Combined explanations of B-physics anomalies, $$(g-2)_{e, \mu }$$ ( g - 2 ) e , μ and neutrino masses by scalar leptoquarks

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
We extend the contents of the standard model (SM) by introducing TeV-scale scalar leptoquarks to generate neutrino masses and explain some current observed deviations from the SM predictions, including the anomalous magnetic moments of charged leptons ...

Chiral Phase Transition in Linear Sigma Model with Nonextensive Statistical Mechanics

open access: yesAdvances in High Energy Physics, 2017
From the nonextensive statistical mechanics, we investigate the chiral phase transition at finite temperature T and baryon chemical potential μB in the framework of the linear sigma model.

$${b\rightarrow c\tau \nu }$$ b→cτν transitions in the standard model effective field theory

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
The $$R(D^{(*)})$$ R(D(∗)) anomalies observed in $$B\rightarrow D^{(*)}\tau \nu $$ B→D(∗)τν decays have attracted much attention in recent years. In this paper, we study the $$B\rightarrow D^{(*)}\tau \nu $$ B→D(∗)τν , $$\Lambda _b\rightarrow \Lambda _c ...

Power-aligned 2HDM: a correlative perspective on (g − 2) e,μ

open access: yesJournal of High Energy Physics, 2021
With the hypothesis of minimal flavor violation, we find that there exists a power-aligned relation between the Yukawa couplings of the two scalar doublets in the two-Higgs-doublet model with Hermitian Yukawa matrices.

Leptonic Scalars versus Scalar Leptons [PDF]

open access: yesProceedings of Corfu Summer Institute 2019 "School and Workshops on Elementary Particle Physics and Gravity" — PoS(CORFU2019), 2020
The notion of scalars having lepton number, i.e. leptonic scalars, is discussed without supersymmetry, where scalar leptons reside. It is shown how dark parity comes from lepton parity, as well as its possible origin from grand unification. Two specific phenomenological applications to dark matter are described.

Superstructure Reconstruction Stabilizes Anionic Redox in Cobalt‐Free Lithium‐Rich Layered Cathodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Superstructure reconstruction through Ni3+‐induced Ni/Mn exchange stabilizes the anionic redox in cobalt‐free lithium‐rich cathodes. This strategy mitigates oxygen loss and transition metal migration, yielding high capacity (231 mAh g−1) and durable cycling (84% over 500 cycles) with suppressed voltage decay. Structural degradation in Li‐rich manganese‐

Neutrino masses and lepton flavour violating phenomena in the MSSM [PDF]

open access: yes, 2007
The most general supersymmetric model with minimal particle content and an additional discrete Ƶ(_3) symmetry, which allows lepton number violating terms, is considered. In this model, we calculate at the level of one-loop the resulting Majorana neutrino

Lepton PDFs and multipurpose single-lepton searches at the LHC

open access: yesPhysical Review D, 2023
A final state consisting of one charged lepton, at least one jet, and little missing transverse energy can be a very promising signature of new physics at the LHC across a wide range of models. However, it has received only limited attention so far. In this work we discuss the potential sensitivity of this channel to various new physics scenarios.

Falls and Nursing Workload in Hospitalized Older Adults With Delirium: A Controlled Trial of 3D‐Radar‐Based Bed‐Exit Monitoring Versus Contact Mat

open access: yesJournal of the American Geriatrics Society, EarlyView.
Using objectively verified fall data in hospitalized patients with delirium, a contactless three‐dimensional radar‐based bed‐exit monitoring system was associated with fewer bed‐exit‐related falls and lower bed‐exit‐related nursing workload than an analogue contact mat.
