نویسنده
چکیده
Groove chambers with different pitch and gap height have been tested. Gas amplifications of the order of a few times 10 have been obtained. Combining a groove structure with a GEM pre-amplification foil a gas gain of 10 was reached. The device is robust and can be produced at low cost in large sizes by a laser technique.

This paper presents results of elliptic flow measurements at moderate high transverse momentum in Au+Au collisions using the STAR detector at RHIC. Sizable v 2 is found up to 7 GeV/c in transverse momentum. Non-flow effects are discussed comparing correlations in p+p collisions and Au+Au collisions. v 2 from two-, four-and six-particle cumulant are shown and discussed.

I will present a review of the field of Hanbury Brown-Twiss interferometry in relativistic heavy-ion collisions. The “HBT puzzle” is explored in detail, emphasizing recent theoretical attempts to understand the persisting puzzle. I also present recent experimental results on azimuthally sensitive HBT, HBT of direct photons, and some surprises in the comparison of HBT results from p+p and Au+Au ...
