Model-independent sensitivity estimates for the electromagnetic dipole moments of the top quark at the Large Hadron Collider and beyond

open access: yesNuclear Physics B, 2020
As the heaviest known fundamental particle, the top quark ensures testing of the Standard Model and occupies a significant role in a lot of theories of new physics beyond the Standard Model.

Sex and performance‐level differences in aerobic and haematological parameters among elite ski mountaineering athletes

open access: yesExperimental Physiology, Volume 111, Issue 4, Page 1988-2001, 1 April 2026.
Abstract Ski mountaineering (SkiMo) is a new Olympic sport with extreme endurance demands and altitude exposure. Previous studies have focused on traditional cardiorespiratory variables, such as maximal oxygen consumption (V̇O2max${\dot V_{{{\mathrm{O}}_{\mathrm{2}}}{\mathrm{max}}}}$) or ventilatory thresholds, but, to our knowledge, did not report ...

Effect of hypoxia on muscle activation at equivalent absolute and relative intensity during incremental and constant load exercise to task failure

open access: yesExperimental Physiology, Volume 111, Issue 4, Page 1933-1947, 1 April 2026.
Abstract We examined the impact of moderate hypoxia (HYPO) on muscle activation during incremental exercise matched for both absolute and equivalent relative intensity. Fifteen active subjects (10 males, 5 females) completed two ramp incremental test and two step tests in normoxia (NORM; FiO2${F_{{\mathrm{i}}{{\mathrm{O}}_2}}}$ = 0.209) and HYPO (FiO2${

Females exhibit greater cardiac volume reductions with expiratory muscle loading during submaximal exercise compared to males

open access: yesThe Journal of Physiology, Volume 604, Issue 7, Page 3175-3200, 1 April 2026.
Abstract figure legend Intrathoracic pressure (ITP) manipulation during submaximal exercise reveals load‐ and sex‐specific cardiac volume responses. Inspiratory loading increased oesophageal pressure swings and the work of breathing (Wb) but did not alter stroke volume (SV) or ventricular volumes in males or females.

Quantum tops at circular lepton colliders

open access: yesJournal of High Energy Physics
We study the quantum properties of top quark pairs in lepton colliders with unpolarised beams, including spin correlations, entanglement, and violation of Bell inequalities.

Model-independent constraints on the CKM matrix elements |V tb |, |V ts | and |V td |

open access: yesJournal of High Energy Physics, 2019
Single top quark production cross sections at hadron colliders are traditionally used to extract the modulus of the V tb element of the Cabibbo-Kobayashi-Maskawa matrix under the following assumption: |V tb | ≫ |V td |, |V ts |.

Tevatron Top-Quark Combinations and World Top-Quark Mass Combination

open access: yes, 2014
Almost 20 years after its discovery, the top quark is still an interesting particle, undergoing precise investigation of its properties. For many years, the Tevatron proton antiproton collider at Fermilab was the only place to study top quarks in detail,

Alternative methods for top-quark mass determination at the Tevatron and LHC

open access: yes, 2013
I am summarizing here the determination of the top-quark mass from the CDF and D0 Collaborations at the Tevatron and the ATLAS and CMS Collaborations at the LHC using non-conventional methods.
