New results going beyond those obtained from isospin and flavor symmetry and subject to clear experimental tests are obtained for effects of FSI in B decays to final states containing neutral flavor-mixed mesons like ω, φ, η and η. The most general strong-interaction diagrams containing arbitrary numbers of quarks and gluons are included with the assumptions that any qq̄ pair created by gluons m...

ΛQCD/mb) and obtain the relevant operators to order λ in SCETI. These operators are constructed with or without spectator quarks including the four-quark operators contributing to annihilation and W -exchange channels. And we employ SCETII where the small parameter becomes of order ΛQCD/mb, and evolve the operators in order to compute the decay amplitudes for rare radiative decays in soft-colli...

An analysis of semileptonic decays of B mesons with the emission of a single soft pion is presented in the framework of the heavy-quark limit using an effective Lagrangian which implements chiral and heavy-quark symmetries. The analysis is performed at leading order of the chiral and inverse heavy mass expansions. In addition to the ground state heavy mesons some of their resonances are include...

We address the nonperturbative effects associated with soft charm quarks in inclusive B decays. Such corrections are allowed by the OPE, but have largely escaped attention so far. The related four-quark ‘double heavy’ expectation values of the form 〈B|b̄c c̄b|B〉 are computed in the 1/mc expansion by integrating out the charm field to one and two loops. A significant enhancement of the two-loop co...

A careful investigation of 1/mb power suppressed effects is crucial for enhancing predictive power of the QCD factorization approach to charmless B decays. It is instructive to systematically investigate the 1/mb effects from soft and hard gluon exchanges, in addition to annihilation topology in the charmless B decays. In this work we try to give a systematic discussion on impact of such soft a...

BACKGROUND The aim of this study was to verify the intra-individual reproducibility of natural head position (NHP) in centric relation (CR) position, to prove the inter-individual differences in the Frankfort horizontal plane and sella-nasion line compared with the true horizontal line, and to establish linear norms from A-point, B-point, Pog as well as soft tissue A-point, soft tissue B-point,...

OBJECTIVE The aim of this animal study was to evaluate the possible effects of Carbonated Soft Drink consumption on the rate of orthodontic tooth movement in rats. MATERIALS AND METHODS Thirty-six adult male Sprague-Dawley rats were randomly divided into two experimental groups and one control group. In the experimental groups (A&B), the water in the dietary regimen was replaced with soft dri...

PURPOSE The aim of this study was to compare the mandibular hard and soft tissue measurements of unilateral and bilateral cleft lip and palate patients with non-cleft individuals. MATERIALS AND METHODS The study sample comprised of lateral cephalograms of 45 subjects. Sample included 15 non-cleft (NC), 15 unilateral cleft lip and palate (UCLP) and 15 bilateral cleft lip and palate (BCLP) case...
