'Negatively strange' antihypermatter made out of gold

title is misleading, the gold nucleii collide to create the a quark-gluon-plasma (probably) which eventually cools and condenses to create these new particles which are made from regular old quarks and gluons like every other baryonic particle.

Rather than somehow magically creating a new form of matter from gold.

I guess the exciting part is that they contain a hyperon which is a baryon with one strange quark in it, in this case it looks like a lambda-bar which is gonna be made from anti up, down and strange quarks. Well that and you've managed to bind three of these anti-particles into an anti-Helium or anti-Hydrogen isotope

"negatively strange"

Is that, like, "boring", "commonplace", "average" matter?

I think they just won Buzzword Bingo for the month.

could it mean that some of the galaxies we see are entirely anti-matter galaxies? Woooo.
