Quantum Drama: A Century of Debate Beyond Copenhagen

2025-03-29

Quantum Drama, a new book by Jim Baggott and John L Heilbron, offers a comprehensive look at the century-long history of quantum mechanics, going beyond the typical focus on the 1927 Solvay Conference. It delves into the ongoing debate surrounding interpretations of quantum mechanics, highlighting the experimental work of Aspect, Clauser, and Zeilinger on Bell's inequalities and the theoretical contributions of Zurek, Joos, and others on entanglement and decoherence. While accessible to a broad audience, some technical details might be more readily grasped by professional physicists. The book's timely release coincides with the centenary of quantum physics, providing a fresh perspective on this enduring scientific puzzle.

LHC Ultraperipheral Collisions Unravel the Mystery of Gluon Saturation

2025-02-11

Ultraperipheral collisions (UPCs) at the Large Hadron Collider (LHC) offer a unique window into gluon dynamics. Experiments use photons to probe gluons within protons and nuclei, investigating gluon saturation—a dynamic equilibrium between gluon splitting and recombination. Researchers found that as energy decreases, the number of gluons in hadrons increases, forming 'gluonic hotspots' that overlap in the gluon saturation regime. The experiments also observed nuclear shadowing, where nuclei contain fewer gluons than expected. These findings shed light on the origin of 99% of the visible universe's mass and the nature of the strong interaction. Future LHC runs and the Electron-Ion Collider (EIC) will further explore gluon dynamics, uncovering more mysteries.

LHC Unveils 23 Exotic Hadrons, Challenging Strong Interaction Theories

2024-12-20

The Large Hadron Collider (LHC) has yielded a surprising discovery: 23 exotic hadrons, including pentaquarks and tetraquarks, whose structures defy explanation by current theories. This discovery, akin to a fascinating detective story, is driving theorists to develop new models, such as hadronic molecule models and compact tetraquark models. Future experiments at the High-Luminosity LHC, Belle II, and BESIII will provide more data, offering further clues to unraveling the mysteries of the strong interaction.
