TAIGA - an innovative hybrid array for high energy gamma astronomy, cosmic ray physics and astroparticle physics

, 2021
The physics motivations and advantages of the hybrid detector complex TAIGA are presented. TAIGA aims to address gamma-ray astronomy at energies from a few TeV to several PeV units, as well as cosmic-ray physics from 100 TeV to several EeV units and ...

Clash of the titans: ultra-high energy KM3NeT event versus IceCube data

Physics Letters B
KM3NeT has reported the detection of a remarkably high-energy through-going muon. Lighting up about a third of the detector, this muon likely originated from a neutrino exceeding 10 PeV in energy.

Gravitational wave signatures from domain wall and strong first-order phase transitions in a two complex scalar extension of the Standard Model

Journal of High Energy Physics, 2021
We consider a simple extension of Standard Model by adding two complex singlet scalars with a U(1) symmetry. A discrete Z 2 × Z 2 ′ $$ {\mathcal{Z}}_2\times {\mathcal{Z}}_2^{\prime } $$ symmetry is imposed in the model and the added scalars acquire a non

Stochastic analysis of ultrahigh-energy cosmic ray interactions

Astronomy & Astrophysics
Context. Photonuclear interactions between ultrahigh-energy cosmic ray (UHECR) nuclei and photon fields are key to connecting the compositions observed at Earth to those emitted from the sources as well as understanding their evolution during propagation.

Addressing the high-f problem in pseudo-Nambu–Goldstone boson dark energy models with dark matter–dark energy interaction

European Physical Journal C: Particles and Fields, 2020
We consider a dark energy scenario driven by a scalar field $$\phi $$ ϕ with a pseudo-Nambu–Goldstone boson (pNGB) type potential $$V(\phi )=\mu ^4 \left( 1+ \mathrm{cos}(\phi /f) \right) $$ V ( ϕ ) = μ 4 1 + cos ( ϕ / f ) .
