SEMINARIUM FIZYKI WIELKICH ENERGII

Dnia 24 stycznia (piatek) o godzinie 10:15, w sali B2.38 odbedzie sie seminarium, na ktorym zostanie wygloszony referat pt.:

The LUXE – Laser und XFEL Experiment – era of strong fields QED.

Referuje: dr hab. Grzegorz Grzelak (IFD UW)

The seminar will introduce LUXE, „Laser Und XFEL Experiment”, currently being developed at DESY in Hamburg, an experiment that aims to use the high-quality electron beam of the European XFEL and a high-power laser.

The scientific goal of the experiment is to study quantum electrodynamics in the largely unexplored territory, in the regime of strong fields, close to and beyond the Schwinger limit, revealing the non-perturbative face of QED.

In the seminar the scientific case of the experiment will be presented.

In particular the details of the nonlinear Compton scattering and nonlinear Breit-Wheeler pair production.

The second part will cover the experimental setup of beam extraction from the European XFEL Linac, the requirements for a powerful laser and precise detectors optimized to measure electrons, positrons and photons.

CP violation in the neutrino sector: Recent long-baseline experiments results

Referuje: mgr Grzegorz Żarnecki (NCBJ)

The violation of CP symmetry in the neutrino sector may be manifested in different oscillation probabilities for neutrinos and antineutrinos. Long-baseline neutrino experiments search for this effect by studying electron (anti)neutrino appearance in primordial muon (anti)neutrino beam. In this talk T2K and NOvA experiments will be presented and their recent results on CP violation will be shown. Future experiments – DUNE and Hyper-Kamiokande – will also be discussed.

Upgrade of the NA61/SHINE experiment

Referuje: mgr Piotr Podlaski (IFD)

NA61/SHINE is a fixed target experiment located in the North Area of the CERN SPS accelerator. The main goal of the NA61/SHINE after Long Shutdown 2 at CERN (LS2, 2019-2021) is to measure open charm production in Pb+Pb interactions at SPS energies. To accomplish this, NA61/SHINE detection system undergoes a major hardware upgrade. The main purpose of the upgrade is to increase the readout rate up to 1 kHz and increase acceptance in the high density tracks environment. In this seminar I will discuss physics prospects for NA61/SHINE beyond LS2, I will also present status and plans of the upgrade.
