WIDG Seminar: Avinay Bhat, Syracuse University, "MeV Scale Physics in MicroBooNE"

This talk presents the first measurement of sub-MeV scale energy signatures and relevant backgrounds for beam neutrino interactions in MicroBooNE using a dedicated reconstruction technique. After introducing the Liquid Argon Time Projection Chamber technology and the MicroBooNE detector, I will highlight the main features of this reconstruction technique and the measurements carried out from beam neutrino data.

WIDG Seminar: Gadi Afek, Yale, "Searches for New Physics Using Levitated Optomechanics"

In an attempt to provide further insight into one of the major questions of physics beyond the standard model, new, highly sensitive, optomechanical sensors are employed utilizing techniques synchronous with those of the atomic physics community. These sensors are table-top experimental tools offering exquisite control of mechanical and electrical degrees of freedom and isolation from the environment. They enable unprecedented acceleration sensitivities for ~ng objects, while still maintaining the access needed to probe short-ranged dynamics.

NPA Zoom Seminar, Kimmy Wu, SLAC/KIPAC, "Improved Constraint on Primordial Gravitational Waves with Delensing"

Inflation generically predicts a background of primordial gravitational waves, which generate a primordial B-mode component in the polarization of the cosmic microwave background (CMB). The measurement of such a B-mode signature would lend significant support to the paradigm of inflation. Observed B modes also contain a component from the gravitational lensing of primordial E modes, which can obscure the measurement of the primordial B modes.

NPA Zoom Seminar, Govert Nijs, MIT, "A Transverse Momentum Differential Global Analysis of Heavy Ion Collisions"

The understanding of heavy ion collisions and its quark-gluon plasma formation requires a complicated interplay of rich physics in a wealth of experimental data. In this work we compare for identified particles as a function of transverse momentum both the spectra and the anisotropic flow coefficients for both PbPb and pPb collisions. We do this in a model including a free streaming prehydrodynamic phase with variable velocity v_fs, thereby widening the scope of initial conditions. During the hydrodynamic phase we vary three new second order transport coefficients.

NPA Zoom Seminar, Zhilei Xu, MIT, "Precision Cosmology: from the CMB to 21-cm Observations"

Over the past decades, the discovery and characterization of the cosmic microwave background (CMB) have marked the beginning of precision cosmology. At lower redshifts, future 21-cm signals from neutral hydrogen atoms also have great potential for cosmological and astrophysical studies. Observing 21-cm signals at different frequency bands produces a tomographic view of the universe. These observations will transform our current understanding of cosmology, commencing the 21-cm precision cosmology.

NPA Zoom Seminar, Jean-Francois Paquet, Duke, "Constraining the Viscosities of QCD with Relativistic Heavy Ion Collisions"

Fluids can be characterized by macroscopic properties such as viscosities or an equation of state. While the macroscopic properties of everyday fluids are determined by the electromagnetic interaction, an ensemble of fluids encountered in astrophysics and nuclear physics is dominated by the strong nuclear interaction. Relativistic collisions of heavy nuclei, performed at the Large Hadron Collider and the Relativistic Heavy Ion Collider, concentrate sufficient energy at the point of impact to produce a strongly-coupled plasma of deconfined nuclear matter.
