Search for periodic signals in the dielectron and diphoton invariant mass spectra using 139 fb −1 of pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2023
A search for physics beyond the Standard Model inducing periodic signals in the dielectron and diphoton invariant mass spectra is presented using 139 fb −1 of s $$ \sqrt{s} $$ = 13 TeV pp collision data collected by the ATLAS experiment at the LHC. Novel

Natural Qubit Matrix of Primary Elements of Matter

open access: yesMATEC Web of Conferences, 2018
The arithmetic limits of natural bit calculations are strictly established. The natural quantum metric system has been developed. Only seven scaling units that generate thirteen invariant values are necessary and sufficient for an accurate estimation and

Takagi Topological Insulator on the Honeycomb Lattice

open access: yesFrontiers in Physics, 2022
Recently, real topological phases protected by PT symmetry have been actively investigated. In two dimensions, the corresponding topological invariant is the Stiefel-Whitney number.

Invariant mass reconstruction of heavy gauge bosons decaying to $$\tau $$ τ leptons using machine learning techniques

open access: yesEuropean Physical Journal C: Particles and Fields
Many analyses are performed by the LHC experiments to search for heavy gauge bosons, which appear in several new physics models. The invariant mass reconstruction of heavy gauge bosons is difficult when they decay to $$\tau $$ τ leptons due to missing ...

Hadronic uncertainties in B → K ∗ μ + μ −: a state-of-the-art analysis

open access: yesJournal of High Energy Physics, 2017
In the absence of direct evidence for New Physics at present LHC energies, the focus is set on the anomalies and discrepancies recently observed in rare b → sℓℓ transitions which can be interpreted as indirect hints.

Scale-invariant dynamical fluctuations in jet physics [PDF]

open access: yesThe European Physical Journal C, 1999
An interpretation of scale-invariant multiplicity fluctuations inside hadronic jets is presented. It is based on the branching mechanism with the angular ordering of soft partons in sequential branchings. A relationship with fractal distributions is demonstrated.

Symmetries and invariants of the oscillator and envelope equations with time-dependent frequency

open access: yesPhysical Review Special Topics. Accelerators and Beams, 2006
The single-particle dynamics in a time-dependent focusing field is examined. The existence of the Courant-Snyder invariant, a fundamental concept in accelerator physics, is fundamentally a result of the corresponding symmetry admitted by the harmonic ...

NEUTRINO PHYSICS AND LEPTONIC WEAK BASIS INVARIANTS [PDF]

open access: yesParticle Physics at the Silver Jubilee of Lomonosov Conferences, 2019
In this talk we present a powerful tool applied to the study of Leptonic Physics. This tool is based on the construction of Weak Basis invariant relations associated to different properties of leptonic models. The rationale behind these constructions is the fact that fermion mass matrices related through weak basis transformations look different but ...
