The application of our glueball-qq̄ filter to the centrally produced KK̄π system shows that the f1(1285) and f1(1420) have the same behaviour; namely consistent with the f1(1420) being the partner to the f1(1285) in the P1 nonet of axial mesons. We determine a flavour singlet-octet mixing angle of ∼ 50 for this nonet and highlight that the existence of the supposed f1(1510) needs confirmation. e-...

A common hydrodynamic feature in industrial scale circulating fluidized beds is the presence of clusters. The continuous formation and destruction of clusters strongly influences particle hold-up, pressure drop, heat transfer at the wall, and mixing. In this paper fiber optic data is analyzed using discrete wavelet analysis to characterize the dynamic behavior of clusters. Five radial positions...

A dynamical valence and sea quark mixing model is shown to fit the baryon ground state properties as well as the spin content of the nucleon. The relativistic correction and the q3↔q3qq̄ transition terms induced by the quark axial vector current ψ̄~γγ5ψ in this model space is responsible for the quark spin reduction. 14.20.Dh, 12.39.Jh, 12.39.Pn, 24.85.+p Typeset using REVTEX

We present quenched results for B meson decay constants using NRQCD b quarks and O(a) tadpole improved clover light quarks. For the first time, one-loop matching factors between lattice and continuum currents are incorporated through O(α/M) taking operator mixing fully into account. This includes an important O(α a) discretization correction to the heavy-light axial vector current. We find f B ...

The renormalized contribution of fermions to the curvature masses vector and axial-vector mesons is derived with two different methods at leading order in loop expansion applied (2+1)-flavor constituent quark-meson model. corresponding scalar pseudoscalar mesons, already known literature, rederived a transparent way. temperature dependence mass various (axial-)vector modes obtained by decomposi...

In many microreactors, reactant flows are split into many lamination segments and then fed into the reactor to enhance mixing efficiency. This feeding method is applied since mixing in microreactors is mainly driven by diffusion because of low Reynolds and thus the mixing time is proportional to the square of diffusion length. The mixing efficiency of reactants greatly influences the product co...

The QCD sum rule for the correlator of topological charge densities χ(Q2) and related to it longitudinal part of the correlator of singlet axial currents is considered in the framework of instanton model. The coupling constant fη′ of η -meson with the singlet axial current is determined. Its value appears to be in a good coincidence with the value determined recently from the connection of the ...
