Measurement of the W boson polarisation in $$t\bar{t}$$ tt¯ events from pp collisions at $$\sqrt{s}$$ s = 8 TeV in the lepton + jets channel with ATLAS

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
This paper presents a measurement of the polarisation of W bosons from $$t\bar{t}$$ tt¯ decays, reconstructed in events with one high-$$p_{\text{ T }}$$ pT lepton and at least four jets. Data from pp collisions at the LHC were collected at $$\sqrt{s}$$ s

Host species and age‐specific variation on Hepatozoon prevalence and its effect on body condition in two Neotropical crocodiles

open access: yesWildlife Biology, Volume 2025, Issue 5, September 2025.
Many populations of species belonging to the order Crocodilia are threatened due to illegal trafficking, indiscriminate hunting, and habitat loss and degradation affecting crocodilian health and parasitic load. Although several studies have revealed that crocodiles, caimans, and alligators are frequently infected by Hepatozoon spp., the results from ...

Constraining off-shell Higgs boson production and the Higgs boson total width using WW → ℓνℓν final states with the ATLAS detector

open access: yesPhysics Letters B
A measurement of off-shell Higgs boson production is performed in the H* → WW channel. The measurement uses a proton–proton collision dataset with an integrated luminosity of 140 fb−1 collected at a centre-of-mass energy of 13 TeV by the ATLAS detector ...

Measurement of the cross-section for producing a W boson in association with a single top quark in pp collisions at s=13 $$ \sqrt{s}=13 $$ TeV with ATLAS

open access: yesJournal of High Energy Physics, 2018
The inclusive cross-section for the associated production of a W boson and top quark is measured using data from proton-proton collisions at s=13 $$ \sqrt{s}=13 $$ TeV. The dataset corresponds to an integrated luminosity of 3.2 fb−1, and was collected in

Ligand bias and inverse agonism on 5‐HT2A receptor‐mediated modulation of G protein activity in post‐mortem human brain

open access: yesBritish Journal of Pharmacology, Volume 182, Issue 14, Page 3320-3335, July 2025.
Abstract Background and Purpose Whereas biased agonism on the 5‐HT2A receptor has been ascribed to hallucinogenic properties of psychedelics, no information about biased inverse agonism on this receptor is available. In schizophrenia, increased 5‐HT2A receptor constitutive activity has been suggested, highlighting the therapeutic relevance of inverse ...

Visualizing mitochondrial FoF1-ATP synthase as the target of the immunomodulatory drug Bz-423

open access: yes, 2018
Targeting the mitochondrial enzyme FoF1-ATP synthase and modulating its catalytic activities with small molecules is a promising new approach for treatment of autoimmune diseases. The immuno-modulatory compound Bz-423 is such a drug that binds to subunit

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 ...
