ABSTRACT:

The REDTOP experiment is a super-η/η′ factory aiming at exploring physics BSM, and Cold Dark Matter in particular, in the MeV-GeV energy range. This range is, at present, the most unconstrained among the energy regions searched by current and planned experiments. The η and η′ mesons are almost unique in the particle universe. Their quantum numbers are all zero, which occurs only for the Higgs boson and the vacuum (except for parity). In that respect, REDTOP is considered a low-energy Higgs factory. Furthermore, less than 80REDTOP aims at collecting more than 1014 eta/yr (1012 eta’/yr) in a 3-year running period, corresponding to about five order of magnitude of the current world sample. Such statistics is sufficient for investigating several symmetry violations, and for searching particles and forces beyond the Standard Model, including dark matter, by studying rare decays of the η and η′. Recent physics and detector studies indicate that REDTOP has excellent sensitivity to probe all four portals connecting the dark sector with the Standard Model, a feature reached only by the SHIP experiment at CERN. Furthermore, conservation laws and violation of discrete symmetries can be probed in several ways. REDTOP is the only η/η′ factory being proposed in the world. The advanced design of the detector is the key of the experiment. A modest proton beam with low power (30 W) is required. Recent physics and detector studies indicate that REDTOP has excellent sensitivity to probe all four portals connecting the dark sector with the Standard Model. Furthermore, conservation laws and violation of discrete symmetries can be probed in several ways. The physics program and the detector for REDTOP will be discussed during the presentation.

"Voxelated Bioprinting: Digital Assembly of Viscoelastic Bio-ink Particles"


Liheng Cai , University of Virginia
[Host: Bellave Shivaram]
ABSTRACT:

Analogues of pixels to two-dimensional (2D) pictures, voxels –– in the form of small cubes or spheres –– are the basic units of three-dimensional (3D) objects. Digital assembly of bio-ink voxels may provide an approach to engineering heterogeneous yet tightly organized 3D tissue mimics. However, this approach requires precisely manipulating highly viscoelastic bio-ink voxels in 3D space, which represents a grand challenge in both soft matter science and biomanufacturing. In this talk, I will introduce a voxelated bioprinting technology that enables the Digital Assembly of Spherical bio-ink Particles (DASP). First, I will discuss the criteria for the on-demand generation, disposition, and assembly of viscoelastic bio-ink droplets in an aqueous environment without the help of large interfacial tension. Second, I will describe how to use DASP to create 3D structures consisting of interconnected yet distinguishable bio-ink particles. Finally, I will share our recent progress in applying DASP to encapsulate islets into multiscale porous scaffolds to treat type 1 diabetes. I will also discuss immediate applications and emerging challenges associated with voxelated bioprinting.

"Dumb Machine Learning for Physics"


Yonatan Kahn , University of Illinois at Urbana-Champaign
[Host: Craig Dukes]
ABSTRACT:

Machine learning is now a part of physics for the foreseeable future, but many deep learning tools, architectures, and algorithms are imported from industry to physics with minimal modifications. Does physics really need all of these fancy techniques, or does “dumb” machine learning with the simplest possible neural networks suffice? I will argue that the needs for interpretability and uncertainty quantification in physics applications of machine learning mitigate toward the use of simpler tools with more predictable performance. I will give several examples illustrating how tools imported from physics may be used to better understand the training dynamics of fully-connected networks, and conversely, how the topology and geometry of collider physics data may be used as a testbed for theories of machine learning relevant for data “in the wild”.
