A thermal neutrino interaction rate at NLO
The interaction rate of an ultrarelativistic active neutrino at a temperature below the electroweak crossover plays a role in leptogenesis scenarios based on oscillations between active neutrinos and GeV-scale sterile neutrinos.

Abstract Short‐lived, unobservable, and not subject to the usual rules of conservation of energy and momentum, virtual particles—an integral part of the conceptual framework of quantum field theory (QFT)—exhibit a number of curious characteristics which, in recent decades, have in part fueled important discussions about their ontological status ...

The electroweak phase transition: a collider target
Determining the thermal history of electroweak symmetry breaking (EWSB) is an important challenge for particle physics and cosmology. Lattice simulations indicate that EWSB in the Standard Model (SM) occurs through a crossover transition, while the ...

Two Micron‐Size Dark Dimensions
Abstract Two extra dimensions of micron scale might simultaneously address the gauge and cosmological hierarchy problems. In this paper various observational bounds in scenarios with one and two large extra dimensions are examined, to see if they are compatible with the micron scale.

Application of Fermion Quantum Number F and Unit Electroweak Charge F0 in the Electroweak Theory
After hypercharge $Y$, isospin $I$, isospin projection $I_3$, and four flavour quantum numbers ($S$, $C$, $B^*$ and $T$), weak isospin $I_{w3}$ and weak hypercharge $Y_w$ in the electroweak theory are substituted by fermion quantum number $F$ and unit ...

Simulation of a Three‐Nucleons System Transition on Quantum Circuits
A general procedure is presented to calculate the transition probability for two nuclear states and a transition operator. The ground state is approximated through the variational quantum eigensolver and the first excited one using more sophisticated variational algorithms.

Jets and Vector Bosons in Heavy Ion Collisions
This paper reviews experimental results on jets and electroweak boson (photon,Wand Z) production in heavy-ion collisions, from the CMS and ATLAS detectors, using data collected during 2011 PbPb run and pp data collected at an equivalent energy.

Higgs Boson studies at future particle colliders
This document aims to provide an assessment of the potential of future colliding beam facilities to perform Higgs boson studies. The analysis builds on the submissions made by the proponents of future colliders to the European Strategy Update process ...

Dark Dimension With (Little) Strings Attached
Abstract A relation between dark energy and the scale of new physics in weakly coupled string theory is motivated. This mixing between infrared and ultraviolet physics leads to a unique corner for real‐world phenomenology: barring fine‐tunings, the authors are naturally led to the “dark dimension” scenario, a single mesoscopic extra dimension of micron
