Matrix element method at NLO: A fine proof of concept in POWHEG
Ulrich Haisch, Jakob Linder, Luc Schnell +2
The matrix element method (MEM) provides a fully probabilistic approach to confront experimental events with theory, retaining all correlations in the scattering matrix element. Wh…
Precision tests of third-generation four-quark operators: one- and two-loop matching
Ulrich Haisch, Luc Schnell
We calculate the one- and two-loop matching corrections in the Standard Model effective field theory (SMEFT) that impact electroweak precision measurements and flavour physics obse…
SMEFT at NNLOPS: production
Rhorry Gauld, Ulrich Haisch, Luc Schnell
In the context of the Standard Model effective field theory (SMEFT) the next-to-next-to-leading (NNLO) QCD corrections to the Higgsstrahlungs () processes in hadronic collision…
LHC tau-pair production constraints on and
Ulrich Haisch, Luc Schnell, Joachim Weiss
We point out that relevant constraints on the anomalous magnetic () and electric () moment of the tau lepton can be derived from tau-pair production measurements performe…
Long-lived particle phenomenology in the 2HDM+ model
Ulrich Haisch, Luc Schnell
Higgs decays displaced from the primary interaction vertex represent a striking experimental signature that is actively searched for by the ATLAS, CMS and LHCb collaborations. We p…
Drell-Yan production in third-generation gauge vector leptoquark models at NLO+PS in QCD
Ulrich Haisch, Luc Schnell, Stefan Schulte
Motivated by the long-standing hints of lepton-flavour non-universality in the and channels, we study Drell-Yan ditau production at the Lar…
On Drell-Yan production of scalar leptoquarks coupling to heavy-quark flavours
Ulrich Haisch, Luc Schnell, Stefan Schulte
Given the hints of lepton-flavour non-universality in semi-leptonic decays, leptoquark (LQ) models with sizeable couplings to heavy-quark flavours are enjoying a renaissance. W…
Explaining the hints for lepton flavour universality violation with three leptoquark generations
Andreas Crivellin, Benjamin Fuks, Luc Schnell
Leptoquarks are prime candidates for explaining the intriguing hints for lepton flavour universality violation. In particular, the doublet of scalar leptoquarks is…
Unveiling Hidden Physics at the LHC
Oliver Fischer, Bruce Mellado, Stefan Antusch +30
The field of particle physics is at the crossroads. The discovery of a Higgs-like boson completed the Standard Model (SM), but the lacking observation of convincing resonances Beyo…
First-Generation New Physics in Simplified Models: From Low-Energy Parity Violation to the LHC
Andreas Crivellin, Martin Hoferichter, Matthew Kirk +2
New-physics (NP) constraints on first-generation quark-lepton interactions are particularly interesting given the large number of complementary processes and observables that have…
Complete Lagrangian and Set of Feynman Rules for Scalar Leptoquarks
Andreas Crivellin, Luc Schnell
Leptoquarks (LQs) have attracted increasing attention within recent years, mainly since they can explain the flavor anomalies found in , …
Addendum to: Combined Constraints on First Generation Leptoquarks
Andreas Crivellin, Luc Schnell
In this addendum to arXiv:2101.07811 we discuss the implications of the recent CMS analysis of lepton flavour universality violation in non-resonant di-lepton pairs for first gener…
Combined Constraints on First Generation Leptoquarks
Andreas Crivellin, Dario Müller, Luc Schnell
In this article we perform a combined analysis of low energy precision constraints and LHC searches for leptoquarks which couple to first generation fermions. Considering all ten l…
