The hunt for hot nuclear matter

In particle physics, a jet is a shower of collimated particles generated by a highly energetic quark or gluon. In a lead-lead collision, jets must traverse through quark gluon plasma, altering their energy, track and consistency.

Physicists discover new class of pentaquarks

Tomasz Skwarnicki, professor of physics in the College of Arts and Sciences at Syracuse University, has uncovered new information about a class of particles called pentaquarks. His findings could lead to a new understanding ...

CMS gets first result using largest-ever LHC data sample

Just under three months after the final proton–proton collisions from the Large Hadron Collider (LHC)'s second run (Run 2), the CMS collaboration has submitted its first paper based on the full LHC dataset collected in ...

Producing four top quarks at once to explore the unknown

For several decades, particle physicists have been trying to better understand nature at the smallest distances by colliding particles at the highest energies. While the Standard Model of particle physics has successfully ...

The Large Hadron Collider prepares for the future

The Large Hadron Collider (LHC) is stopping proton collisions for five days this week to undergo numerous tests. Accelerator specialists need to test the LHC when it is not in production mode and there are only several weeks ...

Within 10 years, a high-luminosity LHC at CERN

A new site opened on Friday, June 15, 2018, at the LHC, the Large Hadron Collider. Begun in 2011, this project aims to commission a high-luminosity LHC (HL-LHC) by 2026 that will increase the number of proton-proton collisions ...

Scientists studying nuclear spin make a surprising discovery

In proton-proton smashups, more neutrons scatter to the right than the left relative to the proton spin direction. That was the accepted wisdom, and scientists thought the pattern would hold even when the protons struck larger ...
