The continuum dark matter zoo

Journal of High Energy Physics, 2023
We generalize the recently proposed continuum dark matter model to the case where the dark matter consists of a spin-1/2 or spin-1 gapped continuum. We construct simple continuum analogs of weakly interacting massive particles annihilating through the Z ...

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.

Elementary particles as elementary particles

Annals of Physics, 1965
Abstract The Z = 0 rule is investigated within a general field theoretic formulation. It is shown that the equivalence of a system with an elementary particle of vanishing wave function renormalization to a direct interaction theory is intimately related to the divergence of the bare mass and the consequent degeneration of the equations of motion ...

CASCADE3 A Monte Carlo event generator based on TMDs

European Physical Journal C: Particles and Fields, 2021
The Cascade3 Monte Carlo event generator based on Transverse Momentum Dependent (TMD) parton densities is described. Hard processes which are generated in collinear factorization with LO multileg or NLO parton level generators are extended by adding ...

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

Forbidden conformal dark matter at a GeV

Journal of High Energy Physics, 2023
We introduce a model of dark matter (DM) where the DM is a composite of a spontaneously broken conformal field theory. The DM is a thermal relic with its abundance determined by the freeze-out of annihilations to dilatons, the Goldstone boson of broken ...

Integration and Commissioning of the Software-based Readout System for ATLAS Level-1 Endcap Muon Trigger in Run 3 [PDF]

EPJ Web of Conferences, 2021
The Large Hadron Collider and the ATLAS experiment at CERN will explore new frontiers in physics in Run 3 starting in 2022. In the Run 3 ATLAS Level-1 endcap muon trigger, new detectors called New Small Wheel and additional Resistive Plate Chambers will ...

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.
