New fermions in the light of the
J. C. Criado, A. Djouadi, N. Koivunen +3
The very precise measurement of the anomalous magnetic moment of the muon, recently released by the Muon g-2 experiment at Fermilab, can serve to set stringent constraints on new p…
Primordial black holes from spectator field bubbles
David Navidad Maeso, Luca Marzola, Martti Raidal +2
We study the evolution of light spectator fields in an asymmetric polynomial potential. During inflation, stochastic fluctuations displace the spectator field from the global minim…
Tachyonic Preheating in Plateau Inflation
Eemeli Tomberg, Hardi Veermäe
Plateau inflation is an experimentally consistent framework in which the scale of inflation can be kept relatively low. Close to the edge of the plateau, scalar perturbations are s…
Prospects for probing gravitational waves from primordial black hole binaries
Oriol Pujolas, Ville Vaskonen, Hardi Veermäe
We study the prospects of future gravitational wave (GW) detectors in probing primordial black hole (PBH) binaries. We show that across a broad mass range from to…
Cosmological black holes are not described by the Thakurta metric: LIGO-Virgo bounds on PBHs remain unchanged
Gert Hütsi, Tomi Koivisto, Martti Raidal +2
We show that the physical conditions which induce the Thakurta metric, recently studied by Bœhm {\it et al.} in the context of time-dependent black hole masses, correspond to a sin…
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…
Higher-spin particles at high-energy colliders
Juan Carlos Criado, Abdelhak Djouadi, Niko Koivunen +2
Using an effective field theory approach for higher-spin fields, we derive the interactions of colour singlet and electrically neutral particles with a spin higher than unity, conc…
