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 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.

A better understanding of the lived experience of those with YOPD is essential to delivering bespoke rehabilitation and improving quality of life.
Purpose: To provide insight into the emotional and social lived experience of individuals with YOPD.
Importance: Chronic traumatic encephalopathy (CTE) is a neurodegenerative tauopathy associated with repetitive head impacts (RHIs). Prior research suggests a dose-response association between American football play duration and CTE risk and severity, but this association has not been studied for ice hockey.
Objective: To investigate associations of duration of ice hockey play with CTE diagnosis and severity, functional status, and dementia.
Article Synopsis
- Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease linked to frequent head injuries, often seen in athletes and military personnel, with a focus on its relationship with aggression and family mental health history.
- The study analyzed data from deceased male brain donors with CTE, aiming to determine if the presence of CTE affects the relationship between first-degree family history of mental illness (1°FHMI) and aggression, using structured assessments and various demographic controls.
- Results indicated that 1°FHMI was significantly correlated with aggression scores in individuals with CTE, suggesting that CTE pathology may influence aggression differently than previously understood, while no such association was found in those without CTE.
