Resonant Di-Higgs Searches in at HL-LHC: Supersymmetry versus Compositeness Benchmarks
Atri Dey, Carl Johan Konigsson, Stefano Moretti +3
We explore the scope of the High-Luminosity Large Hadron Collider (HL-LHC) in testing Standard Model (SM) di-Higgs production and decay into final states in the context of t…
Thermal Masses and Bubble-Wall Friction in Cosmological Phase Transitions
Carlo Branchina, Stefania De Curtis, Luigi Delle Rose +3
Bubble-wall friction controls the dynamics of first-order cosmological phase transitions. In Boltzmann-equation approaches, a major uncertainty arises from infrared gauge bosons, w…

First order phase transitions could play a major role in the early universe, providing important phenomenological consequences, such as the production of gravitational waves and th…
Spin-1 resonances
Stefania De Curtis, Daniele Dominici
Spin-1 resonances are naturally present in composite Higgs frameworks. We first review a model independent approach to parametrize a single additional heavy triplet and then we con…
Precision from the diphoton Zh channel at FCC-hh
Fady Bishara, Stefania De Curtis, Luigi Delle Rose +5
The future 100 TeV FCC-hh hadron collider will give access to rare but clean final states which are out of reach of the HL-LHC. One such process is the production channel in t…
