CERN Scientists Detect Quark Vortices in Early Universe’s Quark-Gluon Plasma for the First Time

A Glimpse into the Primordial Cosmic Fluid: Scientists Recreate Quark Vortices from the Universe’s First Moments

According to НВ — Техно: On October 7 at 18:03, researchers at CERN announced a groundbreaking discovery using the Large Hadron Collider (LHC): for the first time, they have observed vortex-like patterns formed by quarks within the quark-gluon plasma that existed shortly after the Big Bang. This finding sheds light on the unique fluid-like properties of this plasma during the universe’s earliest microseconds.

To reveal these subtle quark vortices, the team employed an innovative technique centered on the detection of neutral Z bosons. Since Z bosons interact minimally with the surrounding plasma, they serve as reliable markers for tracing quark behavior. Led by physicists from the Massachusetts Institute of Technology, the international collaboration meticulously analyzed approximately 2,000 events out of 13 billion recorded collisions, successfully validating theoretical models of quark-gluon plasma dynamics.

Understanding the Quark-Gluon Plasma

During the universe’s first microseconds, temperatures soared to trillions of degrees, creating a quark-gluon plasma that existed just before protons and neutrons formed. This plasma was extraordinarily dense and behaved like a continuous liquid rather than isolated particles, significantly slowing down passing particles.

"The plasma is so dense that it noticeably slows particles, acting as a true fluid instead of a mere collection of separate elements." Professor Yen-Ji Lee

The data collected allows scientists to probe the plasma’s density, dissipation timescales, and particle interaction characteristics in unprecedented detail. These insights mark a crucial step toward comprehending the physics governing the very early universe and the fundamental nature of matter.

This milestone opens new avenues for exploring matter under extreme conditions similar to those just after the Big Bang. Improved understanding of quark-gluon plasma not only advances particle physics theories but also enriches knowledge of overarching physical laws shaping the cosmos. Such research has the potential to deepen our grasp of gravitational waves and other astrophysical phenomena, elevating their study within modern physics.

This discovery not only enhances our understanding of the quark-gluon plasma but also connects to other significant advancements in particle physics. For instance, researchers have recently successfully recreated cosmic particle showers in the LHC, providing further insights into the fundamental forces at play in the universe's early moments.
