eta - eta' - glueball mixing

, 2010
We have revisited glueball mixing with the pseudoscalar mesons in the MIT bag model scheme. The calculation has been performed in the spherical cavity approximation to the bag using two different fermion propagators, the cavity and the free propagators. We obtain a very small probability of mixing for the eta at the level of $0.04-0.1% and a bigger for

3DCryoHolder: a new open access 3D printable system to store and transport silicon nitride membranes under cryogenic conditions for spectromicroscopy at low temperature

Journal of Synchrotron Radiation
Data acquisition under cryogenic conditions allows one to avoid unwanted damage caused by beam irradiation. This is particularly important for the study of biological samples at hard X-ray, micro- or nano-probe beamlines, which focus synchrotron ...

Transient growth in Taylor-Couette flow [PDF]

, 2002
Transient growth due to non-normality is investigated for the Taylor-Couette problem with counter-rotating cylinders as a function of aspect ratio eta and Reynolds number Re. For all Re < 500, transient growth is enhanced by curvature, i.e.

Modification of Kawai model about the mixing of the pseudoscalar mesons [PDF]

, 2000
The Kawai model describing the glueball-quarkonia mixing is modified. The mixing of $\eta$, $\eta^\prime$ and $\eta(1410)$ is re-investigated based on the modified Kawai model.
