G. Lambiase et Vv. Nesterenko, CRITICAL-TEMPERATURE IN THE NAMBU-GOTO STRING WITH MASSIVE ENDS, Physics letters. Section B, 398(3-4), 1997, pp. 335-341
In the one-string approximation, it is shown that the critical (or dec
onfinement) temperature for the Nambu-Goto string connecting the point
-like masses (quarks) does not depend on the value of these masses. Th
is temperature turns out to be the same as that in the case of string
with fixed ends (infinitely heavy immobile quarks). (C) 1997 Elsevier
