The High Level Trigger and Express Data Production at STAR
Wayne Betts, Jinhui Chen, Yuri Fisyak +20
To meet the demands of the Beam Energy Scan phase-II (BES-II) program, the STAR experiment at RHIC developed a dual real-time framework consisting of a High Level Trigger (HLT) and…
Optimization and Performance Characterization of the Second Generation Fermilab Constant Fraction Discriminator Readout ASIC
Artur Apresyan, Shuoxing Wu, Si Xie +5
We present the optimization and performance characterization of the second-generation Fermilab Constant Fraction Discriminator ASIC (FCFD), designed for the readout of AC-coupled l…
Practical Considerations for Measuring Global Spin Density Matrix Elements of Vector Mesons in Heavy-Ion Collisions
Gavin Wilks, Xu Sun, Zhenyu Ye
The STAR Collaboration has reported a significant -meson global spin alignment () signal in Au+Au collisions at GeV by measuring the polar angle di…
Exploring the interplay of helicity and global-frame spin density matrix elements
Gavin Wilks, Zhenyu Ye
A significant -meson global spin alignment () signal was measured in Au+Au collisions at GeV. Conventional physics mechanisms such as …
