[Nuclear] [EXTERNAL] Abstract Review for International Conference on New Frontiers in Physics

[El Fassi, Lamiaa]

Dear NPWG members,

I am sharing the abstract Nicolas Zambra would like to submit to the International Conference on New Frontiers in Physics: https://urldefense.proofpoint.com/v2/url?u=https-3A__indico.cern.ch_event_1307446_overview&d=DwIGaQ&c=CJqEzB1piLOyyvZjb8YUQw&r=oFpNaB86z9R0_Cm6JnqHF7R2h2vWMtKYuwr2PTSEYoE&m=ez_6A7NUNQIaBhJsBJQiZukZi-SasqHRNl7cgC-yLZhMIVZOltTlGwcqgSu7p7jV&s=OYNPeTPu6mQF5dRCrtEtKMNtFuUFIAiwzz0fn3lFvac&e= . The submission deadline is this Friday, July 5th. Thus, it would be appreciated if you could review it and send comments by noon this Friday. Please reply to Nikolas with any feedback by CC'ing me.
Thank you. I'm sorry for the short notice; I just received the abstract. I will post it shortly on our NPWG wiki page.

Happy 4th of July to whom it concerns 🙂!

Lamiaa

Dear All,


I hope this message finds you well.


Attached, you will find the abstract for our presentation at the International Conference on New Frontiers in Physics. I look forward to your comments and suggestions.


A Systematic Approach to Studying Quark Energy Loss in Nuclear Matter Using π+

Our objective is to test published models of partonic energy loss, particularly those describing the energy loss mechanisms of quarks traversing nuclear matter, within the framework of DIS. Our methodological approach focuses on quantifying quark energy loss in cold matter by analyzing positive pions produced in various nuclear targets, including Deuterium, Carbon, Iron, and Lead. To achieve this, we define a kinematic variable that helps isolate positive pions produced outside the nucleus. Before normalization, we perform acceptance corrections to account for the detector's efficiency and ensure accurate comparison of the spectra. By normalizing the energy spectra of positive pions produced from these distinct targets, and based on the BDMPS theory, which posits that quark energy loss depends only on nuclear size, we assume that the energy distributions of the targets will exhibit similar behavior. For this normalization, we identify an energy shift between these distributions, corresponding to the quark energy loss. To ensure accuracy, we employ statistical techniques such as the Kolmogorov-Smirnov test. To validate our methods, we used a preliminary dataset collected using Jefferson Lab's CLAS detector.


Thank you in advance for your time and feedback.

Best regards,
