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.

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.

The Unbefriended Patient, Their Professional Guardians, and Clinical Liaison Psychiatry: The Challenging Ethics of Changing Goals of Care.

AbstractUnbefriended patients are those with decisional impairments who lack family or friends to serve as healthcare surrogates. When such patients cannot make decisions, the court typically appoints a professional guardian to make choices aligned with the patient's values and preferences. However, this case report illustrates ethical challenges that can arise when professional guardians disregard the patient's authentic wishes.

Transgender Latinas' Perspectives on HIV PrEP Uptake, Condom Use, and Medically Supervised Gender-Affirming Hormone Therapy: Insights From ChiCAS Qualitative Interviews.

There is a dearth of HIV prevention behavioral interventions for transgender Latinas, despite this population's HIV risk. ChiCAS (Chicas Creando Acceso a la Salud) is an intervention to increase PrEP, condom, and gender-affirming hormone therapy (GAHT) use among transgender Latinas. To inform future work, semistructured interviews were conducted postintervention with 28 ChiCAS participants.

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.
