Ghizlane<\/span> Ez-Zobayr, IAP Physics Seminar Series will occur on Tuesday 23 September, at 11:15 <\/b>at the UM6P campus (Ryad 8, 1st floor<\/strong>).<\/p>\n Abstract:<\/span><\/b><\/span><\/p>\n The study presents a new measurement of light-by-light scattering in Pb+Pb collisions at a center-of-mass energy per nucleon pair of \u221asNN = 5.36 TeV, using data collected in 2023. The analysis utilizes a data set with an integrated luminosity of 1.7 nb\u207b\u00b9, recorded by the ATLAS experiment at the Large Hadron Collider (LHC). Light-by-light scattering candidates are identified in events featuring the exclusive production of two photons, with the following selection criteria: diphoton invariant mass (m\u03b3\u03b3) greater than 4 GeV, diphoton transverse momentum (pt\u03b3\u03b3) exceeding 2 GeV, diphoton acoplanarity (Aco) less than 0.01, and photon absolute pseudorapidity |\u03b7| within 2.37. Our contribution focuses on measuring the fiducial cross-section and four differential distributions, employing both bin-by-bin unfolding and iterative Bayesian unfolding techniques for the analysis<\/p>\n Biography<\/span><\/b><\/span>:<\/span> Ghizlane<\/span>\u00a0EZ-ZOBAYR\u00a0:<\/span><\/b>\u00a0<\/span>Ghizlane<\/span>\u00a0Ez-Zobayr, currently pursuing a PhD in high energy physics at the Institute of Applied Physics, Mohammed VI Polytechnic University, in collaboration with CERN- ATLAS experiment and under the supervision of Professor Yahya Tayalati and Professor Abdelouahed Elfatimy. I earned my bachelor’s degree in physics from Mohammed I University in 2021 and completed a master’s degree in physics of matter and radiation at Mohammed I University in 2023. For my master’s graduation project, I completed an internship at the Institute of Applied Physics, where I worked on the measurement of the W boson mass with the ATLAS detector, graduating as the valedictorian of my class.<\/p>\n
