Mass Spectra and Decay Constants of Heavy‐Light Mesons: A Case Study of QCD Sum Rules and Quark Model

Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018
We visited mass spectra and decay constants of pseudoscalar and vector heavy‐light mesons (B, Bs, D, and DS) in the framework of QCD sum rule and quark model. The harmonic oscillator wave function was used in quark model while a simple interpolating current was used in QCD sum rule calculation.

Dark Matter phenomenology in 2HDMS

, 2023
The constituents of dark matter are still an unresolved puzzle. Several Beyond Standard Model (BSM) Physics offer suitable candidates. In this study here we consider the Two Higgs Doublet model augmented with a complex scalar singlet (2HDMS) and focus on

Electroweak spin-1 resonances in Composite Higgs models

Journal of High Energy Physics
Composite Higgs models predict the existence of various bound states. Among these are spin-1 resonances. We investigate models containing SU(2) L × SU(2) R as part of the unbroken subgroup in the new strong sector. These models predict that there are two

dE/dx from boosted long-lived particles

Journal of High Energy Physics, 2022
At colliders massive long-lived charged particles could be revealed through their anomalously large ionisation energy loss dE/dx. In this paper we explore a class of scenarios in which the LLPs are particularly boosted, owing to production from the decay

Neutrino Magnetic Moment in the Doublet‐Singlet Leptoquark Model

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.
The transition magnetic moment for Majorana neutrinos is studied in a simple extension of the Standard Model. This extension incorporates two scalar Leptoquarks S1 and R~2 with quantum numbers 3¯,113,/ and (3, 2, 1/6), respectively. It is found that these Leptoquarks generate a sizable transition magnetic moment, particularly when the quark bottom is ...

Exclusion Limits on a Scalar Decaying to Photons and Distinguishing Its Production Mechanisms

Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018
LHC run‐II has a great potential to search for new resonances in the diphoton channel. Latest 13 TeV data already put stringent limits on the cross sections in the diphoton channel assuming the resonance is produced through the gluon‐gluon fusion. Many beyond the Standard Model (SM) theories predict TeV‐scale scalars, which copiously decay to diphotons.

Combination and reinterpretation of LHC SUSY searches

Journal of High Energy Physics
To maximise the information obtained from various independent new physics searches conducted at the LHC, it is imperative to consider the combination of multiple analyses.

The role of vector boson fusion in the production of heavy vector triplets at the LHC and HL-LHC

Journal of High Energy Physics, 2022
We clarify the role of vector boson fusion (VBF) in the production of heavy vector triplets at the LHC and the HL-LHC. We point out that the presence of VBF production leads to an unavoidable rate of Drell-Yan (DY) production and highlight the subtle ...

The Spectrum of Neurologic Phenotypes Associated With NUS1 Pathogenic Variants: A Comprehensive Case Series

Annals of Neurology, Volume 98, Issue 3, Page 561-572, September 2025.
Objective A growing body of evidence indicates a strong genetic overlap between developmental and epileptic encephalopathies (DEEs) and movement disorders. De novo loss‐of‐function variants in NUS1 have been recently identified in DEE cases. Herein, we report a large cohort of cases with pathogenic NUS1 variants and describe their clinical presentation

LHC Probes of TeV‐Scale Scalars in SO(10) Grand Unification

Advances in High Energy Physics, Volume 2017, Issue 1, 2017., 2017
We investigate the possibility of TeV‐scale scalars as low energy remnants arising in the nonsupersymmetric SO(10) grand unification framework where the field content is minimal. We consider a scenario where the SO(10) gauge symmetry is broken into the gauge symmetry of the Standard Model (SM) through multiple stages of symmetry breaking, and a colored
