On phase-space integrals with Heaviside functions

Journal of High Energy Physics, 2022
We discuss peculiarities that arise in the computation of real-emission contributions to observables that contain Heaviside functions. A prominent example of such a case is the zero-jettiness soft function in SCET, whose calculation at next-to-next-to ...

Theoretical Particle Physics [PDF]

Reviews of Modern Physics, 1999
“Gentlemen and Fellow Physicists of America: We meet today on an occasion which marks an epoch in the history of physics in America; may the future show that it also marks an epoch in the history of the science which this Society is organized to cultivate!” (Rowland, 1899).1 These are the opening words of the address by Henry Rowland, the first ...

Probing the gluon plasma with charm balance functions

European Physical Journal C: Particles and Fields, 2021
Recent theoretical explanations for how hydrodynamic-like flow can build up quickly in small collision systems (hydrodynamization) has led to a microscopic picture of flow building up in a gluon-dominated phase before chemical equilibrium between quarks ...

Higgs squared

Journal of High Energy Physics, 2023
We present a novel construction for a Higgs-VEV sensitive (HVS) operator, which can be used as a trigger operator in cosmic selection models for the electroweak hierarchy problem.

Bosonization in Particle Physics [PDF]

, 1997
Path integral techniques in collective fields are shown to be a useful analytical tool to reformulate a field theory defined in terms of microscopic quark (gluon) degrees of freedom as an effective theory of collective boson (meson) fields.

Towards the ultimate differential SMEFT analysis

Journal of High Energy Physics, 2020
We obtain SMEFT bounds using an approach that utilises the complete multi-dimensional differential information of a process. This approach is based on the fact that at a given EFT order, the full angular distribution in the most important electroweak ...

Cosmology and New Physics [PDF]

, 2006
A comparison of the standard models in particle physics and in cosmology demonstrates that they are not compatible, though both are well established. Basics of modern cosmology are briefly reviewed.

Parity doubling in particle physics [PDF]

, 2007
Parity doubling in excited hadrons is reviewed. Parity degeneracy in hadrons was first experimentally observed 40 years ago. Recently new experimental data on light mesons caused much excitement and renewed interest to the phenomenon, which still remains
