DESCRIPTION:This seminar will consist of three student speakers who have c
 ompleted HEP research projects over the summer.\n\n\nSpeaker: *Cecilia Bom
 bari*\n\nTitle: *Muon Lifetime Experiment*\n\nAbstract: _The project focus
 es on the muon hodoscope\, a device designed to detect cosmic muons using 
 scintillation detectors. The system employs Silicon Photomultipliers (SiPM
 s) to convert the light from scintillators into electrical signals. A sign
 ificant part of the work involved automating the threshold scanning proces
 s\, which is crucial for optimizing the signal-to-noise ratio in muon dete
 ction. I developed new software that fully automates the threshold scan\, 
 significantly improving the efficiency and accuracy of the system. This au
 tomation ensures more precise detection by setting optimal thresholds to d
 ifferentiate true muon signals from noise. The experience highlighted the 
 importance of bit-by-bit data analysis in tracking scintillator firings ca
 used by the passage of muons\, contributing to advancements in the calibra
 tion and performance of the hodoscope._\n\nSpeaker: *Joseph Garvey*\n\nTit
 le: *Modernising lab teaching with Open-Source Software: Tracing Particle 
 Tracks.*\n\nAbstract: _The particle tracks experiments performed in Part I
 I involved labour intensive\, manual tracing of the original film slides t
 o measure the properties of subatomic particle decay. By developing open-s
 ource software tools to perform these measurements\, better data can be pr
 oduced and more time can be spent conveying the central ideas of the exper
 iment\, greatly improving student experience and teaching quality._\n\n_A 
 tool was developed based upon the open-source multi-dimensional image tool
  Napari\, and modified to perform and store measurements of particle track
 s across 3 different perspectives and many events. The resulting tool has 
 been open-sourced\, and will see its first use in Michaelmas '24 teaching.
 _\n\nSpeaker: *Ritwik Mangrulkar*\n\nTitle: *Prospects for searches of inv
 isible B(s) meson decays at FCC-ee.*\n\nAbstract: _The Future Circular Col
 lider (FCC) is a proposed particle collider at CERN intended for operation
  in the mid-second half of this century. As part of the ongoing FCC feasib
 ility study\, this talk discusses the potential of the electron-positron c
 onfiguration (FCC-ee) to investigate invisible decays of B(s) mesons at th
 e Z-pole. These disappearance decays are strongly helicity suppressed in t
 he Standard Model (SM) and thus serve as a powerful null test\, as well as
  probes for New Physics (NP) with experimentally viable sensitivities._
