Small Surface Oscillations of the Gluon Tube - the Elongated Bag

摘要

We investigate surface oscillations on a bag tube which is spanned out by a longitudinal color electric field inside it, and calculate the masses for such vibrations conceived of as quasi particles on the string being the bag tube for several suggestive values of the parameters in the bag model. Contrary to similar calculations by Vladimirsky we consider the case of there being a surface tension and we consider higher than zero angular momentum modes. The nonzero angular momentum modes have zero mass in the case of zero surface tension (when higher quantum corrections are ignored). Our considerations point towards the surface tension not being zero. (ERA citation 11:057575)
