Establishment of reasonable model to simulate emergency passive coolant system in HTTR reactor
2020.11.24 14:59 - Anna RędaszekInternational Atomic Energy Agency (IAEA) Coordinated Research Program (CRP) on "Heat Transport and Afterheat Removal for Gas-cooled Reactors under Accident Conditions" started in November 1993. In this program, benchmark tasks were proposed for the analysis of passive afterheat removal from gas-cooled reactors (GCR) under accident conditions.

Feasibility Studies of CPT Violation Measurement in Flavour Oscillations of the Neutral D Meson
2020.11.10 14:55 - Katarzyna KuźniarMesons are bound quark-antiquark pairs. Flavoured neutral mesons are defined as mesons with no electric charge and non-zero strangeness, charm or beauty content. The weak interactions mix neutral-mesons with their antiparticles leading to spontaneous transitions between meson and antimeson quantum states, which can serve as a sensitive interferometer facilitating precision testing of CPT invariance.

CP violation in the Minimal Linear sigma Model
2020.11.03 22:36 - Anna RędaszekIn this seminar we review the generalities of composite Higgs (CH) models that aim to solve the Standard Model hierarchy problem with the introduction of the Higgs as a Nambu-Goldstone boson as well as a new strong sector with new heavy particles. In particular we work with a renormalizable CH model, the Minimal Linear sigma model (MLsM). The phenomenology of this model is extended with the study of the electron electric dipole moment (eEDM) in accordance with the experimental constraints furnished by the ACME Collaboration in order to set limits on the MLsM CP-violating phases.

Aspects of Lorentz and CPT violation in Cosmology
2020.06.30 13:17 - Anna RędaszekThe breaking of Lorentz symmetry can give rise to a wealth of observational consequences. In this talk I will summarise the work which comprises my PhD thesis. In a nutshell, my goal was to explore models of gravitation and cosmology with Lorentz symmetry violation. Five Lorentz-violating models or frameworks are outlined in this talk, and three of these are subsequently chosen and studied. Doubly General Relativity breaks Lorentz symmetry through a modification of the dispersion relation of particles.

Brief introduction to X-Ray photoelectron spectroscopy (XPS) with some examples
2020.06.02 11:00 - Anna RędaszekX-ray photoelectron spectroscopy (XPS), also known as Electron Spectroscopy for Chemical Analysis (ESCA), is an analysis technique used to obtain chemical information about the surfaces of solid materials. Typical measurements include chemical composition, oxidation state analysis, identification of species, surface reactions, imaging of patterned surfaces and deposits. In methods of ‘classical’ X-ray electron spectroscopy, the energy distribution of electrons knocked out of a sample by X-ray radiation is measured.

One Loop Renormalization Of Non-Commutative Wess Zumino Model
2020.05.26 12:02 - Anna RędaszekWe consider the effective potential for Wess Zumino model. By using renormalization group equation we show the explicit dependence of the divergent term get removed. We have also shown that for this case SUSY is unbroken.
