High-energy gamma-ray astronomy [PDF]
Physics Today, 1975 All the natural electromagnetic radiation reaching the Earth, whether from nearby or remote parts of the universe, brings with it information on the contents or structure of the region in which it originated. This is true of each part of the spectrum, from radio waves through the visible, ultraviolet and x-ray regions, to the realm of high-energy gamma

Distributed training and scalability for the particle clustering method UCluster [PDF]
EPJ Web of Conferences, 2021 In recent years, machine-learning methods have become increasingly important for the experiments at the Large Hadron Collider (LHC). They are utilised in everything from trigger systems to reconstruction and data analysis. The recent UCluster method is a

Journal of High Energy Physics, 2022 We propose a new mechanism where a multi-component dark sector generates the observed dark matter abundance and baryon asymmetry and thus addresses the coincidence between the two.

Monte Carlo study of particle identification at the CEPC using TPC dE / dx information
European Physical Journal C: Particles and Fields, 2018 The kaon identification is crucial for the flavor physics, and also benefits the flavor and charge reconstruction of the jets. We explore the particle identification capability for tracks with momenta ranging from 2–20 GeV/c using the dE / dx ...

Measurements of UHECR Mass Composition by Telescope Array [PDF]
EPJ Web of Conferences, 2019 Telescope Array (TA) has recently published results of nearly nine years of Xmax observations providing its highest statistics measurement of ultra high energy cosmic ray (UHECR) mass composition to date for energies exceeding 1018.2 eV.

Towards high-energy neutrino astronomy [PDF]
The European Physical Journal H, 2012 The search for the sources of cosmic rays is a three-fold assault, using charged cosmic rays, gamma rays and neutrinos. The first conceptual ideas to detect high energy neutrinos date back to the late fifties. The long evolution towards detectors with a realistic discovery potential started in the seventies and eighties, with the pioneering works in ...

Universal relations in composite Higgs models
Journal of High Energy Physics, 2019 We initiate a phenomenological study of “universal relations” in composite Higgs models, which are dictated by nonlinear shift symmetries acting on the 125 GeV Higgs boson.

High energy neutrino astronomy
Comptes Rendus. Physique, 2005 Traditionally photons are used to study the Universe, but, at high energies, absorption of photons renders it opaque. Neutrinos, interacting only weakly, are good alternative candidates to probe the high energy Universe over cosmological distances. Pioneering experiments utilizing the neutrino as messenger have been taking data for about a decade, but ...

Depth of maximum of air-shower profiles: testing the compatibility of measurements performed at the Pierre Auger Observatory and the Telescope Array experiment [PDF]
EPJ Web of Conferences, 2019 At the Pierre Auger Observatory and the Telescope Array, the measurements of depths of maximum of airshower profiles, Xmax, are performed using direct observations of the longitudinal development of showers with the help of the fluorescence telescopes ...
