We investigate f(0)-sigma mixing in the framework of light cone QCD sum rules and by employing the experimental results about the decay widths and the masses of these scalar mesons we estimate the scalar mixing angle by using sigma meson data and f(0) meson data. The two values we thus obtain of the scalar mixing angle are not entirely consistent with each other, possibly indicating that the structure of these mesons cannot be simple quark-antiquark states.

General analysis of polarization phenomena in inclusive and semi-inclusive radiative decays of B mesons Pak, Namık Kemal; Rekalo, MP; Yilmaz, T (IOP Publishing, 2000-07-01) Polarization characteristics of photons produced in inclusive and semi-inclusive radiative decays of B mesons, B --> gamma + X-s, B --> gamma + h + X', are described in a general model-independent framework, using the structure function formalism.
Strong coupling constants of decuplet baryons with vector mesons Alıyev, Tahmasıb; Savcı, Mustafa (American Physical Society (APS), 2010-11-10) We provide a comprehensive study of strong coupling constants of decuplet baryons with light nonet vector mesons in the framework of light cone QCD sum rules. Using the symmetry arguments, we argue that all coupling constants entering the calculations can be expressed in terms of only one invariant function even if the SU(3)(f) symmetry breaking effects are taken into account. We estimate the order of SU(3)(f) symmetry violations, which are automatically considered by the employed approach.
Measurements of differential production cross sections for a Z boson in association with jets in pp collisions at root s=8 TeV Khachatryan, V.; et. al. (Springer Science and Business Media LLC, 2017-04-01) Cross sections for the production of a Z boson in association with jets in proton-proton collisions at a centre-of-mass energy of root s = 8 TeV are measured using a data sample collected by the CMS experiment at the LHC corresponding to 19.6 fb(-1). Differential cross sections are presented as functions of up to three observables that describe the jet kinematics and the jet activity. Correlations between the azimuthal directions and the rapidities of the jets and the Z boson are studied in detail. The pred...
Investigations of spinodal dynamics in asymmetric nuclear matter within a stochastic relativistic model Yılmaz, Osman; ACAR, FERİDE PINAR; Saatci, S.; GÖKALP, AHMET (Springer Science and Business Media LLC, 2013-03-01) Early development of spinodal instabilities and density correlation functions in asymmetric nuclear matter are investigated in the stochastic extension of the Walecka-type relativistic mean field including coupling with rho meson. Calculations are performed under typical conditions encountered in heavy-ion collisions and in the crusts of neutron stars. In general, growth of instabilities occur relatively slower for increasing charge asymmetry of matter. At higher densities around rho = 0.4 rho(0) fluctuatio...
Measurement of inclusive and differential Higgs boson production cross sections in the diphoton decay channel in proton-proton collisions at root s=13 TeV Sirunyan, A. M.; et. al. (Springer Science and Business Media LLC, 2019-01-01) Measurements of the inclusive and differential production cross sections for the Higgs boson in the diphoton decay channel are performed using the data set of proton-proton collisions at 13 TeV collected by the CMS experiment at the LHC in 2016 and corresponding to an integrated luminosity of 35.9 fb(-1). The cross sections are measured in a fiducial phase space defined by a set of requirements on the isolation and kinematic variables of the photons. Differential cross sections are measured as functions of ...
