Primordial black hole compaction function from stochastic fluctuations in ultra-slow-roll inflation
Sami Raatikainen, Syksy Rasanen, Eemeli Tomberg
We study the formation of primordial black holes (PBH) with ultra-slow-roll inflation when stochastic effects are important. We use the formalism and simplify the stochastic e…
Performance of the electromagnetic and hadronic prototype segments of the ALICE Forward Calorimeter
M. Aehle, J. Alme, C. Arata +74
We present the performance of a full-length prototype of the ALICE Forward Calorimeter (FoCal). The detector is composed of a silicon-tungsten electromagnetic sampling calorimeter…
Tree-level unitarity in Higgs inflation in the metric and the Palatini formulation
Asuka Ito, Wafaa Khater, Syksy Rasanen
We calculate the tree-level amplitudes for electrically neutral scattering for the Standard Model Higgs doublet non-minimally coupled to the Ricci scalar. We consider both…
Inflation with terms in the Palatini formulation
Jaakko Annala, Syksy Rasanen
We study inflation with the most general non-degenerate gravitational action that depends on the symmetric part of the Ricci tensor coupled to a scalar field in the Palatini formul…
Critical point Higgs inflation in the Palatini formulation
Vera-Maria Enckell, Sami Nurmi, Syksy Rasanen +1
We study Higgs inflation in the Palatini formulation with the renormalisation group improved potential in the case when loop corrections generate a feature similar to an inflection…
Higgs inflation and teleparallel gravity
Sami Raatikainen, Syksy Rasanen
Teleparallel gravity is a formulation of general relativity that is physically equivalent to metric gravity if the gravitational action has the Einstein-Hilbert form and matter is…
