The 10th LCTP Spring Symposium : Hunting for Particle Dark Matter

→ US/Eastern
University of Michigan, Ann Arbor West Hall (Room 340)
Aaron Pierce (University of Michigan), Christian Herwig (Umich), Scott Haselschwardt (Umich)
Description

May 5th – 7th, 2025 in 340 West Hall

The Physics Department at the University of Michigan supported by The Leinweber Center for Theoretical Physics will host the 10th LCTP Spring Symposium: Hunting for Particle Dark Matter.

A primary goal of this program will be to bring together theorists and experimentalists. We anticipate having people representing the direct detection, collider, and fixed target communities, and hope that there will be fruitful discussions between them.

The workshop will be on May 5th – 7th, 2025, with talks ending near midday on the 7th and a reception on the evening of the 5th. However, participants will be welcome to stay later in the week for additional interaction as desired. There will be no registration fee. Participants should register for planning purposes.

      Direct Detection With Magnons

      To directly detect dark matter significantly lighter than a GeV, experiments must utilize the sub-eV energy excitations in condensed matter systems. Phonons, collective excitations of lattice vibrations, naturally have energies in the 1-100 meV range and are promising targets for spin-independent dark matter interactions. However, their response is generally suppressed for spin-dependent dark matter couplings. In such cases, magnons, collective excitations of spin waves, offer a more favorable detection pathway, exhibiting similar kinematic properties to phonons but enhanced sensitivity to spin-dependent interactions. In this talk we'll discuss calculating the dark matter-magnon scattering rate from both a first-principles approach and a data-driven approach using neutron scattering data collected with the MAPS spectrometer at the ISIS Neutron and Muon Source. Additionally, we'll explore how magnons can also be used to search for electron-coupled axion dark matter.

      Dark QCD: the Next Frontier in Dark Matter

      There has been a surge of interest in hidden valley models with new, strong forces, sometimes called "dark QCD". These models propose asymmetric, composite dark matter in the form of "dark hadrons" that would evade direct and indirect bounds as well as typical collider DM searches for large missing transverse momentum accompanied by radiation. However, evidence of these models can still be found in collider datasets by targeting their unique phenomenological signatures, which include semivisible jets, emerging jets, and soft unclustered energy patterns. We will present the latest experimental results for these signatures and discuss the significant strides in exploring the vast space of dark QCD models. We will further discuss the prospects for dramatic expansions in sensitivity via machine learning.
