The authors present a search for the flavor-changing neutral current decay B{sub s}° →???− using about 0.45 fb−1 of data collected in p{bar p} collisions at √s = 1.96 TeV with the D0 detector at the Fermilab Tevatron Collider. They find an upper limit on the branching ratio of this decay normalized to B{sub s}° → J/?? of?(B{sub s}° →??+?−)/?(B{sub s}° → J/??)

The authors search for b → s??− transitions in B meson (B+, B°, or B{sub s}°) decays with 924 pb−1 of p{bar p} collisions at √s = 1.96 TeV collected with the CDF II detector at the Fermilab Tevatron. They find excesses with significances of 4.5, 2.9, and 2.4 standard deviations in the B+ →?+?−K+, B° →?+?−K*(892)°, and B{sub s}° →?+?−? decay modes, respectively. Using B → J/?h (h - K+, K*(892)°,?) decays as normalization channels, they report branching fractions for the previously observed B+ and B° decays as normalization channels, they report branching fractions for the previously observed B+ and B° decays,?(B+ →?+?−K+) = (0.59 ± 0.15 ± 0.04) x 10−6, and?(B° →?+?−K*(892)°) = (0.81 ± 0.30 ± 0.10) x 10−6, where the first uncertainty is statistical, and the second is systematic. These measurements are consistent with the world average results, and are competitive with the best available measurements. They set an upper limit on the relative branching fraction?(B{sub s}°→?+?−?)/?(B{sub s}°→J/??)

This thesis focuses on searches for squarks with the ATLAS detector in "compressed" scenarios where the scalar top is very close in mass to the lightest supersymmetric particle. These models are theoretically appealing because the presence of a quasi-degenerate scalar top enhances the self-annihilation cross-section of the lightest supersymmetric particle, acting therefore as a regulator of the dark matter relic density. Two main analyses are presented: the first is a search for scalar tops decaying to charm quarks. The identification of jets originating from the charm quark is very challenging due to its short lifetime. The calibration of tools for charm-tagging has paved the way to measuring the decay of the Higgs boson to pairs of charm quarks. The second analysis presented is the development of a novel technique for reconstructing low momentum b-hadrons. This tool has enabled the ATLAS collaboration to explore topologies that were previously inaccessible.

The authors report on a search for B{sub s}{sup 0} {yields} {mu}{sup +}{mu}{sup -} and B{sub d}{sup 0} {yields} {mu}{sup +}{mu}{sup -} decays in p{bar p} collisions at {radical}s = 1.96 TeV using 171 pb{sup -1} and 240 pb{sup -1} of data collected respectively by the CDF and D0 experiments at the Fermilab Tevatron Collider. The decay rates of these rare processes are sensitive to contributions from physics beyond the Standard Model. The results from the two experiments are a combined branching fraction limit of {Beta}(B{sub s}{sup 0} {yields} {mu}{sup +}{mu}{sup -})

This book is dedicated to Lev Okun, who passed away in November 2015. He was a true pioneer in probing fundamental dynamics.The book has two objectives. First is to showcase Okun's impact for decades since 1963, when he published his remarkable book Weak Interaction of Elementary Particles. Second is to present the current progress of our scientific community in the studies of our Universe. New directions and possible future developments are discussed, often using the past as a guide. The authors mostly focus on CP asymmetries in the transitions of hadrons and leptons, but they also discuss their rare decays, and talk about axions and supersymmetry, and possible connections with dark matter, extra dimensions, baryogenesis and multiverse.This book is suitable for readers who know quantum mechanics and quantum field theories in general.
