Niniejsza praca dotyczy badania klasy podwójnie powabnych rozpadów z dziwnością B -> D^(*)D^(*)_s(J). Pomiary przeprowadzono w oparciu o rozkłady masy brakującej w inkluzywnych przejściach B ->D^(*)X, a zatem w sposób wolny ...

The thesis describes searches for baryon and lepton number violation in X b → K−µ + (X b = Λ b , Ξ 0 b ) decays. The study is performed in the LHCb experiment using data sample corresponding to an integrated luminosity ...

The thesis describes searches for charged lepton flavour violation in the process τ−→ μ−μ+μ−. The study is performed at the LHCb experiment data sample corresponding to an integrated luminosity of 3 fb-1 of proton-proton ...

The thesis describes the world-first, time-dependent measurement of charge-parity (CP ) violation in B 0 s → D∓ s K± decays. The study is performed at the LHCb experiment using data sample corresponding to an integrated ...
