Particle

• Researchers at CERN’s Large Hadron Collider have detected anomalous behavior in "penguin decays," which are incredibly rare particle transformations. • The observed results deviate from the theoretical predictions of the Standard Model, the foundational theory explaining the universe's fundamental particles and forces. • This discovery is significant because it provides some of the strongest evidence yet for "new physics," suggesting the existence of previously unknown particles or forces.

• Astronomers have traced a high-energy "ghost particle," known as a neutrino, back to a star-forming galaxy dubbed "Shadow Blaster." • The neutrino traveled for billions of years from a source located 11 billion light-years away, originating when the universe was only 3 billion years old. • This discovery is significant because Shadow Blaster would be the first individual dusty star-forming galaxy ever directly linked to a high-energy neutrino event.

• Researchers at CERN's Large Hadron Collider detected rare Higgs boson decay patterns that deviate from Standard Model predictions, suggesting potential physics beyond current theoretical frameworks. • The analysis examined 150 billion particle collisions collected over two years, revealing a 3.2 sigma deviation in the boson's decay pathways, announced on April 20 by the ATLAS and CMS collaborations. • The findings could indicate undiscovered particles or fundamental forces and represent significant progress toward understanding the universe's most elusive particles.
