SUMMARY:Speaker: Nicola Neri (INFN) - Title: Probing Charm Baryon Dipole Moments at the LHC with ALADDIN
DESCRIPTION:Research Progress Meeting \nDate: August 14\, 2025 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Nicola Neri (INFN) \nTitle: Probing Charm Baryon Dipole Moments at the LHC with ALADDIN \nAbstract: The magnetic and electric dipole moments (MDM and EDM) of charm baryons have yet to be measured. These fundamental properties are sensitive probes of non-perturbative QCD dynamics and potential signatures of physics beyond the Standard Model. The proposed ALADDIN experiment at the LHC aims to perform the first direct measurement of charm baryon dipole moments by exploiting spin precession in bent crystals\, within a dedicated fixed-target setup. \nIn this novel scheme\, protons from the LHC beam halo are steered by a bent crystal (“crystal kicker”) onto a tungsten target\, producing charm baryons with energies up to the TeV scale. These baryons are then captured and channeled by a second bent crystal\, where their spins undergo precession under strong electromagnetic fields — allowing the extraction of their dipole moments. \nA recent proof-of-principle test\, TWOCRYST\, has successfully demonstrated the viability of this two-crystal configuration in the LHC environment. These results are a key step in validating the experimental concept and guiding the optimization of the ALADDIN setup. \nIn this talk\, I will present the physics case for ALADDIN\, detail the experimental technique and detector concept\, and provide an update on ongoing detector R&D efforts. I will also report on recent results from the TWOCRYST test\, which mark a significant milestone toward realizing this ambitious measurement program. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Darcy Newmark (MIT) - Title: Scintillation and Cherenkov Light Separation in a Liquid Argon Detector
DESCRIPTION:Research Progress Meeting \nDate: August 21\, 2025 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Darcy Newmark (MIT) \nTitle: Scintillation and Cherenkov Light Separation in a Liquid Argon Detector \nAbstract: This talk will present the first event-by-event observation of Cherenkov radiation from sub-MeV electrons in a high-yield scintillator (liquid argon) detector\, representing a milestone in low-energy particle detector development and one of the major goals of 2021 Snowmass Process. This work utilizes the Coherent CAPTAIN-Mills (CCM) experiment\, a 10-ton liquid argon light collection detector located at the Los Alamos National Lab pion decays at rest source. The detector is instrumented with 200 8-inch PMTs\, 80% of which are coated in a wavelength shifter and 20% are uncoated. Using gamma-rays from a sodium-22 radioactive source\, we have isolated prompt Chernekov light with >5 sigma confidence\, possible through the unique combination of coated and uncoated PMTs. Cherenkov light identification allows for a highly pure selection of electromagnetic events\, enabling exciting beyond Standard Model physics searches that I will review. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Ben Allanach (Cambridge) - Title: Z' bosons in light of B-anomalies
DESCRIPTION:Research Progress Meeting \nDate: August 28\, 2025 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Ben Allanach (Cambridge) \nTitle: Z’ bosons in light of B-anomalies \nAbstract: Many measurements of b->s transitions (when accompanied by a di-muon pair) disagree with state-of-the-art Standard Model (SM) predictions. On the other hand\, many other measurements\, including those measuring lepton flavour universality\, are in rough agreement with the SM.\nWe shall review such measurements and give a broad overview of the SM predictions. Z’ bosons with family-dependent couplings can significantly improve global fits. We give an example of a successful model\, re-cast LHC searches for it and provide HL-LHC sensitivity estimates. \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\n\nPasscode: 142239
