This study presents the first measurement of the f1(1285) resonance using the ALICE detector in inelastic proton–proton collisions at a center-of-mass energy of 13 TeV. The resonance is reconstructed at midrapidity (|y|< 0.5) through the hadronic decay channel f1(1285)→KS0K±π∓. Key measurements include the determination of its mass, transverse-momentum integrated yield, and average transverse mome

A measurement of the ratio of the branching fractions, Rτ/e = B(W → τν)/B(W → eν), is performed using a sample of W bosons originating from top-quark decays to final states containing τ-leptons or electrons. This measurement uses pp collisions at s = 13 TeV, collected by the ATLAS experiment at the Large Hadron Collider during Run 2, corresponding to an integrated luminosity of 140 fb−1. The W → τ

The human blood proteome provides a holistic readout of health states through the assessment of thousands of circulating proteins. In this study, we present a pan-disease resource to enable the study of diverse disease phenotypes within a harmonized proteomics dataset. by profiling protein concentrations across 59 diseases and healthy cohorts, we identified proteins associated with age, sex, and b

The first measurement of prompt D*+-meson spin alignment in ultrarelativistic heavy-ion collisions with respect to the direction orthogonal to the reaction plane is presented. The spin alignment is quantified by measuring the element ρ00 of the diagonal spin-density matrix for prompt D*+ mesons with 4 < pT< 30 GeV/c in two rapidity intervals, |y| < 0.3 and 0.3 < |y| < 0.8, in central (0–10%) and m

This paper contributes to the literature on urban climate change experiments by analysing ascribed advantages and challenges of organizing climate change experiments at the urban scale, and by examining how local actions translate into effect. We here distinguish between effects of experiments in achieving actual sustainability gains (‘goal-oriented objectives’) and instigating broader institution

Central to the sustainable production and consumption (SCP) agenda is the need for radical changes not only in the ways we produce but also in the ways we consume. The SCP agenda emerged within the understanding that it is not possible to reach the necessary reductions in environmental impact and resource consumption purely by technical solutions directed at improving the efficiency of production

Quantum information and quantum computing are based on the concept and manipulation of qubits. In this pedagogical Tutorial-written with the aim of assisting self-motivated undergraduate mathematics, physics, and engineering students-transformation of these qubits, especially the Hadamard transformation (H) and the phase shifter transformation (φ), is illustrated. Two-qubit gates and their applica

This Letter presents the first measurement of event-by-event fluctuations of the net number (difference between the particle and antiparticle multiplicities) of multistrange hadrons Ξ- and Ξ¯+ and its correlation with the net-kaon number using the data collected by the ALICE Collaboration in pp, p-Pb, and Pb-Pb collisions at a center-of-mass energy per nucleon pair sNN=5.02 TeV. The statistical ha

Sedan andra världskrigets slut har relationen mellan USA och Europa varit central för den internationella ordningen. Under senare år har relationen dock präglats av ökade säkerhetspolitiska spänningar och förändrade utrikespolitiska prioriteringar mellan amerikanska administrationer. Syftet med denna uppsats är att analysera hur Europa framställs i USA:s nationella säkerhetsstrategier från 2022 oc
