„Long-Lived Particle Searches at a Future Higgs Factory with the ILD experiment”

Referuje: mgr Jan Klamka (IFD UW)

Future e+e– colliders provide a unique opportunity for long-lived particle (LLP) searches. I will present a full simulation study of LLP searches using the International Large Detector (ILD), a detector concept for a future Higgs factory, with a gaseous time projection chamber as its main tracking device. Signatures of displaced vertices and kinked tracks are explored. Challenging final states involving both very soft displaced tracks and boosted, nearly collinear tracks have been studied. Backgrounds from beam-induced interactions and other Standard Model processes are considered. Expected exclusion limits will be presented for a model-independent analysis, as well as for Higgs boson decays to LLPs, for a range of LLP lifetimes.

„Recent  heavy flavour results from CMS”

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

The CMS experiment has delivered numerous significant measurements using data from LHC Run-2 and the ongoing Run-3. This report explains key components of the CMS detector relevant to heavy flavour physics. The short introduction to CP violation in Bs → J/ψϕ(1020) is given, followed by the recent CMS results, confirming the CP violation in this channel. The search for CP violation in Ds → Ks0 Ks0 channel is presented. In addition the most important information on selected recent CMS heavy flavour physics results is highlighted. It includes: measurement of Bs → J/ψKS effective lifetime, test of lepton flavour universality with RJ/ψ and search for rare decays in D0 → µ+ µ− . Finally the CMS measurements of B/Bs → µ+ µ− are reminded.
