In the case of the ChDR, a proof of principle study was carried out at the Cornell Electron Storage Ring (CESR) where beam profiles were measured in 2017 on a 5.3 GeV positron beam. …”

1744por Grigoryeva, Maria, Korchuganova, Tatiana, Padolski, Siarhei, Klimentov, Alexei, Titov, Mikhail“…Hundreds of petabytes of experimental data in high energy and nuclear physics (HENP) have already been obtained by unique scientific facilities, such as LHC, RHIC, KEK. As the accelerators are being modernized (energy and luminosity are increasing), data volumes are rapidly growing and have reached the exabyte scale, that also leads to an increasing the number of analysis and data processing tasks, that are competing continuously for computational resources. …”

A measurement of the $CP$ violation parameters sin(2β) and cos(2β) by a time-dependent Dalitz plot analysis of $B^0 \to D^{(*)}h^0$ decays with $D \to K^0_S \pi^+\pi^-$ decays is reported. …”
