PASSAT: particle accelerator helioScopes for Slim Axion-like-particle deTection [PDF]

open access: yesThe European Physical Journal C, 2019
We propose a novel method to search for axion-like particles (ALPs) at particle accelerator experiments. ALPs produced at the target via the Primakoff effect subsequently enter a region with a magnetic field, where they are converted to photons that are ...

LHC signals of a heavy doublet Higgs as dark matter portal: cut-based approach and improvement with gradient boosting and neural networks

open access: yesJournal of High Energy Physics, 2019
Though the 125-GeV scalar, as the Higgs boson of the standard model, is disfavoured as a dark matter portal by direct searches and the observations on relic density, a heavier scalar in an extended electroweak sector can fit into that role.

Complex Langevin analysis of 2D U(1) gauge theory on a torus with a θ term

open access: yesJournal of High Energy Physics, 2020
Monte Carlo simulation of gauge theories with a θ term is known to be extremely difficult due to the sign problem. Recently there has been major progress in solving this problem based on the idea of complexifying dynamical variables. Here we consider the

The LHC magnetic field model [PDF]

open access: yes, 2005
The compensation of the field changes during the beam injection and acceleration in the LHC requires an accurate forecast and an active control of the magnetic field in the accelerator. The LHC Magnetic Field Model is the core of this magnetic prediction

Particle acceleration in binaries [PDF]

open access: yesEPJ Web of Conferences, 2017
Cygnus X-3 massive binary system is one of the powerful sources of radio and X-ray emission consisting of an accreting compact object, probably a black hole, with a Wolf-Rayet star companion. Based on the detections of ultra high energy gamma-rays by Kiel and Havera Park, Cygnus X-3 has been proposed to be one of the most powerful sources of charged ...

Extended scalar sectors, effective operators and observed data

open access: yesJournal of High Energy Physics, 2018
The available data on the 125 GeV scalar h is analysed to explore the room for new physics in the electroweak symmetry breaking sector. The first part of the study is model-independent, with h couplings to standard model particles scaled by quantities ...

Beam-Material Interaction [PDF]

open access: yes, 2016
Th is paper is motivated by the growing importance of better understanding of the phenomena and consequences of high- intensity energetic particle beam interactions with accelerator, generic target , and detector components.

Particle Acceleration Mechanisms

open access: yesSpace Science Reviews, 2008
We review the possible mechanisms for production of non-thermal electrons which are responsible for non-thermal radiation in clusters of galaxies. Our primary focus is on non-thermal Bremsstrahlung and inverse Compton scattering, that produce hard X-ray emission.

Recovery time of a plasma-wakefield accelerator [PDF]

open access: yesNature, 2022
The interaction of intense particle bunches with plasma can give rise to plasma wakes1,2 capable of sustaining gigavolt-per-metre electric fields3,4, which are orders of magnitude higher than provided by state-of-the-art radio-frequency technology5 ...
