Separating the mixture of the K-1(1270) and K-1(1400) states, the B -> K-1(1270, 1400)nu(nu) over bar transition form factors are calculated in the three-point QCD sum rule approach. The longitudinal, transverse and total decay widths as well as the asymmetry parameter, characterizing the polarization of the axial K-1(1270, 1400) and the branching ratio for these decays, are evaluated.

ELECTROMAGNETIC FORM-FACTOR OF D-ASTERISK-]D TRANSITION IN THE TIME-LIKE REGION Alıyev, Tahmasıb; PAK, NK; REKALO, MP (Springer Science and Business Media LLC, 1994-12-01) The internal conversion process D* --> De(+) e(-), and D*($) over bar D-pair production in e(+) e(-) -collisions, e(+) e(-) --> D*($) over bar D, which are described by the same electromagnetic form factor with time-like momentum transfer, have been analyzed. After carrying out a general analysis of the kinematical aspects of the one-photon mechanism has been performed and the predictions of the vector-dominance model for the D* --> D transition form factor are discussed. It is shown that use of the asympto...
Form factors of D-s(+) -> phi(l)over-bar nu decay in QCD light cone sum rule Alıyev, Tahmasıb; Özpineci, Altuğ; Savcı, Mustafa (Springer Science and Business Media LLC, 2004-12-01) We calculate the form factors V, A(1), A(2) and A(0) appearing in the D-s --> phi transition by the light cone QCD sum rule method. We compare our results on these form factors with the current experimental results and existing theoretical calculations.
Form factor for penguin-induced B -> eta transition in light cone QCD sum rule Alıyev, Tahmasıb; Savcı, Mustafa (Springer Science and Business Media LLC, 2003-08-01) We calculate the penguin-induced form factor for the B --> etal(+)l(-) decay. This form factor is calculated by light cone QCD sum rules, including contributions from wave functions up to twist-4 as well as mass corrections of the light eta meson.
Measurement of the differential cross section and charge asymmetry for inclusive pp -> W-+/- + X production at root s=8 TeV Khachatryan, V. y; et. al. (Springer Science and Business Media LLC, 2016-08-01) The differential cross section and charge asymmetry for inclusive pp -> W-+/- + X -> mu(+/-)nu + X production at root s = 8 TeV are measured as a function of muon pseudorapidity. The data sample corresponds to an integrated luminosity of 18.8 fb(-1) recorded with the CMS detector at the LHC. These results provide important constraints on the parton distribution functions of the proton in the range of the Bjorken scaling variable x from 10(-3) to 10(-1).
Jet and underlying event properties as a function of charged-particle multiplicity in proton-proton collisions at root s=7 TeV Chatrchyan, S.; et. al. (Springer Science and Business Media LLC, 2013-12-01) Characteristics of multi-particle production in proton-proton collisions at root s = 7 TeV are studied as a function of the charged-particle multiplicity, N (ch). The produced particles are separated into two classes: those belonging to jets and those belonging to the underlying event. Charged particles are measured with pseudorapidity |eta| 0.25 GeV/c. Jets are reconstructed from charged-particles only and required to have p (T)> 5 GeV/c. The distributions of jet p (T), average p (T) of charged particles b...
