Available in PDF, EPUB and Kindle. Book excerpt: A search for charmless dihadron decays of neutral b-hadrons was performed using data obtained from 800 GeV/c proton-gold interactions. The following upper limits on the b-hadron branching ratios (including charge conjugates) were obtained at the 90% confidence limit: Br(Bs 2!K+K- ) + rs x Br(Bd 2![pi]+[pi]- )

This book was released on 2013 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work of thesis will investigate the heavy flavor sector, involving decays of particles containing the most massive quarks. In particular, we will study the bhadrons, that means particles containing b-quarks. The topic of this work is the measurements of B and CP asymmetries of two-body charmless decays of neutral b-hadrons, (B0 (s) → h+h' - and [Lambda]0 b →and ph -, where the h can be a pion or a kaon) collectively called B → h+h' -. Next sections describe the theoretical framework in which the b-hadrons are included. Firstly, it is necessary to introduce the CKM matrix describing the electroweak interactions between quarks and how the phenomenon of the CP violation manifests itself.

Book excerpt: We present CDF results on the branching fractions and time-integrated direct CP asymmetries for Bd, Bs and Lb decay modes into pairs of charmless charged hadrons (pions, kaons and protons). The data-set for these measurements amounts to 1fb−1 of p{bar p} collisions at a center of mass energy 1.96TeV. We report on the first observation of the Bs->Kpi, Lb-ppi and Lb->pK decay modes and on the measurement of their branching fractions and direct CP asymmetries.

Book excerpt: I report on recent measurements from the Belle and BABAR collaborations on the decay of the B meson to hadronic final states without a charm quark. The study of the branching fractions and angular distributions of B meson decays to hadronic final states without a charm quark probes the dynamics of both the weak and strong interactions, and plays an important role in understanding CP Violation (CPV) in the quark sector. CP Violation at the B factories is described graphically by a triangle with sides formed from the CKM matrix elements V{sub qd}V*{sub qb} (q = u, c, t) and internal angles [alpha], [beta] [gamma] (or [phi]2, [phi]1, [phi]3). Discrepancies in the measured values of the sides and angles could be an indication of New Physics beyond the Standard Model (SM) due to enhanced branching fractions or modified CP asymmetries. The experimental measurements of branching fractions, CP asymmetries, polarization and phases (both weak and strong) can be compared to theoretical models based on, for example, QCD factorization, SU(3) symmetry and Lattice QCD.

Book excerpt: Hybrid charmonium with mass (approximately) 4 GeV could be produced via a c{anti c} color-octet component in b --> c{anti c}s. These states could be narrow and could have a significant branching ratio to light hadrons, perhaps enhanced by glueballs. Decays to gluonic hadrons could make a sizable contribution to B --> no charm decays. Experimental signatures and search strategies are discussed.

Book excerpt: We present several searches for charmless hadronic two-body and three-body decays of B mesons from electron-positron annihilation data collected by the BABAR detector near the[Upsilon](4S) resonance. We report the preliminary branching fractions[Beta](B[sup 0][yields][pi][sup+][pi][sup -])= (4.1[+-] 1.0[+-] 0.7) x 10[sup -6], [Beta](B[sup 0][yields] K[sup+][pi][sup -])= (16.7[+-] 1.6[+-] 1.3) x 10[sup -6], [Beta](B[sup 0][yields][rho][sup -+][pi][sup -+])= (49[+-] 13[sub -5][sup+6]) x 10[sup -6], [Beta](B[sup+][yields][eta]' K[sup+])= (62[+-] 18[+-] 8) x 10[sup -6], and present upper limits for nine other decays.

Book excerpt: The authors review recent results on heavy quark physics focusing on Run II measurements of B hadron spectroscopy and decay at the Tevatron. A wealth of new B physics measurements from CDF and D0 has been available. These include the spectroscopy of excited B states (B**, B**{sub s}) and the observation of the [Sigma]{sub b} baryon. The discussion of the decays of B hadrons and measurements of branching fractions focuses on charmless two-body decays of B 2!hh−. They report several new B{sub s}° and [Lambda]{sub b}° decay channels.
