On the Physics of a Cool Pion Gas
Robert D. Pisarski, Michel Tytgat
At finite temperature, the Nambu-Goldstone bosons of a spontaneously broken chiral symmetry travel at a velocity . This effect first appears at order in an expans…

Cool Pions move at less than the speed of light
Robert D. Pisarski, Michel Tytgat
At nonzero temperature, pions propagate through a thermal medium at less than the speed of light. About low temperature, this effect begins not at , but at next to leadin…

Triple Gauge Boson Couplings
G. Gounaris, J. -L. Kneur, D. Zeppenfeld +53
We present the results obtained by the "Triple Gauge Couplings" working group during the LEP2 Workshop (1994-1995). The report concentrates on the measurement of and co…
