Particle Acceleration Mechanisms
Space 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.

Journal of High Energy Physics, 2017 We consider two theoretical scenarios, each including a ℤ 2-odd sector and leading to an elementary dark matter candidate. The first one is a variant of the Type-III seesaw model where one lepton triplet is ℤ 2-odd, together with a heavy sterile neutrino.

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

Extended scalar sectors, effective operators and observed data
Journal 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 ...

Journal 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.

Conference on Lasers and Electro-Optics/International Quantum Electronics Conference, 2009 The production of highly energetic beams of both electrons and ions is a major part of the experimental programme at the Central Laser Facility (CLF), STFC Rutherford Appleton Laboratory. Every year sees a significant number of experiments done in both areas. This has been complemented by theoretical studies that have been carried out at the CLF and UK

Present Status of KEK Isotope Separation System
EPJ Web of Conferences, 2014 KISS (KEK Isotope Separation System) has been constructed at Nishina Re-search Center (NRC) of RIKEN to study the decay properties of heavy neutron-rich iso-topes with mass number around A∼200 along the neutron magic number of N = 126 for the ...

Machine Protection and Interlock Systems for Circular Machines - Example for LHC [PDF]
, 2016 This paper introduces the protection of circular particle accelerators from accidental beam losses. Already the energy stored in the beams for accelerators such as the TEVATRON at Fermilab and Super Proton Synchrotron (SPS) at CERN could cause serious ...

A Symplectic Multi-Particle Tracking Model for Self-Consistent Space-Charge Simulation
, 2016 Symplectic tracking is important in accelerator beam dynamics simulation. So far, to the best of our knowledge, there is no self-consistent symplectic space-charge tracking model available in the accelerator community.
