After 25 Years, the Muon Wobble Puzzle Sees Key New Progress in Physics

For 25 years, precise measurements of how muons wobble in a magnetic field have been a major puzzle in particle physics. Early experiments showed a discrepancy between the measured value of the muon's g-factor and theoretical predictions, a difference once seen as a possible hint of unknown particles. Recent new theoretical calculations and experimental analyses have brought a new twist to this puzzle. The muon is a heavier cousin of the electron that precesses like a tiny magnet in a magnetic field. Its extra wobble is quantified by the muon g-2 coefficient. According to quantum theory, known particles and interactions influence this coefficient through fleeting quantum fluctuations, making muon g-2 a key test of the Standard Model...

Large Structure for CMS Future High-Granularity Calorimeter Passes Rigorous Cold Tests

A key engineering test for the future High-Granularity Calorimeter (HGCAL) of the CMS experiment at CERN has recently made progress. One of the largest HGCAL structures has completed a series of rigorous cold tests, during which no overheating, condensation, or leakage was recorded on the outer panels, laying the groundwork for its future service at the High-Luminosity Large Hadron Collider (HL-LHC). HGCAL will replace the existing endcap calorimeters of the CMS experiment to reconstruct particle showers with greater precision under HL-LHC operating conditions. The structure tested this time is the first of two large stainless steel absorber structures. By design, the active elements of HGCAL will be installed within the absorber structures and must maintain long-term stable performance in a cryogenic environment...

Japanese Poll: 76% of Respondents Support Maintaining the "Three Non-Nuclear Principles"

The Tokyo Shimbun, citing a national poll conducted by the Kyodo News-affiliated survey organization from June to July among 3,000 people aged 18 and above, reported that 76% of Japanese support maintaining the Three Non-Nuclear Principles of not manufacturing, not possessing, and not allowing the introduction of nuclear weapons; 77% oppose nuclear-sharing arrangements (i.e., the U.S. stationing nuclear weapons in Japan and operating them jointly). Given that Japan is the only country to have suffered atomic bombing in war, the results highlight strong anti-nuclear sentiment, while debate over whether to revise the principles is intensifying. Support for Japan joining the Treaty on the Prohibition of Nuclear Weapons before the first review conference in November stands at 55%, down 5 percentage points from the previous year; opponents account for 42%, of whom 56% believe that joining would not lead to nuclear disarmament. Regarding recent U.S. actions...
