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,…
An EFT approach to the study of multi-phase criticality scenarios
Kristjan Kannike, Luca Marzola, Kristjan Müürsepp
Multi-phase critical scenarios explain the observed Higgs boson mass scale by the almost simultaneous occurrence of two smoothly connected phases of the theory, which differ by the…
Is our vacuum global in a 331 model with three triplets?
Kristjan Kannike, Niko Koivunen, Aleksei Kubarski
We consider a 331 model, based on , with three triplets with a softly broken symmetry. The resulting scalar potential is commonly used in phen…
Dark matter in the scale-invariant 3-3-1-1 model
Alex G. Dias, Kristjan Kannike, Niko Koivunen +3
We propose a novel scale-invariant model with the 3-3-1-1 gauge symmetry featuring a universal see-saw mechanism for all fermion masses, which, through the inclusion of additional…
Rebuttal of 'Note on "Vacuum stability of a general scalar potential of a few fields"'
Kristjan Kannike
We show that the recent 'Note on "Vacuum stability of a general scalar potential of a few fields"' [arXiv:2401.13863] erroneously misses the possibility that the Higgs portal term…
Phase Transitions and Gravitational Waves in a Model of Scalar Dark Matter
Nico Benincasa, Andrzej Hryczuk, Kristjan Kannike +1
Theories with more than one scalar field often exhibit phase transitions producing potentially detectable gravitational wave (GW) signal. In this work we study the semi-annihilatin…
