India’s six-decade partnership with CERN puts it at the center of the LHC upgrade and the global hunt for dark matter, with Indian labs contributing to magnet systems, cryogenics, detectors and high-performance computing that underpinned the Higgs boson discovery and will push physics beyond the Standard Model as CERN restarts after a $1.5B upgrade in 2030.
After 18 years of discoveries, CERN’s Large Hadron Collider enters Long Shutdown 3 to be upgraded into the High-Luminosity LHC (HiLumi LHC). The upgrade will boost luminosity by about ten times, enabling more detailed data on the Higgs boson and other subatomic phenomena. The renovation includes major overhauls to magnets and infrastructure, with a gradual restart beginning in 2028 and full operation by 2030, marking a new era in particle physics research.
The Large Hadron Collider at CERN has entered a four-year Long Shutdown 3 to upgrade into the High-Luminosity LHC, which will raise collision rates by about tenfold and enable roughly 380 million Higgs bosons over its lifetime. The upgrade, which involves replacing thousands of magnets and other components, aims to deliver a much larger data set to probe the Higgs, dark matter, and the early universe. Operations are slated to resume in 2030 and continue into the 2040s, after which a new, higher-energy accelerator may replace it.
A theoretical team proposes a previously unknown heavy particle that mixes with the Higgs boson to act as a conduit between visible matter and dark matter residing in a warped fifth dimension. This could help explain fermion masses and the dark-to-visible matter ratio, but the particle would be too heavy for current colliders; future machines or gravitational-wave observations might provide indirect evidence.
Physicists have created an experimental analog of false vacuum decay—the hypothetical process that could, in theory, trigger a bubble of lower-energy vacuum that expands at light speed and rewrites physics. Using controllable quantum systems (like ultracold atoms or quantum circuits), researchers mimic the field dynamics predicted by quantum field theory to study bubble nucleation and expansion, providing empirical insight into vacuum stability. While the real universe’s decay probability is vanishingly small on human timescales, these analog experiments help test theoretical predictions about the Higgs potential and electroweak vacuum, and guide future work toward higher-fidelity simulations with more qubits to sharpen constraints on cosmic stability.
The Large Hadron Collider (LHC) is being shut down temporarily for upgrades to increase its collision capacity, with a long-term plan to replace it with the even larger Future Circular Collider, aiming to continue groundbreaking discoveries in fundamental physics despite high costs and scientific debates.
Mark Thomson, a renowned physicist, takes over as Cern's director general and plans to shut down the LHC for upgrades to enhance its capabilities, while also preparing for the ambitious Future Circular Collider project to continue exploring fundamental questions about the universe.
A new study proposes that particle mass and fundamental forces could originate from the geometry of hidden extra dimensions, specifically through evolving seven-dimensional shapes called G₂-manifolds, potentially eliminating the need for the Higgs boson in explaining mass.
Physicists at Brown University and the LHC continue to explore the Higgs boson, focusing on its interactions, potential implications for the universe's fate, and future collider projects, highlighting its fundamental role in understanding the universe and advancing particle physics.
The ATLAS Collaboration at the LHC has found evidence of rare Higgs boson decays into muons and a Z boson with a photon, providing deeper insights into the Higgs properties and potential hints of physics beyond the Standard Model, using combined data from Run 2 and Run 3.
The article discusses the current state and future prospects of particle colliders for studying the Higgs boson, highlighting the potential of a cost-effective and faster option called LEP3, which would repurpose existing infrastructure to produce large numbers of Higgs particles for detailed study, as an alternative to more expensive and longer-term projects like the Future Circular Collider.
