Neutron Portal and Dark Matter-Baryon Coincidence: from UV Completion to Phenomenology

Sudhakantha Girmohanta, Yuichiro Nakai, Yoshihiro Shigekami +1

We present a dynamical solution to the dark matter-baryon coincidence problem based on the neutron portal operator connecting the visible and dark sector asymmetries. This framewor…

Magnetic monopoles and high frequency gravitational waves from quasi-stable strings

Rinku Maji, Qaisar Shafi

The spontaneous breaking of via flipped to the Standard Model yields a novel scenario in which the superheavy topologically stable GUT monopole carrying a single u…

Neutrino NSI in archaeological Pb

D. Alloni, G. Benato, P. Carniti +47

Dark matter direct detection experiments can observe solar neutrinos via coherent elastic neutrino-nucleus scattering, making it possible to test new physics in the neutrino sector…

Is a covariant virtual tachyon viable?

Krzysztof Jodłowski

Sidney Coleman has noted that superluminal particles or observers would be able to go back in time and have no definite trajectory according to subluminal observers, while not viol…

Superconducting Strings in

Rinku Maji, Qaisar Shafi

We discuss the appearance of superconducting strings in grand unification, keeping track of the magnetic monopole flux that precedes the formation of the string flux tube. Th…

New Bounds on Heavy QCD Axions from Big Bang Nucleosynthesis

Tae Hyun Jung, Takemichi Okui, Kohsaku Tobioka +1

We study Big Bang Nucleosynthesis (BBN) constraints on heavy QCD axions. BBN offers a powerful probe of new physics that modifies the neutron-to-proton ratio during the process, th…
