Boosted dark particles and the LZ nuclear recoil event

Kristjan Kannike, Martti Raidal, Alessandro Strumia

The LZ experiment reported one anomalous event with nuclear recoil energy of 248 keV. Galactic halo dark matter (DM) cannot produce such a large energy unless heavier than 74 GeV,…

Energy-scaling behavior of intrinsic transverse momentum parameters in Drell-Yan simulation

CMS Collaboration

An analysis is presented based on models of the intrinsic transverse momentum (intrinsic ) of partons in nucleons by studying the dilepton transverse momentum in Drel…

Probing sterile neutrino freeze-in at stronger coupling

Niko Koivunen, Oleg Lebedev, Martti Raidal

The regime of dark matter (DM) freeze-in at stronger coupling interpolates between freeze-in and freeze-out. It relies on Boltzmann-suppressed dark matter production, implying that…

Explaining the excess via a massless dark photon

E. Gabrielli, L. Marzola, K. Müürsepp +1

The Belle II collaboration has recently observed the rare decay , finding an excess with respect to the Standard Model prediction. We explore the possibility tha…

Production and decays of 146 GeV flavons into final state at the LHC

Niko Koivunen, Martti Raidal

The CMS experiment at CERN has reported a possible signal for a resonance at 146 GeV decaying into the final state which, presently, is the only experimental hint for lepton f…

Non-supersymmetric SO(10) models with Gauge and Yukawa coupling unification

Abdelhak Djouadi, Renato Fonseca, Ruiwen Ouyang +1

We study a non-supersymmetric SO(10) Grand Unification Theory with a very high energy intermediate symmetry breaking scale in which not only gauge but also Yukawa coupling unificat…
