Dark Matter and the XENON1T electron recoil excess
Kristjan Kannike, Martti Raidal, Hardi Veermäe +2
We show that the electron recoil excess around 2 keV claimed by the Xenon collaboration can be fitted by DM or DM-like particles having a fast component with velocity of order $\si…
UV Freeze-in in Starobinsky Inflation
Nicolás Bernal, Javier Rubio, Hardi Veermäe
In the Starobinsky model of inflation, the observed dark matter abundance can be produced from the direct decay of the inflaton field only in a very narrow spectrum of close-to-con…
The EDGES 21 cm Anomaly and Properties of Dark Matter
Sean Fraser, Andi Hektor, Gert Hütsi +8
The recently claimed anomaly in the measurement of the 21 cm hydrogen absorption signal by EDGES at , if cosmological, requires the existence of new physics. The possible…
Vacuum Stability and Perturbativity of SU(3) Scalars
Matti Heikinheimo, Kristjan Kannike, Florian Lyonnet +3
We calculate the vacuum stability conditions and renormalisation group equations for the extensions of standard model with a higher colour multiplet scalar up to the representation…
Implications of effective axial-vector coupling of gluon for spin polarizations at the LHC
E. Gabrielli, A. Racioppi, M. Raidal +1
We analyze the impact of effective axial-vector coupling of the gluon on spin polarization observables in pair production at the LHC. Working at leading order in QCD, we…
