Approximate solutions of the Schrödinger equation with energy-dependent screened Coulomb potential in D – dimensions

open access: yesEclética Química, 2020
Within the framework of the conventional Nikiforov-Uvarov method and a new form of Greene-Aldrich approximation scheme, we solved the Schrödinger equation with the energy-dependent screened Coulomb potential.

Matrix-Assisted Processes in CH4-Doped Ar Ices Irradiated with an Electron Beam

open access: yesMethane, 2023
The relaxation processes induced by exposure of the Ar matrices doped with CH4 (0.1–10%) to an electron beam were studied with a focus on the dynamics of radiolysis products—H atoms, H2 molecules, CH radicals, and energy transfer processes.

New physics in b → se+e−: A model independent analysis

open access: yesNuclear Physics B, 2021
The lepton universality violating flavor ratios RK/RK⁎ indicate new physics either in b→sμ+μ− or in b→se+e− or in both. If the new physics is only b→se+e− transition, the corresponding new physics operators, in principle, can have any Lorentz structure ...

B PHYSICS AT LHCb [PDF]

open access: yesInternational Journal of Modern Physics A, 2008
LHCb is a dedicated detector for b physics at the LHC (Large Hadron Collider). In this paper we present a concise review of the detector design and performance together with the main physics goals and their relevance for a precise test of the Standard Model and search of New Physics beyond it.

Probing New Physics in b → d transitions

open access: yesJournal of High Energy Physics, 2020
Recent experimental data on several observables in semileptonic B-meson decays are found to be in tension with the corresponding Standard Model predictions. Most of these deviations are related to b → c and b → s flavour changing transitions.

Majorana’s approach to nonadiabatic transitions validates the adiabatic-impulse approximation

open access: yesScientific Reports, 2023
The approach by Ettore Majorana for non-adiabatic transitions between two quasi-crossing levels is revisited and significantly extended. We rederive the transition probability, known as the Landau–Zener–Stückelberg–Majorana formula, and introduce ...

B physics and Quarkonia in CMS

open access: yesEPJ Web of Conferences, 2017
The heavy-flavor sector offers the opportunity to perform indirect tests of beyond the Standard Model physics through precision measurements and of quantum chromodynamics (QCD) through particle production studies. A review of recent measurements on heavy

Prospects for B c + $$ {B}_c^{+} $$ → τ + ν τ at FCC-ee

open access: yesJournal of High Energy Physics, 2021
This paper presents the prospects for a precise measurement of the branching fraction of the leptonic B c + $$ {B}_c^{+} $$ → τ + ν τ decay at the Future Circular Collider (FCC-ee) running at the Z -pole.
