LHCb is one of the four experiments at the Large Hadron Collider (CERN), dedicated to the study of b-hadrons. Throughout my research, I studied in particular b-baryons which are abundantly produced at the LHCb. My habilitation summarises…

We report results from five analyses based on data taken with the BABAR detector at the PEP-II asymmetric e+e- collider. Included are branching fraction measurements for many B-meson decays involving eta, eta', omega, phi or a0 mesons and…

A search for CP(T) violation is performed and the fractional difference between the $b$ and $\bar b$ hadron lifetimes is measured using reconstructed secondary vertices in inclusive B hadron decays culled from 3.1 million $Z^0 \to q \bar q$…

We consider weak decays of heavy hadrons (bottom and charmed) where the heavy quark acts as a spectator. Theses decays are heavily phase-space suppressed but may become experimentally accessible in the near future. These decays are…

I discuss the heavy quark expansion for the inclusive widths of heavy-light hadrons, which predicts quite well the experimental ratios of B_q meson lifetimes. As for $\Lambda_b$, current determinations of ${\cal O}(m_b^{-3})$ contribution…

LHCb is an experiment dedicated to study CP violation and other rare phenomena in B mesons decays with very high precision. It is one of the four experiments that will operate at the 14Tev proton-proton Large Hadron Collider (LHC) at CERN…

Progress in the theoretical description of B-meson decays, in particular decays to light hadrons, is reviewed. The factorization properties of such decays can be analyzed using the soft-collinear effective theory. Applications of the…

A compact review of the theory, including some recent developments, of inclusive weak decay rates of charmed and b hadrons with an emphasis on predictions that can be tested in the forthcoming experiments.

Many topics are discussed in b physics including lifetimes, decay mechanisms, determinations of the CKM matrix elements |V_{cb}| and |V_{ub}|, facilities for b quark studies, neutral $B$ meson mixing, rare b decays, hadronic decays and CP…

I report on recent studies of hadronic physics performed by the BaBar Collaboration. Emphasis is given to the measurement of the properties of newly discovered charmed hadrons and to the searches for light and heavy pentaquarks.

I review a few selected topics concerning heavy-quark fragmentation, taking particular care about bottom- and charm-quark production in $e^+e^-$ annihilation and the inclusion of non-perturbative corrections. In particular, I discuss recent…

We present studies from the LHCb experiment of decays of the type H_b to H_c X, where H_b represents a beauty hadron (B+, B0 or Lambda_b) and H_c a charmed hadron (D0, D(*)+, Ds or Lambda_c). Such decays are important for the determination…

Data from HERA, LEP and the Tevatron, as well as from low energy experiments are used to constrain the scale of possible electron-quark contact interactions. Different models are considered, including the most general one, in which all new…

Compact analytic expressions have been obtained for the first order perturbative QCD corrections to the inclusive spectra of the leptons in the semileptonic decays of polarised heavy quarks. Charmed and beautiful $\Lambda$ baryons from…

The hard scatter from initial state hadrons to final state partons at LHC is reviewed with 2010 integrated luminosity. Plots showing certain quantities are shown as well as the powerful software tools for describing expectations.

We review some aspects of weak decays of hadrons containing one heavy quark. The main emphasis is on $B$ physics, in particular in the framework of the Heavy Quark Effective Theory.

Recent results in the field of b and c hadron spectroscopy at the LHCb experiment are presented. The analyses use the data collected with the LHCb detector in proton-proton collisions corresponding to an integrated luminosity up to 3.0…

The main physics topics of interest at LEP2, the CERN electron-positron collider with center-of-mass energy in the range (161-192) GeV, are reviewed. Progresses in both the precision tests of the standard model and the field of discovery…

We discuss few selected topics related to the calculation of hadronic amplitudes relevant for two-body non-leptonic B decays.

Hadronic interactions of two quasi-real photons have been studied extensively both during the LEP1 and the LEP2 data taking periods. The higher energies available at LEP2 in particular opened regions of phase space where hadronic processes…
