However, says Martin White, a member of Berkeley Lab, a professor of physics and astronomy at the University of California at Berkeley, and chair of the BOSS science survey team, "We've done the analysis now because we have 90 percent of BOSS's final data and we're tremendously excited by the results." Baryon acoustic oscillations (BAO) are the regular clustering of galaxies, whose scale provides a "standard ruler" to measure the evolution of the universe's structure.

Over the past three years, as part of SDSS-III's Baryon Oscillation Spectroscopic Survey (BOSS), the survey has been specifically seeking out repeated spectra of BAL quasars through a program proposed by Brandt and colleagues.

have calculated the photon energy spectrum and photon polarization in a heavy baryon chiral perturbation theory (HB[chi]PT) including explicit [DELTA] degrees of freedom [3].

Such an approach has been applied to light quark systems with a surprising success [4-6], leading to that model so-called Constituent Quark Model (CQM), which, based on the Gell Mann-Zweig idea, explains meson and baryon bound systems.

The proton is stable, because it's the lightest baryon and the baryon number is conserved.

A new detailed map of cosmic structure created from the Baryon Oscillation Spectroscopic Survey (BOSS) is helping astronomers home in on the nature of dark energy with high precision.

It is relevant to mention in this connection that [[delta].sub.KM] is not sufficient to generate the baryon asymmetry of the universe.

On the other hand, the first-order electroweak phase transitions may solve some cosmological problems, like the generation of the baryon asymmetry of the universe (see recent reviews [6,7]).
