Precision Measurements of Top Quark Production with the ATLAS Detector

open access: yesEPJ Web of Conferences, 2017
The top quark is the heaviest known fundamental particle. It is the only quark that decays before it hadronises which gives us the unique opportunity to probe the properties of bare quarks and to test perturbative QCD.

Post‐Exercise R‐1,3‐Butanediol did not Improve Markers of Fatigue or Recovery During a Multi‐Stage Mountain Bike Race

open access: yesEuropean Journal of Sport Science, Volume 26, Issue 11, November 2026.
ABSTRACT Evidence suggests that exogenous ketosis (EK) induced by ketone monoester (KME) supports recovery and attenuates physiological stress during endurance exercise. However, the potential benefits of the ketone precursor R‐1,3‐butanediol (BDO) during real‐world multi‐stage cycling remain unknown.

Boosted Top Quarks, Top Pair Resonances, and Top Partner Searches at the LHC

open access: yesEPJ Web of Conferences, 2013
The increased center-of-mass energy of proton-proton collisions at the LHC allows for higher and higher mass scales to be probed in the search for new physics. These searches for new physics can often involve the reconstruction of top quark decays.

Performance of pyDock in 8th CAPRI: Energy‐Based Scoring Applied to Docking and AlphaFold Models

open access: yesProteins: Structure, Function, and Bioinformatics, Volume 94, Issue 11, Page 1827-1835, November 2026.
ABSTRACT The 8th CAPRI edition has shown a significant evolution in the field of protein–protein complex structure prediction. We have participated in all 11 targets proposed in this edition, involving domain‐domain, protein–protein, protein‐peptide, and protein‐DNA interactions, including homo‐ and hetero‐meric interfaces.

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 ...

Polynomial Preconditioning for Indefinite Matrices

open access: yesNumerical Linear Algebra with Applications, Volume 33, Issue 5, October 2026.
ABSTRACT Polynomial preconditioning is an important tool in solving large linear systems and eigenvalue problems. A polynomial from GMRES can be used to precondition restarted GMRES and restarted Arnoldi. Here we give methods for indefinite matrices that make polynomial preconditioning more generally applicable. The new techniques include balancing the

Top quark production near threshold and the top quark mass [PDF]

open access: yesPhysics Letters B, 1999
We consider top-anti-top production near threshold in $e^+ e^-$ collisions, resumming Coulomb-enhanced corrections at next-to-next-to-leading order (NNLO). We also sum potentially large logarithms of the small top quark velocity at the next-to-leading logarithmic level using the renormalization group.

Deep learning approaches to top FCNC couplings to photons at the LHC

open access: yesJournal of High Energy Physics
We investigate the sensitivity of the LHC to flavour-changing neutral current interactions involving the top quark and a photon using a model-independent effective field theory framework, focusing on two complementary processes: single top production via

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.

Different demographic drivers of recovery in two adjacent populations of a long‐lived bird of prey

open access: yesOikos, Volume 2026, Issue 10, October 2026.
Understanding the demographic mechanisms underlying population decline or recovery is critical for conservation and management, yet similar population trends may arise from very different underlying processes. Comparing populations of vulnerable species groups like long‐lived raptors in different environments can reveal how species respond to change ...
