In (8), the [bar.p]/p ratio is absent because of the complete strange quark
content of Omega mesons.
But under such incredible densities, these nuclei might transform further (right): The protons and neutrons could dissolve into a quark soup; the quarks could change and regroup to form particles called hyperons, which contain at least one strange quark
; the nuclei could unite in a single quantum state, called a Bose-Einstein condensate; or something else that we haven't imagined could be created.
Strange hadrons, which contain at least one strange quark
(one of the (http://hyperphysics.phy-astr.gsu.edu/hbase/Particles/quark.html) six known "flavors" of quarks ), are produced in much greater numbers than non-strange ones in the presence of the high energy density of quark-gluon plasma.
But the new particle's two quark components--a strange quark
and the antimatter partner of a charm quark--are heavier than those in most other particles, making the particle an ideal target for studying the nuclear strong force that binds the two quarks.
One such bizarre object is termed a strange quark

The plenary presentations review new results from the CLEO III and CLEO-c experiments, developments in pentaquark theory, open problems in heavy quarkonium physics, and the strange quark
sector of chiral perturbation theory.
In combination with measurements of the weak-coupling constant in muon decay, [g.sub.v] provides a value for the [V.sub.ud] which can be compared with high energy experiments in the strange quark
sector to provide important information regarding the completeness of the three-family picture of the standard model through a test of the unitarity of the CKM matrix .
At low energy, the chemical potentials of up and down quarks are consistent but differ from that of strange quark
. At high energy, the three chemical potentials seem to deviate from each other, and they finally approach zero at very high energy.
For instance, on Tuesday, scientists associated with the LHCb collaboration (LHCb is one of the four main detectors located underground in huge caverns on the LHC ring) at CERN revealed they had made the most precise measurement to date of a very rare decay of a particle called Bs0 meson - a heavy particle made of a bottom anti-quark and a strange quark
- into a pair of muons.
The newly discovered Xi-sub-b ([[XI].sup.o.sub.b]) contains a strange quark
, an up quark and a bottom quark.
The interaction involving strange quark
is Cabibbo suppressed due to which the neutrino emission from strange quark
matter can be neglected.
