High-energy collision study reveals new insights into quark-gluon plasma

 



In high-energy physics, researchers have unveiled how high-energy partons lose energy in nucleus-nucleus collisions, an essential process in studying quark-gluon plasma (QGP). This finding could enhance our knowledge of the early universe moments after the Big Bang.

The study reveals that the jet transport coefficient over temperature cubed, a critical factor in parton energy loss in QGP, decreases with increasing medium temperature. This discovery, supported by a significant enhancement of the elliptic flow parameter (v2(pT)) for large transverse momentum (pT) hadrons, provides a more in-depth understanding of jet quenching in high-energy collisions.

High-energy collisions create a hot, dense state of matter known as the QGP. As partons pass through this medium, they lose energy. This process, known as jet quenching, leads to the suppression of high pT hadrons, measured by the nuclear modification factor (RAA(pT)), and the azimuthal anisotropy, measured by the v2(pT). The team used a next-to-leading-order perturbative QCD parton model to analyze data from the Relativistic Heavy-Ion Collider (RHIC) and the Large Hadron Collider (LHC). By fitting their models to the experimental data, they found that the jet transport coefficient's scaled value (q^/T3) decreases with temperature. This novel approach provides a more accurate description of how jets lose energy in these extreme conditions.

"This discovery helps us understand the behavior of partons in the quark-gluon plasma more accurately," says Prof. Han-Zhong Zhang, the corresponding author. "It shows that partons lose more energy near the critical temperature, which could explain the enhanced azimuthal anisotropy observed in high-energy collisions."

The findings suggest that as partons travel through the QGP, they lose more energy near the transition from QGP to the hadron phase, strengthening the azimuthal anisotropy by approximately 10% at RHIC and LHC. "In the future, we hope to refine our model and enrich the information on qˆ, allowing us to better describe RAA(pT) and v2(pT) simultaneously for both RHIC and LHC energies," Prof. Zhang says. This study advances high-energy nuclear physics, providing deeper insights into jet energy loss in high-energy collisions. These findings could enhance our understanding of the quark-gluon plasma and pave the way for future research into the fundamental properties of matter under extreme conditions. This research is a collaborative effort between South China Normal University and Central China Normal University.

Freezing light? Italian scientists froze fastest thing in universe, here’s how

In a rare occurrence, physics made it possible to control the fastest travelling element - light. Italian scientists have managed to freeze the light, as per reports. A recent study published in a British weekly journal reportedly revealed that light can exhibit ‘ supersolid behavior ’ a unique state of matter that flows without friction while retaining a solid-like structure. The research, led by Antonio Gianfate from CNR Nanotec and Davide Nigro from the University of Pavia, marks a significant step in understanding supersolidity in light. The scientists described their findings as “just the beginning” of this exploration, as per reports. In what can be termed as ‘manipulating photons under controlled quantum conditions ’, the scientists demonstrated that light, too, can exhibit this behaviour. (A photon is a bundle of electromagnetic energy which is massless, and travel at the speed of light) How did scientists freeze light? As we know, freezing involves lowering a liquid’s tempera...

Physicists observe a new form of magnetism for the first time

MIT physicists have demonstrated a new form of magnetism that could one day be harnessed to build faster, denser, and less power-hungry " spintronic " memory chips. The new magnetic state is a mash-up of two main forms of magnetism: the ferromagnetism of everyday fridge magnets and compass needles, and antiferromagnetism, in which materials have magnetic properties at the microscale yet are not macroscopically magnetized. Now, the MIT team has demonstrated a new form of magnetism , termed "p-wave magnetism." Physicists have long observed that electrons of atoms in regular ferromagnets share the same orientation of "spin," like so many tiny compasses pointing in the same direction. This spin alignment generates a magnetic field, which gives a ferromagnet its inherent magnetism. Electrons belonging to magnetic atoms in an antiferromagnet also have spin, although these spins alternate, with electrons orbiting neighboring atoms aligning their spins antiparalle...
