Search for a new scalar resonance in flavour-changing neutral-current top-quark decays t → qX (q = u, c), with X → b b ¯ $$ b\overline{b} $$ , in proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2023
A search for flavour-changing neutral-current decays of a top quark into an up-type quark (either up or charm) and a light scalar particle X decaying into a bottom anti-bottom quark pair is presented. The search focuses on top-quark pair production where

Fixed-Angle Elastic Hadron Scattering [PDF]

open access: yes, 1999
The scattering amplitude in the dual model with Mandelstam analyticity and trajectory $\alpha (s)=\alpha_{0}-\gamma \ln [ (1+\beta \sqrt{s_{0} -s})/(1+ \beta \sqrt{s_{0}})]$ is studied in the limit $s,|t|\to \infty, s/t=const.$ By using the saddle point ...

Measurement of Higgs boson decay into b-quarks in associated production with a top-quark pair in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2022
The associated production of a Higgs boson and a top-quark pair is measured in events characterised by the presence of one or two electrons or muons. The Higgs boson decay into a b-quark pair is used.

Quantum GraviElectro Dynamics

open access: yesAnnalen der Physik, EarlyView.
The BRST invariant Lagrangian of the gravitationally interacting U(1)$U(1)$ gauge theory, namely the Quantum GraviElectro Dynamics (QGED). The Yan–Mills theory with the Hilbert–Einstein gravitational Lagrangian, namely the Yang–Mills–Utiyama (YMU) theory, is defined and quantised using the standard procedure. The theory is perturbatively renormalisable,

k_T factorization is violated in production of high-transverse-momentum particles in hadron-hadron collisions

open access: yes, 2007
We show that hard-scattering factorization is violated in the production of high-p_T hadrons in hadron-hadron collisions, in the case that the hadrons are back-to-back, so that k_T factorization is to be used.

In‐House Production of POFs Using Electrospinning, Melt‐Electrospinning and Melt‐Spinning for Cell‐Level Resolution Radiation Detectors

open access: yesJournal of Applied Polymer Science, Volume 142, Issue 48, December 20, 2025.
Optical transmission along a melt‐spun polystyrene microfiber with a diemeter of 80 um. ABSTRACT Since their discovery in 1965, scintillating plastic optical fibers have been used as radiation detectors in nuclear and high‐energy physics research.

Coulomb-hadron phase factor and spin phenomena in a wide region of transfer momenta [PDF]

open access: yes, 2000
The Coulomb-hadron interference effects are examined at small and large $t$. The methods for the definition of spin-dependent parts of hadron scattering amplitude are presented.

Search for new phenomena with top-quark pairs and large missing transverse momentum using 140 fb −1 of pp collision data at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics
A search is conducted for new phenomena in events with a top quark pair and large missing transverse momentum, where the top quark pair is reconstructed in final states with one isolated electron or muon and multiple jets.

Nuclear Physics in the Era of Quantum Computing and Quantum Machine Learning

open access: yesAdvanced Quantum Technologies, Volume 8, Issue 12, December 2025.
The use of QML in the realm of nuclear physics at low energy is almost nonexistent. Three examples of the use of quantum computing and quantum machine in nuclear physics are presented: the determination of the phase/shape in nuclear models, the calculation of the ground state energy, and the identification of particles in nuclear physics experiments ...
