Boosted top quark polarization [PDF]

open access: yesPhysical Review D, 2019
In top quark production, the polarization of top quarks, decided by the chiral structure of couplings, is likely to be modified in the presence of any new physics contribution to the production. Hence the same is a good discriminator for those new physics models wherein the couplings have a chiral structure different than that in the Standard Model (SM)

Top quark property at Tevatron

open access: yesEPJ Web of Conferences, 2013
The top quark, the heaviest known elementary particle, remains by far the most interesting particle to test standard model as well as search new physics beyond standard model because of its large mass and unique properties. Having data collected about 10

Top quark mass studies with t t ¯ j $$ t\overline{t}j $$ at the LHC

open access: yesJournal of High Energy Physics, 2018
A precise measurement of the top quark mass, a fundamental parameter of the Standard Model, is among the most important goals of top quark studies at the Large Hadron Collider.

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

Measurement of the top quark mass with the ATLAS detector using tt¯ events with a high transverse momentum top quark

open access: yesPhysics Letters B
The mass of the top quark is measured using top-quark-top-antiquark pair events with high transverse momentum top quarks. The dataset, collected with the ATLAS detector in proton–proton collisions at s=13 TeV delivered by the Large Hadron Collider ...

Tevatron combined top quark mass

open access: yesEPJ Web of Conferences, 2013
We summarize the top-quark mass measurements from the CDF and D0 experiments at Fermilab. We combine published Run I (1992–1996) measurements with the most precise published and preliminary Run II (2001–2012) measurements using a data set corresponding ...

Exercise Intolerance in Young Physically Active Smokers Compared to Non‐Smokers During Sinusoidal Cycling

open access: yesEuropean Journal of Sport Science, Volume 26, Issue 9, September 2026.
ABSTRACT The impact of cigarette smoking on the cardiorespiratory response to exhaustive exercise remains unclear. This study investigated the smoking effect on exercise tolerance by analyzing the cardiorespiratory and metabolic variables during an exhausting sinusoidal exercise in young physically active smokers (SM) without known cardiovascular and ...

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.
