Evidence of Spin-Interference Effects in Exclusive Photoproduction in Ultraperipheral Heavy-Ion Collisions
The STAR Collaboration
We report the first evidence of spin interference in exclusive photoproduction in ultraperipheral heavy-ion collisions at STAR at ~GeV. In Au+…
Measurement of transverse polarization of and hyperons inside jets in collisions at GeV
STAR Collaboration, B. E. Aboona, J. Adam +363
A surprisingly large transverse polarization of hyperons in unpolarized hadron-nucleon/nucleus collisions has been observed for 50 years, and the origin of this polarization r…
Energy Independence of the Collins Asymmetry in Collisions
STAR Collaboration, B. E. Aboona, J. Adam +367
The STAR experiment reports new, high-precision measurements of the transverse single-spin asymmetries for within jets, namely the Collins asymmetries, from transversely…
Exploring Lorentz Invariance Violation from Ultra-high-energy Gamma Rays Observed by LHAASO
Zhen Cao, F. Aharonian, Q. An +268
Recently the LHAASO Collaboration published the detection of 12 ultra-high-energy gamma-ray sources above 100 TeV, with the highest energy photon reaching 1.4 PeV. The first detect…
An Ultrahigh-energy -ray Bubble Powered by a Super PeVatron
The LHAASO Collaboration, Z. Cao, F. Aharonian +277
We report the detection of a -ray bubble spanning at least 100 in ultra high energy (UHE) up to a few PeV in the direction of the star-forming region Cygnus X, imply…
Detection of two TeV gamma-ray outbursts from NGC 1275 by LHAASO
Zhen Cao, F. Aharonian, Axikegu +275
The Water Cherenkov Detector Array (WCDA) is one of the components of Large High Altitude Air Shower Observatory (LHAASO) and can monitor any sources over two-thirds of the sky for…
