Abstracts of Talks

Bhubhanjyoti Bhattacharya Department of Natural Sciences Lawrence Technological University Puzzles in B-meson Decays Heavy meson decays provide optimal testing grounds for theories beyond the Standard Model of particle physics. In this talk, I will discuss a handful of recently uncovered puzzles in decays of heavy B mesons that may shed greater light on the “flavor tail” of new physics.

Likun Zhang and Cecille Labuda Department of Physics and Astronomy University of Mississippi; Physical Acoustics and Fluid Dynamics Likun Zhang and Cecille Labuda will give a general overview of their research in physical acoustics and fluid dynamics. The talk will cover complex fluids, biomedical applications of ultrasonics, ocean, physics, fluid physics and “ acoustofluidics”.

Xiaoyan Huang Department of Physics and Astronomy University of Mississippi TMS charge ID in the DUNE experiment An introduction to the DUNE experiment, TMS of the near detector system, its role in the reconstruction of muon track and charge identification..

Bhupal Dev Department of Physics Washington University in Saint Louis Seeing the Invisible: Neutrino-Dark Matter Interactions Neutrinos and dark matter remain two of the least known sectors of fundamental physics. Although both are “invisible” particles, we argue that a sizable interaction between them can leave footprints in several experimental observables. We implement the full catalog of constraints coming from cosmological and astrophysical datasets, as well as derive new laboratory constraints from meson and Z-boson decays. We then study the prospects of detecting neutrino-dark matter interactions in future galactic supernovaneutrino events at large-volume neutrino experiments, such as DUNE.

James Friend Center for Medical Devices University of California — San Diego Acoustic Streaming The analysis and use of acoustic streaming has taken on new urgency in the past few years with the recognition that classical analysis methods are unable to accurately quantify the flows generated by passing acoustic waves beyond a few hundred kHz. This issue, known since at least Lighthill’s namesake publication in the 1970s, has not been addressed in the time since, with many researchers—including the author—resorting to computational analysis and approximations to overcome at least some of the problems. Moreover, few researchers have been willing to consider the dynamic behavior of acoustic streaming: the delayed onset, the response to inharmonic excitation, and the delayed flows after the acoustic wave ceases, though these aspects are important in many experiments. Much of the reason is the challenge of the analysis of such flows. After considerable work via an alternative analysis path, we may finally have arrived at a method for closed-form analysis of acoustic streaming at least in one dimension, with transient behavior and both nonlinear compressibility and viscous effects included. We present a coherent and straightforward plan for analyzing simple acoustic streaming cases where classic theories fall short.
