Simultaneous Unbinned Differential Cross-Section Measurement of Twenty-Four Z+jets Kinematic Observables with the ATLAS Detector.

Z boson events at the Large Hadron Collider can be selected with high purity and are sensitive to a diverse range of QCD phenomena. As a result, these events are often used to probe the nature of the strong force, improve Monte Carlo event generators, and search for deviations from standard model predictions. All previous measurements of Z boson production characterize the event properties using a small number of observables and present the results as differential cross sections in predetermined bins.

Associations between Driving Cessation and Mental Health among Rural and Urban Older Adults.

Driving cessation is robustly associated with poor mental health outcomes among older adults; however, the magnitude of this relationship may differ by rurality. This study examined cross-sectional and longitudinal associations between driving cessation and life satisfaction and depressive symptoms and assessed whether these relationships were moderated by rurality. Data is from participants in the 2014 and 2016 Health and Retirement Study (HRS) (mean age = 73; 58% female) with information on either depressive symptoms (n=5,650) or life satisfaction (n=1,931).

Disentangling Sources of Momentum Fluctuations in Xe+Xe and Pb+Pb Collisions with the ATLAS Detector.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Posterior retroperitoneal adrenalectomy for metastatic disease: a multi-site Australian series.

Background: Posterior retroperitoneoscopic adrenalectomy (PRA) for isolated adrenal metastasis is minimally invasive, may prolong survival and improve quality of life. The current evidence base is scant.

Methods: A multi-site retrospective analysis of all cases of PRA for adrenal metastasis between 2011 and 2023, by four high-volume adrenal surgeons was performed.

Search for the Exclusive W Boson Hadronic Decays W^{±}→π^{±}γ, W^{±}→K^{±}γ and W^{±}→ρ^{±}γ with the ATLAS Detector.

A search for the exclusive hadronic decays W^{±}→π^{±}γ, W^{±}→K^{±}γ, and W^{±}→ρ^{±}γ is performed using up to 140  fb^{-1} of proton-proton collisions recorded with the ATLAS detector at a center-of-mass energy of sqrt[s]=13  TeV. If observed, these rare processes would provide a unique test bench for the quantum chromodynamics factorization formalism used to calculate cross sections at colliders. Additionally, at future colliders, these decays could offer a new way to measure the W boson mass through fully reconstructed decay products.
