Physicists discover family of tetraquarks

Physicists in the Syracuse University College of Arts and Sciences have made science history by confirming the existence of a rare four-quark particle and discovering evidence of three other "exotic" siblings.

Calorimeter components put to the test

Tracking particles created in subatomic smashups takes precision. So before the components that make up detectors at colliders like the Relativistic Heavy Ion Collider (RHIC) get the chance to see a single collision, physicists ...

At the LHC, charmed twins will soon be more common than singles

In the range of energies penetrated by the LHC accelerator, a new mechanism of particle creation is becoming more prominent, say scientists from the Institute of Nuclear Physics of the Polish Academy of Sciences in Krakow. ...

A view of the colorful microcosm within a proton

The proton sounds like a simple object, but it's not. Inside, there's a teeming microcosm of quarks and gluons with properties such as spin and "color" charge that contribute to the particle's seemingly simplistic role as ...

The universe's primordial soup flowing at CERN

Researchers have recreated the universe's primordial soup in miniature format by colliding lead atoms with extremely high energy in the 27 km long particle accelerator, the LHC at CERN in Geneva. The primordial soup is a ...

RHIC particle smashups find that shape matters

Peering into the seething soup of primordial matter created in particle collisions at the Relativistic Heavy Ion Collider (RHIC)-an "atom smasher" dedicated to nuclear physics research at the U.S. Department of Energy's Brookhaven ...

CERN collides heavy nuclei at new record high energy

The world's most powerful accelerator, the 27 km long Large Hadron Collider (LHC) operating at CERN in Geneva established collisions between lead nuclei, this morning, at the highest energies ever. The LHC has been colliding ...

LHC completes proton run for 2015, preps for lead

The Large Hadron Collider (LHC) has successfully completed its planned proton run for 2015, delivering the equivalent of about 400 trillion (1012) proton-proton collisions – some 4 inverse femtobarns of data – to both ...

A particle purely made of nuclear force

Scientists at TU Wien (Vienna) have calculated that the meson f0(1710) could be a very special particle – the long-sought-after glueball, a particle composed of pure force.
