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

Eight weeks of post‐exercise local heating does not improve cognition and plasma brain‐derived neurotrophic factor concentrations

open access: yesExperimental Physiology, EarlyView.
Abstract Exercise and heat stress have been reported to independently provide benefits to brain health. We tested the hypothesis that 8 weeks of post‐exercise local heating, passive local heating only, or exercise training only improves cognitive performance compared to a control group.

Large methane oxidation across an oxygen gradient in Baltic Sea deep waters

open access: yesLimnology and Oceanography Letters, Volume 11, Issue 1, January 2026.
Abstract Robust estimations of methane (CH4) oxidation in marginal seas remain elusive, making CH4 budgets particularly uncertain. Here, we investigate the CH4 benthic source and bottom layer oxidation across the entire Baltic Sea using concentration and stable isotope (δ13C‐CH4) profiles along oxygen and salinity gradients.

Top-Yukawa contributions to bbH production at the LHC

open access: yesJournal of High Energy Physics, 2019
We study the production of a Higgs boson in association with bottom quarks b b ¯ H $$ \left(b\overline{b}H\right) $$ in hadronic collisions at the LHC, including the different contributions stemming from terms proportional to the top-quark Yukawa ...

Prospects for observing an additional NMSSM Higgs boson produced in association with a single bottom quark at the LHC

open access: yesResults in Physics, 2021
We study the production of the next-to-lightest CP-even Higgs state, which is not the SM-like Higgs, of the NMSSM in association with a single bottom quark bg→bh2in the ditau decay channel at the LHC. We find that this production channel can be exploited

A Superalgebra Within: Representations of Lightest Standard Model Particles Form a Z25$\mathbb {Z}_2^5$‐Graded Algebra

open access: yesAnnalen der Physik, Volume 537, Issue 12, December 2025.
 A set of particle representations, familiar from the Standard Model, collectively form a superalgebra. Those representations mirroring the behaviour of the Standard Model's gauge bosons, and three generations of fermions, are each included in this algebra, with exception only to those representations involving the top quark.

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 ...

Beautiful and charming chromodipole moments

open access: yesJournal of High Energy Physics, 2021
In the context of the Standard Model effective field theory we derive direct and indirect bounds on chromodipole operators involving the bottom and charm quark.

Radiation Transport Through the Martian Atmosphere as a Function of the Zenith Angle

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 12, December 2025.
Abstract The topographic influence of the radiation environment on the Martian surface radiation is crucial for future human exploration. Topographic maps help assess radiation flux variations, aiding in hazard evaluation. Creating a global radiation map requires accounting for seasonally varying atmospheric density, heliospheric modulation, and ...

Search for electroweak production of a vector-like T quark using fully hadronic final states

open access: yesJournal of High Energy Physics, 2020
A search is performed for electroweak production of a vector-like top quark partner T of charge 2/3 in association with a top or bottom quark, using proton-proton collision data at s $$ \sqrt{s} $$ = 13 TeV collected by the CMS experiment at the LHC in ...
