چکیده
In light of the recent experimental results on decays B+ → fX(1300)K and B±(0) → J/ψK X (1430) from Belle, we study the B → P (V )S type decays, B±(0) → f0(1370)K and B±(0) → J/ψK 0 (1430), in comparison with the B → P (V )T type decays, B±(0) → f2(1270)K and B±(0) → J/ψK 2 (1430). We calculate the BRs for these decays by using the form factors obtained in the ISGW2 model [the improved version of the original Isgur-Scora-Grinstein-Wise (ISGW) model], as well as the ISGW model for comparison. The ratios of B(B → P (V )S)/B(B → P (V )T ) are also presented. ∗[email protected], http://phya.yonsei.ac.kr/ ̃cskim/ †[email protected]

Almost Periodic Sequences and Functions with given Values
We present a method for constructing almost periodic sequences and functions with values in a metric space. Applying this method, we find almost periodic sequences and functions with prescribed values. Especially, for any totally bounded countable set X in a metric space, it is proved the existence of an almost periodic sequence {ψk}k∈Z such that {ψk; k ∈ Z} = X and ψk = ψk+lq(k), l ∈ Z for all...

The small P wave compoment of B → J/ψK * measured by CLEO makes it practical to measure sin 2β using B 0 → J/ψK * 0 → J/ψK S π 0 , independent from B 0 → J/ψK S. Because these modes are color suppressed, new physics enhanced color dipole bsg coupling, as hinted from the persistent B s.l. and n C problems as well as the newly observed large semi-inclusive B → η ′ + X s decay, may have significan...
متن کاملA Study of Exclusive Nonleptonic Decays of B Mesons into Final States of Strange Mesons and 1s or 2s Charmonia
Bound states of heavy quarks can serve as a laboratory for inquiry into the behaviour of the fundamental strong and electroweak interactions. This thesis examines observations of B0, B0, and B± mesons produced in proton-antiproton collisions at centre-of-mass energies of √ s = 1.8 TeV. The B-meson decay products are recorded using the Collider Detector at Fermilab (CDF) located on the Tevatron ...
متن کاملArithmetic Properties of Periodic Maps
Abstract. Let ψ1, · · · , ψk be periodic maps from Z to a field of characteristic p (where p is zero or a prime). Assume that positive integers n1, · · · , nk not divisible by p are their periods respectively. We show that ψ1 + · · · + ψk = 0 if ψ1(x) + · · · + ψk(x) = 0 for |S| consecutive integers x where S = ⋃ k s=1 {0, 1/ns, · · · , (ns − 1)/ns}. We also present some new results on finite s...
متن کاملA viable mouse model of factor X deficiency provides evidence for maternal transfer of factor X
BACKGROUND Activated factor X (FXa) is a vitamin K-dependent serine protease that plays a pivotal role in blood coagulation by converting prothrombin to thrombin. There are no reports of humans with complete deficiency of FX, and knockout of murine F10 is embryonic or perinatal lethal. OBJECTIVE We sought to generate a viable mouse model of FX deficiency. METHODS We used a socket-targeting ...
