The Leptoquark Hunter's Guide: Large Coupling

Martin Schmaltz, Yi-Ming Zhong

Leptoquarks have recently received much attention especially because they may provide an explanation to the and anomalies in rare meson decays. In a…

Linear Sigma EFT for Nearly Conformal Gauge Theories

T. Appelquist, R. C. Brower, G. T. Fleming +11

We construct a generalized linear sigma model as an effective field theory (EFT) to describe nearly conformal gauge theories at low energies. The work is motivated by recent lattic…

Constraining Dissipative Dark Matter Self-Interactions

Rouven Essig, Samuel D. McDermott, Hai-Bo Yu +1

We study the gravothermal evolution of dark matter halos in the presence of dissipative dark matter self-interactions. Dissipative interactions are present in many particle-physics…

Natural Stabilization of the Higgs Boson's Mass and Alignment

Kenneth Lane, William Shepherd

Current data from the LHC indicate that the 125 GeV Higgs boson, , is either the single Higgs of the Standard Model or, to a good approximation, an "aligned Higgs". We propose t…

Exploring Leptophilic Dark Matter with NA64-

Chien-Yi Chen, Jonathan Kozaczuk, Yi-Ming Zhong

We investigate the prospects for detecting light leptophilic dark sectors with a missing-momentum experiment at NA64 running in muon mode. In particular, we consider models in whic…

Cannibal Dark Matter and Large Scale Structure

Manuel A. Buen-Abad, Razieh Emami, Martin Schmaltz

Cannibals are dark matter particles with a scattering process that allows three particles to annihilate to two. This exothermic process keeps the gas of the remaining particles war…
