just yesterday/today "mini big bang" produced with just begun lead (heavy metal) ion collisions, search for that at news.google.com for related coverage.
or check the lhc blog for a more informal format: http://blogs.uslhc.us/
7 tev was last test energy level in proton-proton collision, which next proton-proton collision phase i believe to start back up in feb and go to at least 8 tev, at which point resulting data analysis (from 6 months to 1 year post that phase) should confirm or deny higgs-boson as theorized (8-10 tev collisions theorized to produce enough data at a rapid enough rate to determine final h-b existence quickly and with finality)
alternate theories regarding collision energy levels needed to produce h-b also exist but require modification to the standard model particles and/or sundry interaction mechanisms as they stand.
currently, evidence may exist in data so far collected (from 3.5 to 7 tev collision phase that just ended) but will take a while (6 months to year) to analyze sufficiently.
final answer: more research needed as yet, but if nothing is forthcoming by feb 2011 (from this last proton-proton phase), status should be determined reliably by end of 2011 early 2012.
