چکیده
In a recent article, W.-S. Hou and G.-G. Wong [Phys. Rev. D 67, 034003 (2003)] have investigated the spectrum of two-gluon glueballs below 3 GeV in a potential model with a dynamical gluon mass. We point out that, among the 18 states calculated by the authors, only three are physical. The other states either are spurious or possess a finite mass only due to an arbitrary restriction of the variational parameter.

We clarify the nonperturbative origin of the δ-function singularity at x = 0 in the chiral-odd twist-3 distribution function e(x) of the nucleon. We also compare a theoretical prediction for e(x) based on the chiral quark soliton model with the empirical information extracted from the CLAS semi-inclusive DIS measurement.

We study the zero-point energy of a massless scalar field subject to spheroidal boundary conditions. Using the zeta-function method, the zero-point energy is evaluated for small ellipticity. Axially symmetric vector fields are also considered. The results are interpreted within the context of QCD flux tubes and the MIT bag model.
