Results from pp at 62 . 4 and 200 GeV with the BRAHMS experiment
نویسنده
چکیده
Measurements of elementary pp collisions are essential for understanding heavy ion collisions. Results for pp collisions at 200 and 62.4 GeV are presented. At both energies NLO pQCD describes pion production well. The measured pion transverse single spin asymmetries are very large at 62.4 GeV and are reasonably well described by models relying on pQCD at transverse momenta larger than 1 GeV/c.

The rapidity dependence of the proton - to - pion ratio in Au + Au and p + p collisions at √ s NN = 62 . 4 and 200
The proton-to-pion yield ratios measured in the BRAHMS experiment for Au+Au and p+p collisions at √ s NN = 62.4 GeV and √ s NN = 200 GeV are presented as a function of transverse momentum and collision centrality within the pseudorapidity range 0 ≤ η ≤ 3.8. A strong pseu-dorapidity dependence of these ratios is observed. In Au+Au collisions at √ s NN = 200 GeV, η ≈ 2.2, and at √ s NN = 62.4 GeV...

The BRAHMS experiment at RHIC has measured the transverse single spin asymmetries in polarized pp induced pion production at RHIC. The results from the RHIC run-5 shows a significant asymmetry for π + and π − at moderate x F. The trend of the data is in agreement with lower energy results while the absolute values are surprisingly large. The p T dependence is approximately inversely propotional...
متن کاملRecent Results from the BRAHMS Experiment
We present recent results obtained by the BRAHMS experiment at the Relativistic Heavy Ion Collider (RHIC) for the systems of Au + Au and Cu + Cu at √ s N N = 200 GeV and at 62.4 GeV, and p + p at √ s N N = 200 GeV. BRAHMS explores reaction dynamics and properties of the hot and high energy density matter produced in ultra-relativistic heavy-ion collisions versus its longitudinal expansion. Over...

Elliptic flow has been measured by the BRAHMS experiment as a function of transverse momentum and pseudorapidity for the Au+Au reaction at √ s N N = 200 GeV. Identified-particle v 2 (η, p t) values were obtained with the two BRAHMS spectrometers at pseudorapidities η ≈ 0, 1, and 3.4. The results show that the differential v 2 (η, p t) values for a given particle type are essentially constant ov...
متن کاملParticle production at RHIC energies
This paper presents recent results from the BRAHMS experiment at RHIC; including results on particle production in rapidity space extending from y=0 to y ∼ 3 and on the transverse momentum distribution of fully identified charged particles. These results were obtained from the 5% most central Au-Au collisions recorded during RHIC Run-2 at √ sNN = 200 GeV.
