Electroweak hadroproduction in the presence of heavy and bosons at NLO QCD in POWHEG
Mohammad Mahdi Altakach, Tomáš Ježo, Michael Klasen +2
We extend and improve upon our previous calculation of electroweak top-quark pair hadroproduction in extensions of the Standard Model with extra heavy neutral and charged spin-1 re…
Constraining new physics from Higgs measurements with Lilith-2
Marius Bertrand, Sabine Kraml, Tran Quang Loc +2
Lilith is a public Python library for constraining new physics from Higgs signal strength measurements. Version 2.0 of Lilith comes with an extensive XML database which includes th…
A combined explanation of the -meson decay anomalies with a single vector leptoquark
J. Kriewald, C. Hati, J. Orloff +1
Motivated by the recent experimental progress on the and anomalies in -decays, we consider an extension of the Standard Model by a single vecto…
OPE and quark-hadron duality for two-point functions of tetraquark currents in expansion
Wolfgang Lucha, Dmitri Melikhov, Hagop Sazdjian
We discuss the Operator Product Expansion (OPE) and quark-hadron duality for two-point Green functions of tetraquark currents. We emphasize that the factorizable part of the OPE se…
Higgs-mass predictions in the MSSM and beyond
P. Slavich, S. Heinemeyer, E. Bagnaschi +36
Predictions for the Higgs masses are a distinctive feature of supersymmetric extensions of the Standard Model, where they play a crucial role in constraining the parameter space. T…
Nonrelativistic Effective Field Theory with a Resonance Field
J. B. Habashi, S. Fleming, U. van Kolck
We discuss shallow resonances in the nonrelativistic scattering of two particles using an effective field theory (EFT) that includes an auxiliary field with the quantum numbers of…
