching to effective field theories at the relevant mass thresholds. We introduce the first public version of Matchete, a computer tool for matching weakly-c…

Combining low- and high-energy constraints on flavourful EFTs Open
The study of high-pT tails at the LHC can be a complementary probe to low-energy observables when investigating the flavour structure of the Standard Model and its extensions.\nMotivated by the B anomalies, we study the interplay between l…

Probing Flavor in semileptonic transitions at High-$p_T$ Open
The Drell-Yan processes $pp\\to\\ell\\nu$ and $pp\\to\\ell\\ell$ at high transverse momentum can provide important probes of semileptonic transitions that are complementary to low-energy flavor physics observables. We parametrize possible …

Evanescent Operators in One-Loop Matching Computations Open
Effective Field Theory calculations used in countless phenomenological analyses employ dimensional regularization, and at intermediate stages of computations, the operator bases extend beyond the four-dimensional ones. The extra pieces -- …

Confronting the vector leptoquark hypothesis with new low- and high-energy data Open
In light of new data we present an updated phenomenological analysis of the simplified $U_1$-leptoquark model addressing charged-current $B$-meson anomalies. The analysis shows a good compatibility of low-energy data (dominated by the lept…

Towards matching effective theories efficiently Open
Separation of scales in quantum field theories is essential when studying the low-energy phenomenology of a given UV model. To this end, it is necessary to construct an effective field theory containing only the light degrees of freedom an…

Drell-Yan Tails Beyond the Standard Model Open
We investigate the high-$p_T$ tails of the $pp\to \ell ν$ and $pp \to \ell \ell$ Drell-Yan processes as probes of New Physics in semileptonic interactions with an arbitrary flavor structure. For this purpose, we provide a general decomposi…

HighPT: A Tool for high-$p_T$ Drell-Yan Tails Beyond the Standard Model Open
HighPT is a Mathematica package for the analysis of high-energy data of semileptonic transitions at hadron colliders. It allows to compute high-$p_T$ tail observables for semileptonic processes, i.e. Drell-Yan cross sections, for dilepton …

Flavour alignment of New Physics in light of the (g − 2)μ anomaly Open
A bstract We investigate the flavour alignment conditions that New Physics (NP) models need to satisfy in order to address the ( g − 2) μ anomaly and, at the same time, be consistent with the tight bounds from μ → eγ and τ → μγ . We analys…

Flavor alignment of New Physics in light of the $(g-2)_μ$ anomaly Open
Addressing the ${(g-2)_μ}$ anomaly and simultaneously being consistent with the tight bounds on ${μ\to e γ}$ requires a precise alignment of the lepton dipole operator in flavor space. We investigate this alignment condition in the Standar…
