“…The MTD modules are installed at a radius of about 403 cm, and cover about 45% in azimuth within |η| < 0.5. The timing resolution of the MTD is ∼100 ps and the spatial resolution is ∼1-2 cm in both r-φ and z directions [98].…”

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.

We have studied three realistic benchmark geometries for a new far detector GAZELLE to search for long-lived particles at the SuperKEKB accelerator in Tsukuba, Japan. The new detector would be housed in the same building as Belle II and observe the same e + e − collisions. To assess the discovery reach of GAZELLE, we have investigated three new physics models that predict long-lived particles: heavy neutral leptons produced in tau lepton decays, axion-like particles produced in B meson decays, and new scalars produced in association with a dark photon, as motivated by inelastic dark matter. We do not find significant gains in the new physics discovery reach of GAZELLE compared to the Belle II projections for the same final states. The main reasons are the practical limitations on the angular acceptance and size of GAZELLE, effectively making it at most comparable to Belle II, even though backgrounds in the far detector could be reduced to low rates. A far detector for long-lived particles would be well motivated in the case of a discovery by Belle II, since decays inside GAZELLE would facilitate studies of the decay products. Depending on the placement of GAZELLE, searches for light long-lived particles produced in the forward direction or signals of a confining hidden force could also benefit from such a far detector. Our general findings could help guide the design of far detectors at future electron-positron colliders such as the ILC, FCC-ee or CEPC.

“…The MTD modules are installed at a radius of about 403 cm, and the full MTD detector covers about 45% in azimuth within jηj < 0.5 [22]. The timing resolution of the MTD is ∼100 ps and the spatial resolutions are ∼1-2 cm in both rϕ and z directions as demonstrated in the cosmic-ray data [23]. The data used in this analysis were taken during the run in which the MTD detector was 63% completed.…”

We present measurements of the differential cross sections of inclusive J=ψ meson production as a function of transverse momentum (p J=ψ T) using the μ þ μ − and e þ e − decay channels in proton þ proton collisions at center-of-mass energies of 510 and 500 GeV, respectively, recorded by the STAR detector at the Relativistic Heavy Ion Collider. The measurement from the μ þ μ − channel is for 0 < p J=ψ T < 9 GeV=c and rapidity range jy J=ψ j < 0.4, and that from the e þ e − channel is for 4 < p J=ψ T < 20 GeV=c and jy J=ψ j < 1.0. The ψð2SÞ to J=ψ ratio is also measured for 4 < p meson T < 12 GeV=c through the e þ e − decay channel. Model calculations, which incorporate different approaches toward the J=ψ production mechanism, are compared with experimental results and show reasonable agreement within uncertainties.
