The collective description of the octupole degrees of freedom has been a long standing problem in nuclear physics @1#. The phenomenological description of low-energy vibrational states @2,3# discussed them in terms of simple ‘‘surface modes’’ thus allowing for the description of the octupole degrees of freedom in terms of seven collective variables a3m @2,4#. In the 1980s, theoretical calculati...

Possibility to detect DCC fluctuations is discussed. It is shown that interactions with quark background and dissipative effects due to interactions in the chiral field may result in damping of fluctuations. Since the magnitude of fluctuations depends strongly on the initial state and speed of chiral phase transition accurate evaluation of all modifying processes is required to predict observab...
