Sensitivity targets for dark photon searches in charged kaon decays

M. Fabbrichesi, E. Gabrielli, K. Müürsepp

We investigate the prospects for detecting invisible dark photons in charged kaon decays through the two-pion channel and the one-pion radiative decay $K^+\toπ^…

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…

Fuzzy dark matter fails to explain the dark matter cores

María Benito, Gert Hütsi, Kristjan Müürsepp +4

Ultrafaint dwarf galaxies (UFDs) are ideal for studying dark matter (DM) due to minimal baryonic effects. UFD observations suggest cored DM profiles. We find that the core radius -…

On the viability of the QCD axion - dark energy transition

Kristjan Müürsepp

This conference thesis summarizes my presentation at Tartu Tuorla Cosmology meeting based on a collaborative work with E.Nardi and C.Smarra \cite{Muursepp:2024mbb}. It is well know…

Accelerated cosmic expansion, mass creation, and the QCD axion

Kristjan Müürsepp, Enrico Nardi, Clemente Smarra

We propose a mechanism in which the current acceleration of cosmic expansion is driven by continuous creation of energy density for a certain field . We accordingly modi…

An effective field theory of the Delta-resonance

Juan Carlos Criado, Abdelhak Djouadi, Niko Koivunen +3

We present an effective field theory of the -resonance as an interacting Weinberg's field in the multi-spinor formalism. We derive its interactions with…

Confronting spin-3/2 and other new fermions with the muon g-2 measurement

Juan C. Criado, Abdelhak Djouadi, Niko Koivunen +3

The new measurement of the muon's anomalous magnetic moment released by the Muon g-2 experiment at Fermilab sets strong constraints on the properties of many new particles. Using a…
