ALICE experiment announces first results from LHC’s lead-ion collisions

In the first measurement, scientists counted the charged particles that were produced from a few thousand of the most central lead-ion collisions—those where the lead nuclei hit each other head-on. The result showed that about 18,000 particles are produced from collisions of lead ions, which is about 2.2 times more particles than produced in similar…… Continue reading ALICE experiment announces first results from LHC’s lead-ion collisions

Symmetry: It's More Like a Guideline

“The code is more what you’d call “guidelines” than actual rules.” — Barbossa, Pirates of the Caribbean: Curse of the Black Pearl There’s some minor rumblings in the physics blogosphere about the latest research results announced this week from Brookhaven’s Relativistic Heavy Ion Collider (RHIC). No, not about the record-breaking temperatures that created another quark-gluon…… Continue reading Symmetry: It's More Like a Guideline
