Cornering variants of Georgi-Machacek model using Higgs precision data

Dipankar Das, Ipsita Saha

We show that in the absence of trilinear terms in the scalar potential of Georgi-Machacek model, heavy charged scalars do not necessarily decouple from the decay amplitu…

Exclusive heavy quark-pair production in ultraperipheral collisions

Mateus Reinke Pelicer, Emmanuel G. de Oliveira, Roman Pasechnik

In this article, we study the fully differential observables of exclusive production of heavy (charm and bottom) quark pairs in high-energy ultraperipheral and collisions…

Probing Trans-electroweak First Order Phase Transitions from Gravitational Waves

Andrea Addazi, Antonino Marciano, Roman Pasechnik

We propose direct tests of very high energy first-order phase transitions, which are elusive to collider physics, deploying the gravitational waves measurements. We show that first…

Model-independent femtoscopic Levy imaging for elastic proton-proton scattering

T. Csorgo, R. Pasechnik, A. Ster

A model independent Levy expansion method is introduced to describe nearly Levy shaped squared moduli of Fourier transforms. We apply this method to precisely characterize the most…

Parton Shower and Matching Uncertainties in Top Quark Pair Production with Herwig 7

Kyle Cormier, Simon Plätzer, Christian Reuschle +2

We evaluate the theoretical uncertainties in next-to-leading order plus parton shower predictions for top quark pair production and decay in hadronic collisions. Our work is carrie…
