MIT and CERN recreated early-universe conditions by colliding lead ions at near-light speed in the LHC, tracing how quarks slow and generate a wake in quark-gluon plasma, providing definitive evidence that this primordial soup behaves like a liquid rather than a gas, with implications for understanding the birth of matter.
Physicists at CERN’s Large Hadron Collider (CMS collaboration) detected a subtle dip (less than 1%) in backward particle production as a high-energy quark moved through a tiny droplet of quark-gluon plasma, revealing a wake formed by energy transfer to the primordial fluid. By using Z bosons as clean markers, researchers could isolate this effect and gain a lab-side glimpse into the hot, liquid-like plasma that filled the early universe microseconds after the Big Bang.
Physicists analyzing LHC data from CERN used Z bosons as markers to track quarks moving through quark-gluon plasma, confirming that this primordial soup behaves like a liquid and creates wake patterns as it’s disturbed, a finding that supports long-standing theories about the early universe and provides new ways to study the properties of this exotic fluid.
The Large Hadron Collider (LHC) in Switzerland will be shut down starting June for about five years to undergo major upgrades to increase its collision capacity, with the goal of enabling more advanced experiments. During this period, CERN is also planning the development of the Future Circular Collider, a much larger and more powerful accelerator, although its future is uncertain due to high costs and scientific debates. The LHC's shutdown is part of ongoing efforts to deepen our understanding of fundamental physics, including the universe's origins.
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.
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 LHCb experiment at the LHC has achieved a highly precise measurement of the Z boson mass, finding it to be approximately 91.184 GeV with an uncertainty of 9.5 MeV, aligning with previous measurements and the Standard Model prediction, paving the way for future high-precision studies at the LHC and beyond.
Researchers at the Max Planck Institute have announced new findings on the Higgs boson, enhancing our understanding of its interactions with W and Z bosons, which are crucial to the Standard Model of particle physics.

A recent experiment at CERN's Large Hadron Collider observed an unexpectedly frequent ultra-rare decay of kaons, challenging the predictions of the standard model of physics. The NA62 experiment detected this decay 13 times out of 100 billion kaons, suggesting potential flaws in the current model. While further data and replication are needed, this finding could significantly impact our understanding of particle physics.
The ATLAS collaboration at CERN's Large Hadron Collider has observed top quarks in collisions between lead ions for the first time, marking a significant step in understanding the early universe's conditions. This discovery allows scientists to study the quark-gluon plasma, a state of matter present just after the Big Bang, and use top quarks as time markers to probe its evolution. The findings also open avenues for exploring momentum distribution within atomic nuclei and further understanding fundamental forces.
