Top quark physics with the CMS experiment

open access: yesEPJ Web of Conferences, 2014
An overview of recent top quark measurements in proton-proton collisions at √s = 7 and 8 TeV in data collected with the CMS experiment at the LHC, using a data sample collected during the years 2011 and 2012 is presented.

Cerebral oxygen extraction across different exercise intensities: Role of arterial PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_2}}}$

open access: yesExperimental Physiology, EarlyView.
Abstract Stability in cerebral oxygen extraction fraction (OEF) is typically determined by alterations in cerebral blood flow (CBF). At rest, arterial partial pressure of carbon dioxide (PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$) and OEF exhibit a strong inverse relationship owing to the powerful influence of PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_2}}}$

Top quark mass in top quark condensation model

open access: yesPhysics Letters B, 1992
Abstract The top quark mass mt in the top quark condensation model is calculated with the ladder Schwinger-Dyson equation including the gluon exchange. Instead of the Pagels-Stokar approximation, for fixing the value of the coupling constant the Goldstone boson decay constant is calculated with the solution of the covariant Bethe-Salpeter equation ...

Nonperturbative fragmentation of the top quark [PDF]

open access: yesPhysical Review D, 1991
By the use of a simple phenomenological string model, the energy lost by the top quark through nonperturbative fragmentation effects before its weak decay is computed. This energy lost is in first approximation proportional to the rate between the decay time and the hadronization time of the top as measured in the center-of-mass frame of the top and ...

Eight weeks of post‐exercise local heating does not improve cognition and plasma brain‐derived neurotrophic factor concentrations

open access: yesExperimental Physiology, EarlyView.
Abstract Exercise and heat stress have been reported to independently provide benefits to brain health. We tested the hypothesis that 8 weeks of post‐exercise local heating, passive local heating only, or exercise training only improves cognitive performance compared to a control group.

Off-Shell Effects for Single Top-Quark Production Processes at Hadron Colliders [PDF]

open access: yes, 2011
We present a calculation of s- and t-channel single top-quark production and decay at next-to-leading order in QCD for the Tevatron and for the LHC. The calculation includes the off-shell effects of the intermediate top-quark and the non-factorisable ...
