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.

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.

Fundamental physics with the Square Kilometre Array [PDF]

open access: yesPublications Astronomical Society of Australia, 2018
The Square Kilometre Array (SKA) is a planned large radio interferometer designed to operate over a wide range of frequencies, and with an order of magnitude greater sensitivity and survey speed than any current radio telescope. The SKA will address many

The CKM unitarity problem: a trace of new physics at the TeV scale? [PDF]

open access: yesThe European Physical Journal C, 2019
After the recent high precision determinations of $$V_{us}$$ V us and $$V_{ud}$$ V ud , the first row of the CKM matrix shows more than $$4\sigma $$ 4 σ deviation from unitarity.

New Physics in B decays

open access: yesEPJ Web of Conferences, 2016
While the LHC did not observe direct evidence for physics beyond the standard model, indirect hints for new physics were uncovered in the flavour sector in the decays B → K*µ+ µ−, B → Kµ+ µ−/B → Ke+e−, Bs → øµ+µ−, B → D(*) τv and h → τ±µ∓.

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 ...

The basic physics of the binary black hole merger GW150914 [PDF]

open access: yesAnnals of Physics, 2016
The first direct gravitational‐wave detection was made by the Advanced Laser Interferometer Gravitational Wave Observatory on September 14, 2015. The GW150914 signal was strong enough to be apparent, without using any waveform model, in the filtered ...

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.
