Asymmetry Parameter of the K1(1270, 1400) by Analyzing the B → K1νν Transition Form Factors within QCD
نویسنده
چکیده
Separating the mixture of the K1(1270) and K1(1400) states, the B → K1(1270, 1400)νν transition form factors are calculated in the three-point QCD sum rules approach. The longitudinal, transverse and total decay widths as well as the asymmetry parameter, characterizing the polarization of the axial K1(1270, 1400) and the branching ratio for these decays are evaluated.

Forward-backward Asymmetry and Branching Ratio of B → K1l+l− Transition in Supersymmetric Models
The mass eigen states K1(1270) and K1(1400) are mixture of the strange members of two axial-vector SU(3) octet, P1(K A 1 ) and P1(K B 1 ). Taking into account this mixture, the forward-backward asymmetry and branching ratio of B → K1(1270, 1400) l+l− transitions are studied in the framework of different supersymmetric models. It is found that the results have considerable deviation from the sta...
متن کاملHadronic Charmed Meson Decays Involving Axial Vector Mesons
Cabibbo-allowed charmed meson decays into a pseudoscalar meson and an axial-vector meson are studied. The charm to axial-vector meson transition form factors are evaluated in the Isgur-Scora-Grinstein-Wise quark model. The dipole momentum dependence of the D → K transition form factor and the presence of a sizable long-distance W -exchange are the two key ingredients for understanding the data ...

The effect of weak annihilation and u-quark penguin contribution on the branching ratio B → K1γ at next-to-leading order of αs are calculated using LEET approach. It is shown that the value of LEET form factor remains the same in the range of unitarity triangle phase α favored by the Standard Model. CP-asymmetry for above mentioned decay has been calculated and its suppression due to the hard s...
متن کاملRadiative B decays to the axial K mesons at next - to - leading order
We calculate the branching ratios of B → K1γ at next-to-leading order (NLO) of αs where K1 is the orbitally excited axial vector meson. The NLO decay amplitude is divided into the vertex correction and the hard spectator interaction part. The one is proportional to the weak form factor of B → K1 transition while the other is a convolution between light-cone distribution amplitudes and hard scat...
