"A never-before-seen signal in a collision at the Large Hadron Collider has
raised hopes that the giant particle accelerator is on the verge of serious
breakthroughs.
A series of high-energy proton-proton collisions observed at the Compact Muon
Solenoid (CMS) detector led to 100 or more charged particles being produced.
These so-called "high multiplicity" collisions were unusual in that the
resulting particles are "correlated" - associated with each other at the moment
of their creation. One interpretation of the results is that the protons are
being forced together at such high energies that the quarks that form them are
released, becoming a free-flowing fluid of quarks and gluons like that which
existed immediately after the big bang.
Similar results were seen when colliding copper ions at the Relativistic Heavy
Ion Collider (RHIC) in the USA. However, the much higher beam power of the LHC
means that similar energy collisions can be achieved even with a single proton,
just 1/63rd of the weight of a copper ion. Scientists at RHIC have interpreted
their results to mean that they have reproduced the super-hot, super-dense
conditions of the universe's first moments. If they are right, and if the LHC's
results are comparable, then the LHC is on course for real achievements.
In November physicists intend to start smashing together lead ions, with an
atomic weight of 207, three times the size of copper. If the simple
proton-proton collisions have been as successful as some are saying, then the
possibilities for what will be unveiled in the lead collisions are huge.
James Gillies, the head of communication at CERN, is cautiously optimistic.
"What's exciting is that the LHC is starting to deliver new physics," he says.
However, he is keen to emphasise that the "big bang" state is just one of many
interpretations of the data. "The other possibilities are much less exciting",
he stresses.
Guido Tonelli, a spokesman for the CMS, said: "[This phenomenon] has never been
seen before in proton-proton collisions..."
Eller så kollapsar vi till ett svart håll snabbare än det tar att säga tulipa
