Title eta-eta ' mixing in the flavor basis and large N Type Journal Article
Year 2010 Publication Physics Letters B Abbreviated Journal Phys. Lett. B
Volume 688 Issue 4-5 Pages 314-318
Keywords Meson; Mixing
Abstract The mass matrix for eta-eta' is derived in the flavor basis at O(p(4)) of the chiral Lagrangian using the large N approximation. Under certain assumptions, the mixing angle phi = 41.4 degrees and the decay constants ratio f(K)/f(pi) = 1.15 are calculated in agreement with the data. It appears that the FKS scheme arises as a special limit of the chiral Lagrangian. Their mass matrix is obtained without the hypothesis on the mixing pattern of the decay constants.

Title Radiative open charm decay of the Y(3940), Z(3930), X(4160) resonances Type Journal Article
Year 2010 Publication European Physical Journal A Abbreviated Journal Eur. Phys. J. A
Volume 44 Issue 3 Pages 479-486
Keywords
Abstract We determine the radiative decay amplitudes for the decay into D* and (D) over bar gamma, or (D) over bar gamma(s)* and s. of some of the charmonium- like states classified as X, Y, Z resonances, plus some other hidden charm states which are dynamically generated from the interaction of vector mesons with charm. The mass distributions as a function of the (D) over bar gamma or (D) over bar (s)gamma. invariant mass show a peculiar behavior as a consequence of the D* (D) over bar gamma* nature of these states. The experimental search of these magnitudes can shed light on the nature of these states.

Title Dynamically generated resonances from the vector octet-baryon octet interaction Type Journal Article
Year 2010 Publication European Physical Journal A Abbreviated Journal Eur. Phys. J. A
Volume 44 Issue 3 Pages 445-454
Keywords
Abstract We study the interaction of vector mesons with the octet of stable baryons in the framework of the local hidden gauge formalism using a coupled-channels unitary approach. We examine the scattering amplitudes and their poles, which can be associated to known J(P) = 1/2(-), 3/2(-) baryon resonances, in some cases, or give predictions in other ones. The formalism employed produces doublets of degenerate J(P) = 1/2(-), 3/2(-) states, a pattern which is observed experimentally in several cases. The findings of this work should also be useful to guide present experimental programs searching for new resonances, in particular in the strange sector where the current information is very poor.

Title Dynamically generated resonances from the vector octet-baryon decuplet interaction Type Journal Article
Year 2010 Publication European Physical Journal A Abbreviated Journal Eur. Phys. J. A
Volume 44 Issue 3 Pages 431-443
Keywords
Abstract We study the interaction of the octet of vector mesons with the decuplet of baryons using Lagrangians of the hidden gauge theory for vector interactions. The unitary amplitudes in coupled channels develop poles that can be associated with some known baryonic resonances, while there are predictions for new ones at the energy frontier of the experimental research. The work offers guidelines on how to search for these resonances.

Title Present status and first results of the final focus beam line at the KEK Accelerator Test Facility Type Journal Article
Year 2010 Publication Physical Review Special Topics-Accelerators and Beams Abbreviated Journal Phys. Rev. Spec. Top.-Accel. Beams
Volume 13 Issue 4 Pages 042801 - 10pp
Keywords
Abstract ATF2 is a final-focus test beam line which aims to focus the low emittance beam from the ATF damping ring to a vertical size of about 37 nm and to demonstrate nanometer level beam stability. Several advanced beam diagnostics and feedback tools are used. In December 2008, construction and installation were completed and beam commissioning started, supported by an international team of Asian, European, and U. S. scientists. The present status and first results are described.
