PT2GWFinder: A Package for Cosmological First-Order Phase Transitions and Gravitational Waves
Vedran Brdar, Marco Finetti, Marco Matteini +2
The detection of gravitational waves from binary black hole and neutron star mergers by ground-based interferometers, as well as the evidence for a gravitational wave background fr…
Long-lived Left-Right signals at the FCC-ee
Benjamin Fuks, Jonathan Kriewald, Miha Nemevšek +1
We give an extensive discussion of the displaced signals of heavy Majorana neutrino production at future electron-positron colliders operating at various proposed energies in the c…
Beautiful Majorana Higgses at Colliders
Benjamin Fuks, Jonathan Kriewald, Miha Nemevšek +1
We investigate a novel collider signature within the minimal Left-Right Symmetric Model, featuring a Higgs sector composed of a bi-doublet and two triplets. Our study focuses on a…
Functional Determinants for False Vacuum Decay
Pietro Baratella, Miha Nemevšek, Yutaro Shoji +2
We derive simple expressions to regularise functional determinants from fluctuations of fields with spin 0, 1/2, and 1. These are important for the precise dimensionful determinati…
False Vacuum Decay Rate From Thin To Thick Walls
Marco Matteini, Miha Nemevšek, Yutaro Shoji +1
We consider a single real scalar field in flat spacetime with a polynomial potential up to , that has a local minimum, the false vacuum, and a deeper global minimum, the true…
Hadron Collider Signatures of Lepton Number Violation in the Type II Seesaw Model
Patrick D. Bolton, Jonathan Kriewald, Miha Nemevšek +2
We examine the prospect of observing genuine lepton number violating (LNV) signals at hadron colliders in the context of the Type II seesaw mechanism. The model features smoking gu…
