09:00 When Do Dark Bound States Matter?

Abstract: Dark matter may form bound states that subsequently decay producing Standard Model particles, enhancing and modifying the expected indirect signals from dark matter annihilation. The force carriers that support such bound states could be either new light particles, or the gauge bosons of the Standard Model. I will discuss the motivations for models containing dark matter bound states, the behavior of these systems in the general case where multiple force carriers and dark-matter-like particles are involved, and the implications for dark matter searches. I will present general results for bound states in weakly-coupled dark sectors, guidelines for estimating when bound state formation is important, and an example for supersymmetric wino dark matter.

13:40 Rare Physics at the Intensity Frontier

Next generation detector technology at future neutrino experiments are driven, in large, by the search for sterile neutrinos. In addition to their main research program, these experiments are sensitive to a number of rare neutrino physics processes. Neutrino trident production is one such process, which sees an incoming neutrino incident on a nucleus produce an outgoing neutrino and two oppositely charged leptons. The standard model rates at SHiP and DUNE allow for a number of trident mixed-flavour modes, most of which have never been observed. Some of these mixed-flavour modes have production cross sections as high as 35 times those previously considered by CHARM-II and CCFR, the latter of which currently provides the most stringent bound on certain Z’ models. Trident can also serve as a useful tool for probing generic leptophilic scalar extensions of the standard model. Time permitting, we also discuss hidden heavy neutral lepton extensions to the SM that could yield additional sources of single photons. Proposed as an exotic explanation to the MiniBooNE excess, these could be probed by Fermilab’s upcoming LArTPC short baseline program.

15:20 Search for new heavy bosons in the dilepton final state at CMS

The dilepton final state offers great sensitivity to the existence of new heavy bosons that would be visible as a peak in the invariant mass distribution of the two leptons. In this talks, results of a search for new physics in this final state will be discussed, with a focus on recent extension of the interpretation in different models of new physics.

Speaker: Jan-Frederik Schulte (Purdue University (US))

15:40 Exotica in Hadron Spectroscopy

The hadron spectrum contains many states which do not fit in the quark model description of hadrons. In this talk, I will discuss some phenomenological methods in identifying the nature of these exotic states. We use fundamental principles of scattering theory to model hadronic processes and test these methods against experimental data.
