Next-to-leading-order QCD Corrections to Higgs Production in association with a Jet

R. Bonciani, V. Del Duca, H. Frellesvig +6

We compute the next-to-leading-order (NLO) QCD corrections to the Higgs pT distribution in Higgs production in association with a jet via gluon fusion at the LHC, with exact depend…

Anatomy of kaon decays and prospects for lepton flavour universality violation

G. D'Ambrosio, A. M. Iyer, F. Mahmoudi +1

The kaon sector is characterised by several processes which are under active investigation across different experiments. In this work, we present the global picture that emerges fr…

The W boson mass weighs in on the non-standard Higgs

Giacomo Cacciapaglia, Francesco Sannino

We consider the implications of the CDF collaboration high-precision measurement of the W boson mass on models with a non-standard Higgs. We show that this requires an enhancement…

Neutrino Self-Interactions: A White Paper

Jeffrey M. Berryman, Nikita Blinov, Vedran Brdar +31

Neutrinos are the Standard Model (SM) particles which we understand the least, often due to how weakly they interact with the other SM particles. Beyond this, very little is known…

Electron scattering of light new particles from evaporating primordial black holes

Roberta Calabrese, Marco Chianese, Damiano F. G. Fiorillo +1

Primordial black holes are a possible component of dark matter, and a most promising way of investigating them is through the product of their Hawking evaporation. As a result of t…

Axion signatures from supernova explosions through the nucleon electric-dipole portal

Giuseppe Lucente, Leonardo Mastrototaro, Pierluca Carenza +3

We consider axions coupled to nucleons and photons only through the nucleon electric-dipole moment (EDM) portal. This coupling is a model-independent feature of QCD axions, which s…
