Recent results on top quark mass and properties and rare/anomalous top quarks interactions in CMS

open access: yesSciPost Physics Proceedings, 2022
The amount of data collected by the CMS experiment at the CERN LHC in the second data taking period provides the possibility to study absolute and differential cross sections of top quark interaction processes with high precision.

Extracting the top-quark running mass using $t\bar{t}$+1-jet events produced at the Large Hadron Collider [PDF]

open access: yes, 2017
We present the calculation of the next-to-leading order QCD corrections for top-quark pair production in association with an additional jet at hadron colliders, using the modified minimal subtraction scheme to renormalize the top-quark mass.

Tumbling top-quark condensate model [PDF]

open access: yesPhysical Review D, 1992
We propose a renormalizable model with no fundamental scalars which breaks itself in the manner of a "tumbling" gauge theory down to the standard model with a top-quark condensate. Because of anomaly cancellation requirements, this model contains two color sextet fermions (quixes), which are vector-like with respect to the standard model gauge group ...

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

open access: yesExperimental Physiology, EarlyView.
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 ...

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 ...

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, EarlyView.
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${

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 ...

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.

Searches for New Physics in Top Decays at D0

open access: yes, 2011
The Tevatron proton-antiproton collider at Fermilab with its centre of mass energy of 1.96 TeV allows for pair production of top quarks and the study of top quark decay properties.
