RD*,RK* $$ {R}_{D^{\left(*\right)}},{R}_{K^{\left(*\right)}} $$ and neutrino mass in the 2HDM-III with right-handed neutrinos

Journal of High Energy Physics, 2018
Given that the two-Higgs-doublet model of type III (2HDM-III) has the potential to address the RD* $$ {R}_{D^{\left(*\right)}} $$ anomalies while the resolution to the RK* $$ {R}_{K^{\left(*\right)}} $$ deficits requires new degrees of freedom within ...

New physics in the angular distribution of B c − $$ {B}_c^{-} $$ → J/ψ(→ μ + μ − )τ − (→ π − ν τ ) ν ¯ τ $$ {\overline{\nu}}_{\tau } $$ decay

Journal of High Energy Physics, 2021
In B c − $$ {B}_c^{-} $$ → J/ψ(→ μ + μ − )τ − ν ¯ τ $$ {\overline{\nu}}_{\tau } $$ decay, the three-momentum p τ − $$ {\boldsymbol{p}}_{\tau^{-}} $$ cannot be determined accurately due to the decay products of τ − inevitably include an undetected ν τ ...

Modular invariant models of lepton masses at levels 4 and 5 [PDF]

Journal of High Energy Physics, 2019
We explore alternative descriptions of the charged lepton sector in modular invariant models of lepton masses and mixing angles. In addition to the modulus, the symmetry breaking sector of our models includes ordinary flavons.

Analysis of carbohydrates and glycoconjugates by matrix‐assisted laser desorption/ionization mass spectrometry: An update for 2021–2022

Mass Spectrometry Reviews, Volume 44, Issue 3, Page 213-453, May/June 2025.
Abstract The use of matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this review is the 12th update of the original article published in 1999 and brings coverage of the literature to the end of 2022.

Phenomenological anatomy of top-quark FCNCs induced by a light scalar singlet

Journal of High Energy Physics
Scalar singlets under the Standard Model gauge group appear naturally in many well-motivated New Physics scenarios, such as the composite Higgs models. Unlike the Higgs boson in the Standard Model, they can induce large flavour-changing neutral currents (

B s(d) − B ¯ $$ \overline{B} $$ s(d) mixing and B s → μ + μ − decay in the NMSSM with the Flavour Expansion Theorem

Journal of High Energy Physics, 2019
In this paper, motivated by the observation that the Standard Model predictions are now above the experimental data for the mass difference ΔM s(d), we perform a detailed study of B s(d) − B ¯ $$ \overline{B} $$ s(d) mixing and B s → μ + μ − decay in the

Neutrinoloser Doppelbetazerfall: Der Gral der Neutrinophysik

Physik in unserer Zeit, Volume 56, Issue 3, Page 132-137, May 2025.
Die Entschlüsselung der Neutrinoeigenschaften ist auch siebzig Jahre nach ihrer Entdeckung noch nicht abgeschlossen. Es wäre eine spektakuläre Entdeckung, sollten Neutrinos ihre eigenen Antiteilchen sein und sich folglich als Majorana‐Teilchen entpuppen. Mehrere Experimente untersuchen diese Möglichkeit.

Deciphering the Belle II data on B → Kν ν ¯ $$ B\to K\nu \overline{\nu} $$ decay in the (dark) SMEFT with minimal flavour violation

Journal of High Energy Physics
Recently, the Belle II collaboration announced the first measurement of the branching ratio B B + → K + ν ν ¯ $$ \mathcal{B}\left({B}^{+}\to {K}^{+}\nu \overline{\nu}\right) $$ , which is found to be about 2.7σ higher than the Standard Model (SM ...

Potential analysis of holographic Schwinger effect in the magnetized background

European Physical Journal C: Particles and Fields, 2020
We study the holographic Schwinger effect with magnetic field at RHIC and LHC energies by using the AdS/CFT correspondence. We consider both weak and strong magnetic field cases with $$B\ll T^2$$ B≪T2 and $$B\gg T^2$$ B≫T2 solutions respectively. Firstly,

A Note on the Connection between Non-Additive Entropy and h-Derivative

Entropy, 2023
In order to study as a whole a wide part of entropy measures, we introduce a two-parameter non-extensive entropic form with respect to the h-derivative, which generalizes the conventional Newton–Leibniz calculus.
