G03.00001: Developing detectors for the future Electron-Ion Collider Invited Speaker: Greg Kalicy The next generation facility for QCDin the United States will be the Electron-Ion Collider (EIC), planned to be built in the Brookhaven National Laboratory (BNL). The EIC will be a powerful new high-luminosity facility with the capability to collide high-energy electron beamswith high-energy proton and ion beams, providing access to those regions in the nucleon and nuclei where their structure is dominated by gluons. After definingguidancefor ageneral-purpose detector conceptand the underlying technologies to meet the physics requirementsin EIC Yellow Report a call for detector proposals was announced with deadline for December 2021. Three detector conceptsare being developed with different approach to execute experimental program that aims to increase our understanding of the fundamental structure of all visible matter. This talk will present the general guidancefor the EIC detector with few examples of similarities and differencesin the proposals [Preview Abstract] |

G03.00002: Study of proton detection efficiency at Belle II John Stacy, Jake Bennett The Belle II experiment has recently started data taking at the SuperKEKB electron-positron collider in Tsukuba, Japan. Detector performance studies are necessary to understand early data and prepare for more complex analyses. This study of proton detection efficiency is useful for detector and calibration experts to better understand the data and for analysts exploring final states that include protons.

G03.00003: A study of $\gamma p \to K_SK_Sp$ with the GlueX Experiment Gabriel Rodriguez GlueX is a photoproduction experiment designed to study the meson spectrum with special emphasis on exotic quantum number mesons. Having completed its first phase of data collection, the GlueX Collaboration possesses a unique high statistics dataset that is currently under study. As part of the spectroscopy program we present our analysis of the $\gamma p \to K_SK_Sp$ reaction. Mesons decaying to $K_SK_S$ have $J^{PC}$ = even$^{++}$ and contributions from J = 0 and 2 are expected to dominate. Thus, studying the $K_SK_S$ system will contribute to our understanding of the light scalar and tensor mesons. The current state and future plans of this analysis will be presented.

G03.00004: Optimized Extraction of Generalized Parton Distributions from Deeply Virtual Compton Scattering Philip Velie, Zaki Panjsheeri, Krisean Allen, Brandon Kriesten, Simonetta Liuti \noindent Generalized Parton Distributions (GPDs) are a powerful tool that allows greater insight into the internal structure of the nucleon. GPDs define the matrix elements for the deeply virtual Compton scattering (DVCS) process [1]. I will first present a spectator model calculation for the quark, anti-quark and gluon chiral even GPDs $H,E, \widetilde{H},\widetilde{E}$ in terms of the kinematic variables X, $\zeta$, and $t$ [2]. The model implements the polynomiality and positivity constraints, and it is evolved in perturbative QCD up to next to leading order. I will then illustrate the implementation of computer tensor algebra methods to construct algorithms to optimize the analysis for DVCS, Bethe Heitler, and interference cross-section terms for various beam and target polarization in the formalism of Ref.[3]. \vspace{0.3cm} [Preview Abstract] |

G03.00005: Monte Carlo Study of B− → D0 τντ with Belle II Sakul Mahat, Tom Browder Belle II, the first super B-Factory experiment, is designed to make precise measurements of weak interaction parameters and find New Physics beyond the Standard Model of particle physics. One of the assumptions of the Standard Model is that the couplings of particles that mediate the weak force ( known as ‘W’ or ‘Z’ electroweak gauge bosons) to leptons occurs irrespective of their flavor. This fundamental assumption of Lepton Universality is tested in this study of B− → D0 τντ in Belle-II simulation. [Preview Abstract] |
