- Nov 172:30 PMDoctoral Dissertation Oral Defense of James McIntyreDifferential cross sections for forward-angle photoproduction of π⁰, η, and η′ pseudoscalar mesons were measured using data from the RadPhi experiment conducted in Hall B at Jefferson Lab. RadPhi utilized a tagged bremsstrahlung photon beam incident on a stationary ⁹Be target, with a detector system configured to trigger on a recoil proton in coincidence with multiple neutral showers in the calorimeter. Events were reconstructed through kinematic fitting, with background suppressed via sideband subtraction and Monte Carlo modeling of nucleon resonance contributions. Cross sections were extracted over the photon energy range 4.4 - 5.4 GeV and binned in momentum transfer |t|, providing measurements from one of the first high-statistics experiments of forward η and η??? production from a nuclear target at these energies. Acceptance corrections were applied using a detailed GEANT-based simulation of the detector geometry and response. The resulting cross sections are consistent with 2020 CLAS results when scaled by the number of protons in beryllium, and show broad agreement with other data and theoretical models. In parallel, a high-resolution photon tagger detector, the Tagger Microscope (TAGM), was designed, constructed, and commissioned for the GlueX experiment in Hall D at Jefferson Lab. The TAGM was developed to improve energy resolution near the coherent bremsstrahlung peak by detecting post-bremsstrahlung electrons across a one GeV range along the focal plane of the tagging spectrometer. The detector consists of a 5x102 array of 2x2 mm² square BCF-20 plastic scintillating fibers thermally fused to BCF-98 light guide fibers optically coupled to silicon photomultipliers. These fibers are mounted in a precision-machined framework enabling fine positional adjustments to maintain precise alignment with post-bremsstrahlung electron trajectories, while ensuring mechanical rigidity, thermal stability, optical isolation, minimal inactive area, and radiation shielding for electronics. The construction effort involved extensive testing of fiber quality, light transmission, thermal fusing, radiation hardness, and defect analysis using SEM and EDX techniques. Following its installation and commissioning, the TAGM became a critical component of the GlueX beamline, enabling high-precision tagging essential for studies of hybrid mesons and gluonic excitations.

- Nov 173:00 PMGroup Therapy - BarbershopBarbershop The "Barbershop Group" is a therapy group for men who have had past traumatic experiences and would like to learn new ways of coping and managing the effects of that trauma. The group recognizes the need for men to develop different skills that will effectively improve how we express our emotions and build relationships in a safe space. What better place to do that than the barbershop? The Barbershop model is derived from the "Men's Trauma Recovery and Empowerment Model"- (M-TREM.) The Barbershop Group uses a Psycho-educational and skills-oriented approach that is person-centered. Over the years The Barbershop has provided men with a safe, non-judgmental setting where they can speak freely and be themselves. Unfortunately, we will not be providing haircuts, but we will be providing open discussion where honest responses in group discussions are encouraged, and we will engage in several exercises that are used to introduce you to and try new coping skills. I look forward to seeing you all at "The Shop".To join this group therapy session, please call SHaW at 860-486-4700 (tel:860-486-4705). This session is held by Greg Davis, LPC (https://studenthealth.uconn.edu/person/greg-davis/) For many concerns that students face – like overwhelming stress, anxiety, difficult relationships, depression, academic difficulties, and more – group therapy is the best option for support and healing. Facilitated by Student Health and Wellness (SHaW) counselors, our therapy groups encourage peer support, promote emotional wellbeing, and increase a felt sense of connection. Participants often find that they feel less alone in their struggles, and walk away with newfound support and ideas for coping.
- Nov 173:00 PMGroup Therapy - Huskies on Track: Navigating ADHD at UConnHuskies on Track: Navigating ADHD at UConn This group provides a space to discuss the ways ADHD can show up in your life. We'll focus on understanding how ADHD functions in the brain, navigating common challenges people with ADHD face, and talking about the emotional experience of living in a world designed for neurotypical people. The goal of this group is to help create a sense of community and understanding for students with ADHD at UConn. Example topics that the group will cover include time management, task prioritizing, and emotional regulation. All individuals who feel the group would be beneficial to them are welcome, regardless of whether they have a formal ADHD diagnosis.To join this group therapy session, please call SHaW at 860-486-4700 (tel:860-486-4705).
