Properties of subatomic 'soup' that mimics the early universe

By teasing out signatures of particles that decay just tenths of a millimeter from the center of a trillion-degree fireball that mimics the early universe, nuclear physicists smashing atoms at the Relativistic Heavy Ion Collider ...

'Fire-streaks' are created in collisions of atomic nuclei

At very high energies, the collision of massive atomic nuclei in an accelerator generates hundreds or even thousands of particles that undergo numerous interactions. Physicists at the Institute of Nuclear Physics of the Polish ...

New CERN results show novel phenomena in proton collisions

In a paper published today in Nature Physics , the ALICE collaboration reports that proton collisions sometimes present similar patterns to those observed in the collisions of heavy nuclei. This behaviour was spotted through ...

Proton-nuclei smashups yield clues about 'quark gluon plasma'

Findings from Rice University physicists working at Europe's Large Hadron Collider (LHC) are providing new insight about an exotic state of matter called the "quark-gluon plasma" that occurs when protons and neutrons melt.

Eavesdropping on the particular chatter on the sub-atomic world

Much like two friendly neighbors getting together to chat over a cup of coffee, the minuscule particles in our sub-atomic world also come together to engage in a kind of conversation. Now, nuclear scientists are developing ...

How did the proton get its spin?

Calculating a proton's spin used to be an easy college assignment. In fact, Carl Gagliardi remembers answering that question when he was a physics graduate student in the 1970s. But the real answer turned out not to be simple ...

New portal to unveil the dark sector of the Universe

Once upon a time, the Universe was just a hot soup of particles. In those days, together with visible particles, other particles to us hidden or dark might have formed. Billions of years later scientists catalogued 17 types ...
