Search for associated production of Higgs boson and top-quark pairs with CMS [PDF]

open access: yes, 2022
At the LHC, the decay signal of top quark pairs produced in association with a Higgs boson (ttH), when all final state bodies decay into jet pairs, is deeply concealed within a huge background of inclusive top quark pair production.

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 ...

Measurements of new physics in top quark decay at LHC

open access: yes, 2013
A summary of ATLAS and CMS results on searches for new physics in top quark decay is presented. Three analysis are reported: the ATLAS and CMS searches for flavor changing neutral currents (FCNC) in top-quark decays and the CMS search for baryon number

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.

Search for W′ bosons decaying to a top and a bottom quark at s=13TeV in the hadronic final state

open access: yesPhysics Letters B, 2021
A search is performed for W′ bosons decaying to a top and a bottom quark in the all-hadronic final state, in proton-proton collisions at a center-of-mass energy of 13TeV.

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.

Galectin‐3 plasma levels are associated with left atrial contractile function in long‐distance runners

open access: yesExperimental Physiology, EarlyView.
Abstract High‐intensity endurance exercise induces myocardial remodelling as an adaptive response to sustained volume overload, but excessive cumulative training might also favour deleterious cardiac remodelling, including atrial fibrosis. Whether acute marathon running engages circulating fibrosis‐related biomarkers and whether these biomarkers track ...

Things decaying into top quarks, that are similar to top quarks, or that are produced with top quarks

open access: yes, 2008
Searches for new physics in the top-quark sector using data from proton-antiproton collisions at the Fermilab Tevatron are discussed. The large data sets collected by the D0 and CDF experiments allow for precision measurements of the standard model (SM) top-quark production rates and top quark properties so that deviations from the SM expectations can ...

Arterial–venous differences of brain‐derived neurotrophic factor isoforms across the brain and muscle after exercise at different intensities

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Exercise‐induced increases in forearm venous plasma and serum brain‐derived neurotrophic factor (BDNF) are often assumed to be indicative of release from the brain. Sixteen healthy and physically fit adults (20–40 years old) were recruited to investigate whether exercise‐induced changes in forearm venous mature BDNF (mBDNF) and ...
