RHIC Collision Data Provides New Evidence for the Existence of the "Baryon Bridge"
August 18 news, an international team of physicists, by analyzing nuclear collision data from the STAR detector at the Relativistic Heavy Ion Collider (RHIC), has presented strong evidence that baryon number may not be carried directly by quarks, but rather transmitted by a baryon bridge formed by gluons inside protons. The related paper has been published in the journal Science. Valerie A. Lentz, Brookhaven National Laboratory Baryons, including protons and neutrons, are generally considered to be composed of three quarks. In the existing understanding, the baryon number is viewed as being uniformly distributed among the three quarks. Meanwhile, gluons also exist inside protons; they are the carriers of the strong interaction. According to the description of quantum chromodynamics, gluons may form a Y-shaped structure known as a "baryon junction" or "gluon bridge" within the proton, but this structure has long lacked direct experimental evidence.

Module 4 of Steel Liner for Unit 3 of San'ao Nuclear Power Plant Successfully Hoisted
At 8:16 a.m. on August 15, the hoisting operation of Module 4 of the 3BRX steel liner for Unit 3 of the San'ao Nuclear Power Plant was officially launched. Under the stable operation of the 2,000-ton crawler crane of CNNC Machinery Engineering, the module successively completed a series of procedures including slewing, load-bearing travel, and alignment adjustment. After 220 minutes, the hoisting task was successfully completed. Module 4 of Unit 3 hoisted this time was integrally assembled from the fourth and fifth layers of the cylinder, with a diameter of approximately 45 meters and a height of 11.46 meters. The module features a large volume, susceptibility to deformation, and limited slewing space for the crane. The project team strictly implemented the special plan, completed site reinforcement, transport of baskets and counterweights, and crawler crane relocation in advance, organized hoisting simulation drills, and comprehensively inspected various safety hazards...
