11. Common origin of neutrino mass, dark matter and Dirac leptogenesis / Borah, Debasish ; Dasgupta, Arnab
We study the possibility of generating tiny Dirac neutrino masses at one loop level through the scotogenic mechanism such that one of the particles going inside the loop can be a stable cold dark matter (DM) candidate. [...]

12. Toward (finally!) ruling out Z and Higgs mediated dark matter models / Escudero, Miguel ; Berlin, Asher ; Hooper, Dan ; Lin, Meng-Xiang
In recent years, direct detection, indirect detection, and collider experiments have placed increasingly stringent constraints on particle dark matter, exploring much of the parameter space associated with the WIMP paradigm [...]

13. Gravitational leptogenesis in axion inflation with SU(2) gauge field / Maleknejad, Azadeh
We present an intrinsic leptogenesis mechanism in models of axion inflation with a classical SU(2) gauge field. [...]

14. The Liouville equation for flavour evolution of neutrinos and neutrino wave packets / Hansen, Rasmus Sloth Lundkvist ; Smirnov, Alexei Yu.
We consider several aspects related to the form, derivation and applications of the Liouville equation (LE) for flavour evolution of neutrinos. [...]

15. Cosmology with a light ghost / Ivanov, Mikhail M. ; Tokareva, Anna A.
We study the creation and evolution of cosmological perturbations in renormalizable quadratic gravity with a Weyl term. [...]

16. Modifications to cosmological power spectra from scalar-tensor entanglement and their observational consequences / Bolis, Nadia ; Albrecht, Andreas ; Holman, R.
We consider the effects of entanglement in the initial quantum state of scalar and tensor fluctuations during inflation. [...]

17. Anisotropic non-gaussianity from rotational symmetry breaking excited initial states / Ashoorioon, Amjad ; Casadio, Roberto ; Koivisto, Tomi
If the initial quantum state of the primordial perturbations broke rotational invariance, that would be seen as a statistical anisotropy in the angular correlations of the cosmic microwave background radiation (CMBR) temperature fluctuations. [...]

18. Scale genesis and gravitational wave in a classically scale invariant extension of the standard model / Kubo, Jisuke ; Yamada, Masatoshi
We assume that the origin of the electroweak (EW) scale is a gauge-invariant scalar-bilinear condensation in a strongly interacting non-abelian gauge sector, which is connected to the standard model via a Higgs portal coupling. [...]

19. Entangled scalar and tensor fluctuations during inflation / Collins, Hael ; Vardanyan, Tereza
We show how the choice of an inflationary state that entangles scalar and tensor fluctuations affects the angular two-point correlation functions of the T, E, and B modes of the cosmic microwave background. [...]
