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.

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 ...

Next-to-leading power threshold effects for inclusive and exclusive processes with final state jets
Journal of High Energy Physics, 2020 It is well known that cross-sections in perturbative QCD receive large corrections from soft and collinear radiation, which can be resummed to all orders in the coupling.

Perspectives of High Energy Neutrino Astronomy [PDF]
, 2006 This work discusses the perspectives to observe fluxes of high energy astrophysical neutrinos with the planned km3 telescopes. On the basis of the observations of GeV and TeV gamma-rays, and of ultra high energy cosmic rays, it is possible to construct ...

Multi-messenger astronomy with very-high-energy gamma-ray observations [PDF]
Journal of Physics: Conference Series, 2019 After decades of development, multi-messenger astronomy, the combination of information on cosmic sources from photons, neutrinos, charged particles and gravitational waves, is now an established reality.

An analytic analysis of the pion decay constant in three-flavoured chiral perturbation theory
European Physical Journal C: Particles and Fields, 2017 A representation of the two-loop contribution to the pion decay constant in SU(3) chiral perturbation theory is presented. The result is analytic up to the contribution of the three (different) mass sunset integrals, for which an expansion in their ...

High-Energy Neutrino Astronomy: Current Status and Prospects [PDF]
Proceedings of European Physical Society Conference on High Energy Physics — PoS(EPS-HEP2019), 2019 In the last decade, neutrino astronomy has taken off with two major breakthroughs, the first observation of high-energy astrophysical neutrinos in 2013 and the first evidence for gamma-rays and neutrinos from a single object published in summer 2018.

The Phenomena of High Energy Astrophysics [PDF]
, 2003 A brief summary of some highlights in the study of high energy astrophysical sources over the past decade is presented. It is argued that the great progress that has been made derives largely from the application of new technology to observation ...

Ground-based detectors in very-high-energy gamma-ray astronomy [PDF]
, 2015 Following the discovery of the cosmic rays by Victor Hess in 1912, more than 70 years and numerous technological developments were needed before an unambiguous detection of the first very-high-energy gamma-ray source in 1989 was made.
