Book Description
The Tevatron experiments, CDF and D0, have produced a wealth of new B-physics results since the start of Run II in 2001. We've observed new B-hadrons, seen new effects, and increased many-fold the precision with which we know the properties of b-quark systems. In these proceedings, we will discuss two of the most fruitful areas in the Tevatron B-physics program: lifetimes and mixing. We'll examine the experimental issues driving these analyses, present a summary of the latest results, and discuss prospects for the future.

Book Description
The authors present recent results on b-hadron lifetimes and mixing obtained from the analysis of the data collected at the Tevatron Collider by the CDF and D0 Collaborations in the period 2002-2004. Many lifetime measurements have been updated since the Summer 2004 conferences, sometimes improving significantly the accuracy. Likewise the measurement of the B{sub d} oscillation frequency has been updated. New limits on the B{sub s} oscillation frequency have been determined using for the first time Run II data.

Book Description
We present the CDF results using 1.0 fb−1 of data on the mixing frequency measurement in the B°{sub s} system and the lifetime measurements of several B hadrons. We obtain [Delta]m{sub s} = 17.77 ± 0.1 ± 0.07 ps−1 and c[tau]([Lambda]{sub b}) = 473.8 ± 23.1 ±3.5 [mu]m. The later one is more than 3[sigma] above the world average, but in reasonable agreement with HQE calculations.

Book Description
This book offers the first strong evidence of the existence of CP violation in neutral B decays extracted from sophisticated B factories in the US and Japan. It also holds out the expectation of rare B decays and D, K physics in the near future. In addition, new physics beyond the Standard Model is described. Both experimental and theoretical points of view are given.

Book Description
Time-dependent B[sup 0][bar B][sup 0] flavor oscillations and B[sup 0] and B[sup+] lifetimes are studied in a sample of fully reconstructed B mesons collected with the BABAR detector, running at the PEP-II asymmetric e[sup+]e[sup -] B Factory with center-of-mass energies near the[Upsilon](4S) resonance. This is the first time that time-dependent mixing and lifetime measurements have been performed at[Upsilon](4S) energies.

Book Description
The Tevatron collider at Fermilab provides a very rich environment for the study of b-hadrons. Both the D0 and CDF experiments have collected a sample of about 1 fb{sup -1}. they report results on three topics: b-hadron lifetimes, polarization amplitudes and the decay width difference in B{sub s}{sup 0} {yields} J/{psi}{phi}, and B{sub s}{sup 0} mixing.

Book Description
This PhD thesis is dedicated to a subfield of elementary particle physics called “Flavour Physics”. The Standard Model of Particle Physics (SM) has been confirmed by thousands of experimental measurements with a high precision. But the SM leaves important questions open, like what is the nature of dark matter or what is the origin of the matter-antimatter asymmetry in the Universe. By comparing high precision Standard Model calculations with extremely precise measurements, one can find the first glimpses of the physics beyond the SM – currently we see the first hints of a potential breakdown of the SM in flavour observables. This can then be compared with purely theoretical considerations about new physics models, known as model building. Both precision calculations and model building are extremely specialised fields and this outstanding thesis contributes significantly to both topics within the field of Flavour Physics and sheds new light on the observed anomalies.
