Exogenous carbonaceous material on Phobos

J. Beccarelli, M. Pajola, M. Delbo, G. Munaretto et autres

We analyze Mars Express (MeX)/OMEGA Phobos' data in the 2.5–3.9 range to investigate the presence of organic material. We applied a thermal correction to the OMEGA data and identified regions of interest (ROIs) to extract mean spectra from the blue, red, and …

Measurement of distributions sensitive to the underlying event in inclusive Z boson production in pp collisions at s = 13 TeV with the ATLAS detector

G. Aad, B. Abbott, D. C. Abbott, O. Abdinov et autres

Abstract: This paper presents measurements of charged-particle distributions sensitive to the properties of the underlying event in events containing a Z boson decaying into a muon pair. The data were obtained using the ATLAS detector at the LHC in proton–proton collisions at …

Evidence for light-by-light scattering in heavy-ion collisions with the ATLAS detector at the LHC

P. Jackson, L. Lee, A. Petridis, M. J. White et autres

Light-by-light scattering (γγ → γγ) is a quantum-mechanical process that is forbidden in the classical theory of electrodynamics. This reaction is accessible at the Large Hadron Collider thanks to the large electromagnetic field strengths generated by ultra-relativistic colliding lead ions. Using 480 …

Measurement of inclusive jet charged-particle fragmentation functions in Pb+Pb collisions at sNN=2.76 TeV with the ATLAS detector

G. Aad, B. Abbott, J. Abdallah, S Abdel Khalek et autres

Measurements of charged-particle fragmentation functions of jets produced in ultra-relativistic nuclear collisions can provide insight into the modification of parton showers in the hot, dense medium created in the collisions.ATLAS has measured jets in √ s NN = 2.76 TeV Pb+Pb collisions …
