SEMINARIUM FIZYKI WIELKICH ENERGII

Dnia 1 grudnia (piątek) o godzinie 10:15, w sali B2.38 odbędzie się seminarium, na którym zostanie wygłoszony referat pt.:

„Neutrino oscillations – review of current experimental results”

Referuje: dr hab. Justyna Łagoda, prof NCBJ

The existence of neutrino oscillations was confirmed 25 years ago.

Since that time, a lot of experiments have been performed with different sources of neutrinos and detection techniques.

Now, we know the values of the neutrino mixing angles with quite good precision, yet there are still questions to be answered, such as the neutrino mass ordering, CP-violation in the neutrino sector, or the existence of sterile neutrinos. The presentation is an extended and updated talk given at the EPS HEP 2023 conference and will summarize the current knowledge of neutrino oscillations and present recent results from selected experiments as well as some perspectives for the future.

SEMINARIUM FIZYKI WIELKICH ENERGII

Dnia 24 listopada (piątek) o godzinie 10:15, w sali B2.38 odbędzie się seminarium, na którym zostanie wygłoszony referat pt.:

„The LUXE – Laser und XFEL Experiment – Report from the “LUXE physics and SFQED workshop” and LUXE Collaboration Meeting”

Referuje: dr hab. Grzegorz Grzelak (IFD,UW)

In the seminar I will present the progress in the preparation of the LUXE experiment after publishing in 2023 the TDR:

Technical Design Report.

LUXE is an experiment currently being developed at DESY in Hamburg, that aims to use the high-quality electron beam of the European XFEL facility and a high-power optical laser.

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

SEMINARIUM FIZYKI WIELKICH ENERGII

Dnia 17 listopada (piątek) o godzinie 10:15, w sali B2.38 odbędzie się seminarium, na którym zostanie wygłoszony referat pt.:

„Heavy flavour physics 2.0 (LHCb Upgrades)”

Referuje: dr hab. Agnieszka Obłąkowska-Mucha, prof AGH (AGH)

LHCb has undergone a major upgrade during LHC LS2 (2019-2022) to cope with increased instantaneous luminosities, a full software-based trigger, and real-time analysis. This talk will include the very fresh LHCb results, the performance of the real-time readout system, and plans for the long-lived particle reconstruction. Further upgrades and reconstruction challenges for LHC Run 4 and 5 will also be discussed.

SEMINARIUM FIZYKI WIELKICH ENERGII

Dnia 10 listopada (piątek) o godzinie 10:15, w sali B2.38 odbędzie się seminarium, na którym zostanie wygłoszony referat pt.:

„The Level-1 muon trigger of the CMS experiment”

Referuje: dr hab. Marcin Konecki, prof. UW (IFD UW)

The event selection in the CMS experiment is necessary to reduce the LHC event rate down to O(1kHz) suitable for event storage.

This selection is done by the two stage trigger. The CMS level-1 muon trigger, is custom-hardware device, processing signals from CMS muon detectors.

In the presentation the evolution and the performance of the Level-1 muon trigger system is discussed.

The perspectives for upgrade for LHC Phase-II are given.

The activities of Warsaw Group, responsible for the trigger operation in a barrel-endcap overlap of the CMS detector, are emphasized.
