“…Since then, more statistics have been accumulated, the latest with the solenoidal tracker at RHIC (STAR) time-of-flight (TOF) detector [23,24] to extend particle identification capability to higher momentum particles. The analysis of this new data is ongoing.…”

The STAR Collaboration at the BNL Relativistic Heavy Ion Collider has measured two-pion correlation functions from p + p collisions at √ s = 200 GeV. Spatial scales are extracted via a femtoscopic analysis of the correlations, though this analysis is complicated by the presence of strong nonfemtoscopic effects. Our results are put into the context of the world data set of femtoscopy in hadron-hadron collisions. We present the first direct comparison of femtoscopy in p + p and heavy ion collisions, under identical analysis and detector conditions.

“…The time resolution of the VPD and barrel TOF can achieve ∼ 30 ps and < 80 ps, respectively, in heavy-ion collisions. With this performance, the TOF system allows π/K separation up to ∼1.6 GeV/c and (π, K)/p separation up to ∼3 GeV/c[94].…”

Antinuclei in heavy-ion collisions

We review progress in the study of antinuclei, starting from Dirac's equation and the discovery of the positron in cosmic-ray events. The development of proton accelerators led to the discovery of antiprotons, followed by the first antideuterons, demonstrating that antinucleons bind into antinuclei. With the development of heavy-ion programs at the Brookhaven AGS and CERN SPS, it was demonstrated that central collisions of heavy nuclei offer a fertile ground for research and discoveries in the area of antinuclei. In this review, we emphasize recent observations at Brookhaven's Relativistic Heavy Ion Collider and at CERN's Large Hadron Collider, namely, the antihypertriton and the antihelium-4, as well as measurements of the mass difference between light nuclei and antinuclei, and the interaction between antiprotons. Physics implications of the new observations and different production mechanisms are discussed. We also consider implications for related fields, such as hypernuclear physics and spacebased cosmic-ray experiments.

“…The time calibration is based on the determination of three components: a global offset, a channel-by-channel offset and a time slewing correction at the channel level. A large-area TOF system and muo1n telescope detector (MTD) based on MRPCs have been constructed and installed in the STAR experiment at RHIC [15,16]. The pure stop time resolution of the TOF sys- [17] after subtracting the start time jitter contribution in quadrature, and the MTD time resolution is observed to be ∼100 ps [18].…”

Purpose The end cap time of flight at Beijing Spectrometer is upgraded with multi-gap resistive plate chamber technology in order to improve the charged particle identification capability. The time-over-threshold is used for the time slewing correction instead of the signal amplitude. Methods The correlation of the multi-peak time-over-threshold and the hit position along the strip of the charged particle is investigated. Implementation of the off-line data calibration method is discussed in detail. Results and conclusion The overall time resolution for pions with momentum around 0.8 GeV/c is about 65 ps.
