Continuum naturalness

Journal of High Energy Physics, 2019
We present a novel class of composite Higgs models in which the top and gauge partners responsible for cutting off the Higgs quadratic divergences form a continuum.

Clockwork neutrinos

Journal of High Energy Physics, 2019
Clockwork (CW) mechanism can explain the smallness of neutrino masses without introducing unnaturally small input parameters. In this paper we study the simplest CW neutrino model, the “uniform” clockwork, as well as a broader class of “generalized ...

Lorentzian Goldstone modes shared among photons and gravitons

European Physical Journal C: Particles and Fields, 2018
It has long been known that photons and gravitons may appear as vector and tensor Goldstone modes caused by spontaneous Lorentz invariance violation (SLIV). Usually this approach is considered for photons and gravitons separately. We develop the emergent

Application of quantum computing techniques in particle tracking at LHC [PDF]

EPJ Web of Conferences
After the next planned upgrades to the LHC, the luminosity it delivers will more than double, substantially increasing the already large demand on computing resources. Therefore an efficient way to reconstruct physical objects is required. Recent studies

Formation of Conserved Charge at the de Sitter Space

Particles, 2020
The article considers a new mechanism of charge accumulation in the early Universe in theories with compact extra dimensions. The relaxation processes in the extra space metric that take place during its formation lead to the establishment of symmetrical

A new method for the measurement of the Michel parameters that describe the daughter muon polarization in the τ − → μ − ν ¯ $$ \overline{\nu} $$ μ ν τ decay

Journal of High Energy Physics, 2022
This paper provides a detailed description of the method for the first direct measurement of all Michel parameters in the τ − → μ − ν ¯ $$ \overline{\nu} $$ μ ν τ decay related to the polarization of the daughter muon.

Nontrivial Isometric Embeddings for Flat Spaces

Universe, 2021
Nontrivial isometric embeddings for flat metrics (i.e., those which are not just planes in the ambient space) can serve as useful tools in the description of gravity in the embedding gravity approach.

Discovery reach for wino and higgsino dark matter with a disappearing track signature at a 100 TeV pp collider

European Physical Journal C: Particles and Fields, 2019
Within the theory of supersymmetry, the lightest neutralino is a dark matter candidate and is often assumed to be the lightest supersymmetric particle (LSP) as well.

On the Possible Asymmetry in Gamma Rays from Andromeda Due to Inverse Compton Scattering of Star Light on Electrons from Dark Matter Annihilation

Galaxies, 2023
Dark matter is a popular candidate to a new source of primary-charged particles, especially positrons in cosmic rays, which are proposed to account for observable anomalies.
