prof. dr hab. Bohdan Grządkowski profesor
Wydział Fizyki
Dyscyplina naukowa:
nauki fizyczne
Zainteresowania badawcze:
- Teoretyczna fizyka cząstek elementarnych, w szczególności uogólnienia Modelu Standardowego takie jak np. naruszenie symetrii CP.
- Kosmologia cząstkowa, w szczególności modele ciemnej materii oraz inflacja.
description of research interests:
- Theoretical particle physics, in particular generalizations of the Standard Model such as e.g. violation of the CP symmetry.
- Particle cosmology, in particular models of dark matter and inflation.
Realizowane projekty:
- Dark matter is detected only through gravitational interactions, we are showing that no other interactions of dark matter are needed. This kind of dark matter may be easily produced through gravitational interactions during inflation and reheating periods. The production mechanism is a quantum process that takes place in quickly varying gravitational backgrounds.
- We have noticed divergent amplitudes in certain annihilation processes of dark matter. There is no known method to regularize these singularities. We are trying to understand these intriguing phenomena.
- Symmetries quantum field theories provide very important tools while studding extensions of the Standard Model. We are trying to formulate a strategy that would allow to test, in terms of physical observables, all symmetries of the 2-Higgs doublet extension of the Standard Model.
- We are investigating scenarios in which the strength of interaction between dark matter and the Standard Model is naturaly very weak.
