Pion interferometry is the unique tool to study the space-time evolution of the systems created in the ultrarelativistic nuclear collisions. Five different data sets have been analyzed in terms of cylindrical coordinates, and all yield consistent results. We conclude that the system expands longitudinally, the decoupling proper time is not, vert, similar5 fm/c, the duration of particle emission is very short <2 fm/c, and the transverse decoupling size is 1.5 to 2 times larger than the one cor...Pion interferometry is the unique tool to study the space-time evolution of the systems created in the ultrarelativistic nuclear collisions.

We conclude that the system expands longitudinally, the decoupling proper time is not, vert, similar5 fm/c, the duration of particle emission is very short <2 fm/c, and the transverse decoupling size is 1.5 to 2 times larger than the one corresponding to the collision geometry. That gives a causally consistent space-time evolution picture.» weiterlesen» einklappen
