Search for new phenomena in multi-body invariant masses in events with at least one isolated lepton and two jets using s $$ \sqrt{s} $$ = 13 TeV proton–proton collision data collected by the ATLAS detector

open access: yesJournal of High Energy Physics, 2023
A search for resonances in events with at least one isolated lepton (e or μ) and two jets is performed using 139 fb −1 of s $$ \sqrt{s} $$ = 13 TeV proton–proton collision data recorded by the ATLAS detector at the LHC. Deviations from a smoothly falling

Measurement of the inclusive production of neutral pions and charged particles on the Z0 resonance [PDF]

open access: yesPhysics Letters B, 1991
Abstract We present a study of the inclusive production of neutral pions and charged particles from 112 000 hadronic Z 0 decays. The measured inclusive momentum distributions can be reproduced by parton shower Monte Carlo programs and also by an analytical QCD calculation.

Hadronic resonances, strange and multi-strange particle production in Xe-Xe and Pb-Pb collisions with ALICE at the LHC [PDF]

open access: yesNuclear Physics A, 2019
We present measurements of hadronic resonance, strange and multi-strange particle production in collisions of Xe-Xe and Pb-Pb at the center-of-mass energies of root s(NN) = 5.44 and 5.02 TeV, respectively, by the ALICE collaboration at the LHC. Particle ratios are presented as a function of multiplicity for K-s(0), Lambda, Xi(-), (Xi) over bar ...

Simultaneous isotopic analysis of fission product Sr, Mo, and Ru in spent nuclear fuel particles by resonance ionization mass spectrometry

open access: yesScientific Reports, 2023
AbstractFission product Sr, Mo, and Ru isotopes in six 10-μm particles of spent fuel from a pressurized water reactor were analyzed by resonance ionization mass spectrometry (RIMS) and evaluated for utility in nuclear material characterization. Previous measurements on these same samples showed widely varying U, Pu, and Am isotopic compositions owing ...

The production of high-momentum particles and resonances in pp collisions at the CERN intersecting storage rings [PDF]

open access: yesNuclear Physics B, 1983
Data are reported on the momentum distributions of Λ, Λ (1520), φ (1020), Λ and p, inclusively produced between 1° and 2° with respect to one of the primary proton beams at the CERN Intersecting Storage Rings. In addition, the decay angular distribution of the Λ(1520), the ratio of the cross sections for the production of Σ− (1385) and Σ+ (1385) and ...

Measurement of e+e − → K+K − π 0 cross section and observation of a resonant structure

open access: yesJournal of High Energy Physics, 2022
Based on e + e − collision data collected by the BESIII detector at the BEPCII collider at center-of-mass energies from 2.000 to 3.080 GeV, a partial-wave analysis is performed for the process e + e − → K + K − π 0.

Lattice QCD Thermodynamics and RHIC-BES Particle Production within Generic Nonextensive Statistics [PDF]

open access: yesPhysics of Particles and Nuclei Letters, 2017
The current status of implementing Tsallis (nonextensive) statistics on high-energy physics is briefly reviewed. The remarkably low freezeout-temperature, which apparently fails to reproduce the firstprinciple lattice QCD thermodynamics and the measured ...
