Search for single production of vector-like quarks decaying into Wb in pp collisions at s $$ \sqrt{s} $$ = 13 TeV with the ATLAS detector

open access: yesJournal of High Energy Physics, 2019
A search for singly produced vector-like quarks Q, where Q can be either a T quark with charge +2/3 or a Y quark with charge −4/3, is performed in proton–proton collision data at a centre-of-mass energy of 13 TeV corresponding to an integrated luminosity

The top quark width constrains from the single top quark production channel. [PDF]

open access: yesEPJ Web of Conferences, 2019
Using model independent and gauge invariant method proposed in previous studies we provide estimations on the top quark width measurement from the single top quark production channel and discuss the results of combining measurements from single and pair ...

Plasma LEAP2 concentration is associated with energy intake and postprandial insulin increase depending on meal size but not weight status in men

open access: yesDiabetes, Obesity and Metabolism, EarlyView.
Abstract Aims While LEAP2 is increasingly recognized as an appetite‐regulating hormone, its role in meal regulation and the dynamics of postprandial LEAP2 concentrations remain poorly understood in humans. The aim of the study was to (1) assess postprandial LEAP2 concentrations following a recommended‐energy breakfast, exploring potential association ...

The dual quark models

open access: yes, 2012
We briefly recall the historical environment around our 1971 and 1975 constructions of current-algebraic internal symmetry on the open string. These constructions included the introduction of world sheet fermions, the independent discovery of affine Lie algebra in physics (level one of affine su(3)), the first examples of the affine-Sugawara and coset ...

Process and individuation (on speculative realism and becoming)

open access: yesThe Southern Journal of Philosophy, EarlyView.
Abstract Recent developments in the continental tradition have taken a realist turn that reveals an oscillation between, on the one hand, an ontology of virtuality that thinks of reality as process and continuum (albeit a continuum of differences or events) and, on the other hand, the resurgence of an ontology of objects and essences guided by the ...

Sub-leading twist transverse momentum dependent parton distributions in the light-front quark-diquark model

open access: yesNuclear Physics B, 2023
In this study, the T-even sub-leading twist transverse momentum dependent distributions (TMDs) of proton in the light-front quark-diquark model (LFQDM) have been investigated. We have derived the overlap form of the light-front wave functions (LFWFs) for

Setting sail for Paris 2024: Retrospective analysis of world‐class ILCA 7 Olympic sailors’ cardiorespiratory fitness (2015–2020)

open access: yesExperimental Physiology, EarlyView.
Abstract The aim of this retrospective analysis was to provide a more comprehensive understanding of the cardiorespiratory profile of world‐class ILCA‐7 sailors (n = 3, all males), through a longitudinal evaluation offering real‐world data on physiological profile and exercise intensity domains. The cardiopulmonary exercise testing (CPET) was performed

Nonperturbative partonic quasidistributions of the pion from chiral quark models

open access: yesPhysics Letters B, 2017
We evaluate nonperturbatively the quark quasidistribution amplitude and the valence quark quasidistribution function of the pion in the framework of chiral quark models, namely the Nambu–Jona-Lasinio model and the Spectral Quark Model.
