ALICE Detects Gluon Saturation Clues Inside Nuclei

CERN’s ALICE experiment used incoherent J/ψ photonuclear production to probe local gluon density fluctuations inside lead nuclei, scanning with momentum transfer to resolutions from 0.6 to 0.2 femtometers. The data show a suppression of J/ψ production at the smallest scales with about 3-sigma significance, challenging traditional nuclear shadowing and aligning with the gluon-saturation picture predicted by quantum chromodynamics, revealing densely packed gluon states inside nuclei.

Ted Lasso Welcomes a Fresh Coach as Season 4 Introduces Alice

THR reports English actress Tanya Reynolds joins Apple TV+'s Ted Lasso as Alice, AFC Richmond’s assistant coach for the new women’s team in Season 4. Reynolds, who hadn’t seen the show before, landed the role after a Zoom with Jason Sudeikis and binge-watching the first three seasons to prepare. Her character, once brittle but deeply human, navigates finding her coaching voice as the series shifts focus to the women’s team, with the main cast returning; Season 4 drops Aug. 5 on Apple TV+ with weekly episodes.

ALICE Discovers Antimatter Counterpart of Hyperhelium-4

The ALICE collaboration at the Large Hadron Collider has found the first evidence of antihyperhelium-4, the heaviest antimatter hypernucleus observed at the LHC, with a significance of 3.5 standard deviations. This discovery, based on 2018 lead-lead collision data, supports the statistical hadronisation model's predictions and contributes to understanding the matter-antimatter asymmetry in the universe. The findings also include evidence of antihyperhydrogen-4 and confirm equal production of matter and antimatter at LHC energies.

Insights into Charm and Beauty Particles in Quark-Gluon Plasma Revealed by ALICE Measurements

The ALICE collaboration at CERN has conducted new measurements on the dynamics of charm and beauty particles in quark-gluon plasma. By analyzing non-head-on lead-lead collisions, they compared the elliptic flow of prompt D mesons (produced right after the collisions) with that of non-prompt D mesons (produced later in the decays of B mesons). The results show that the elliptic flow of non-prompt D mesons is weaker than that of prompt D mesons, confirming expectations and shedding light on the thermalization of beauty quarks. These findings pave the way for further measurements in the future.
