Plano de atividades:

Período : 10 a 24 de novembro de 2019 (15 dias)

• Seminar on the topic of Rare Decays.

Rare decays present a most sensitive means for detecting the presence of physics being the standard model (BSM) at the LHC. The high-luminosities planned for the accelerator in the coming runs, also considering the absence of unambiguous BSM signals through directly searches in the two first runs of the LHC, render the exploration of rare processes especially promising. Rare decays of heavy quarks, vector bosons, tau leptons, and the Higgs boson can all be probed at the LHC and shall be most actively pursued in the upcoming runs.

• Discussions and lectures on the topic of B Physics

Heavy flavour physics allow precision tests of the SM and to test the presence of BSM physics up to scales beyond those accessible via direct searches. Flavour mixing and rare decays offer particularly sensitive processes. Tests of lepton flavour universality have recently yielded the most significant departures from the SM yet. Heavy flavour further provide sensitive processes to improve our understanding of QCD. They allow to probe the underlying mechanisms of hadron production in elementary collisions and facilitate novel probes for studying the behavior and properties of QCD matter at the highest densities and temperatures through phenomena such as hadron melting and parton energy loss.

• Cooperation in data analysis of the CMS experience.

During the stay, existing collaboration projects between UERJ and LIP will be advanced and new ones fostered. The measurement of decays of the Higgs boson to quarkonia with Run2 data are both highly sensitive and most timely goals that shall be advanced. New (so-called parked) datasets offer unbiased samples that give access to processes that were not accessible before with CMS. New trigger paths, especially novel ones to be prepared, will similarly determine the physics reach of the upcoming LHC Run3.
