DESCRIPTION:This seminar will consist of three student speakers who have c
 ompleted HEP research projects over the summer.\n\nSpeaker: *Jonas Dej*\n\
 nTitle: *proANUBIS Data Analysis*\n\nAbstract: _ANUBIS is a proposed exper
 iment to discover Long-Lived Particles by placing Resistive Plate Chambers
  on the ceiling of the ATLAS cavern. Given its high sensitivity and low co
 st\, it is one of the most promising projects of its kind. In my talk\, I 
 will present the progress in its data analysis techniques\, including part
 icle track reconstruction\, alignment with the ATLAS detector\, and signal
  corrections._\n\nSpeaker: *Jesse (Yingchang) Zhang*\n\nTitle: *Developmen
 t of Efficiency Testing System and the Study of Eco-friendly Gas in RPC*\n
 \nAbstract: _The ANUBIS detector aims to search for dark matter through th
 e signatures of long-lived particles\, utilizing a series of tracking dete
 ctors\, including Resistive Plate Chambers (RPCs). This project focuses on
  developing and enhancing the system for evaluating RPC efficiency and tes
 ting performance of potential eco-friendly gas candidates._\n\n_The experi
 ment utilized two methods—scintillator-triggered and RPC self-triggered 
 modes—to measure the efficiency of RPCs with various gas mixtures\, incl
 uding the standard CERN mixture (as a reference)\, isobutane\, krypton\, a
 nd argon mixed with CO₂. Results indicated that while argon alone was an
  ineffective RPC gas\, adding approximately 3% argon to an 80% isobutane +
  20% CO₂ mixture significantly improved efficiency in self-triggered mod
 e. Additionally\, the study investigated the impact of high-voltage traini
 ng on enhancing RPC performance._\n\nSpeaker: *Shikang Ni*\n\nTitle: *Expe
 riment to Measure Muon Lifetime using 5x5 Array of Scintillator Bars*\n\nA
 bstract: _Cosmic rays offer a convenient and free source of energetic part
 icles for high energy physics experiments. Muons\, being the most abundant
  charged particles arriving at sea levels\, are a good target to perform m
 easurements on. By capturing muons in a scintillator bar and measuring its
  decay time\, we can work out its average lifetime. To build an experiment
  with multiple interacting components\, it is essential to understand the 
 experimental setup and check that individual components are working proper
 ly. In my talk\, I will go over a brief theoretical understanding of the e
 xperiment and the evolution of the experimental setup._
