I will go through the list of new physics search results at the LIGO-Virgo-KAGRA collaborations, which includes searches for early universe phase transitions, topological defects, searches for various species of dark matter, etc.

The nature of dark matter (DM) remains one of the most critical challenges in modern physics. Macroscopic DM present a compelling alternative to conventional particle DM, yet their terrestrial

This talk gives a unified perspective on the phase transitions, gravitational waves, and dark matter detection prospects of strongly coupled dark sectors. I first review lattice-informed effective descriptions of dark confinement and chiral dynamics, and show how the resulting first-order transitions generate observable gravitational wave signals, strongest in the near-conformal, strongly...

It is well known that unbroken global symmetries of the lagrangian remain unbroken under RG evolution. Less appreciated is the fact that certain relations can be RG-stable even without any symmetry transformation of the field content of the model. Recently, a renewed interest in this topic was sparked by the observation of a family of all-order RG-stable relations in the 2HDM scalar sector...

3-form dark energy is similar to but distinguishable from a scalar field in an expanding universe, and its tensorial structure allows for unique couplings that cannot be experienced by canonical scalars. We here explore the possibility that 3-form dark energy can explain the cosmic birefringence angle $\beta\sim0.3^\circ$, as suggested by observations of the CMB polarization. We consider two...

Dark matter could consist mainly of magnetic monopoles of a dark non-abelian gauge group. These dark monopoles could be produced during a thermal phase transition in the early Universe. We show that, in a minimal model and with quite general assumptions, this scenario cannot be realized, since the dark matter abundance is always dominated by dark gauge bosons. In a non-minimal extension of the...

Recent years, the intensity frontier of physics beyond the Standard model attracts more and more attentions. Thus light long lived particles searches becomes critical, and the various new machines like FASER, ShiP, Mathusla are built up or proposed. In this talk we study the prospect of detecting light long-lived Higgs at these machines. We develop the general formalism for the scalar...

Heavy neutral leptons (HINLs) provide a minimal and testable origin of neutrino masses and cangenerate the baryon asymmetry through low-scale leptogenesis. Their small active sterile mixinghowever, makes much of the theoretically motivated parameter space inaccessible to existing experimentsWe show that a future high-energy muon facility can operate as a heavy-neutrino factory and muon...
