While di-Higgs production has long been of interest, in scalar extensions of the Standard Model multi-scalar production beyond di-Higgs can be interesting. In this talk I will discuss some signatures of resonant multi-scalar production, focusing on the complex singlet extension of the Standard Model in particular.
The direct detection of sub-GeV dark matter (DM) remains a significant challenge due to the low recoil energies involved. In this talk, we focus on the scattering rate of sub-GeV DM particles interacting via spin-dependent couplings with nucleons, in solid-state targets. For DM masses below 100 MeV, the dominant scattering process involves incoherent multiphonon production, which offers a...
A B-mode polarization signal in the cosmic microwave background (CMB) is widely regarded as smoking gun evidence for gravitational waves produced during inflation. Here we demonstrate that tensor perturbations from a cosmological phase transition can produce a B-mode signal whose strength rivals that of testable inflationary predictions across a range of observable scales. Although phase...
