The Real Discovery Of The Omega B Released By CDF Today!

In the last few days I indulged in a rather technical description of the checks I made on DZERO's evaluation of the significance of their observation of Omega_b particles. In those occasions I did not discuss either what the Omega_b is, nor what is i ...

CDF Vs. DZERO: And The Winner Is...

Last Tuesday CDF announced their own discovery of the Omega_b baryon, a measurement which creates a controversy with the competing experiment at the Tevatron collider, DZERO. That is because DZERO had already claimed discovery for that particle, almost one ...

Tevatron Higgs Limits Strengthened By A New Theoretical Study

A new paper in the Arxiv attracted my attention this morning. It is titled "Perturbative QCD effects and the search for a signal at the Tevatron", and is authored by a set of quite distinguished theorists: C.Anastasiou, G.Dissertori, M.Grazzini, ...

Holographic Dark Universe

When Albert Einstein constructed his general theory of relativity he decided to resort to some reverse engineering and introduced a 'pressure' term in his equations. The value of this pressure was chosen such that it kept the general relativisti ...

Another First Observation for CDF!

The "new" section of experimental physics papers in the arxiv today features a preprint by the CDF collaboration, titled "First Observation of Vector Boson Pairs in a Hadronic Final State at the Tevatron Collider". This is another insta ...

Hadronic Dibosons Seen. Next Stop: The Higgs!

This is going to be a rather long piece, so for the lazy and the absent-minded among you I decided to put together an executive summary at the top, and not at the bottom of the article as I usually do. It is a bit of a spoiler, but those of you who can inv ...

True Muonium- A 'What If...?' Conversation In Physics

'True muonium' is a long-theorized but never-seen tiny atom that was first proposed more than 50 years ago.  True muonium, which unlike "muonium" (an atom made of an electron and an anti-muon) is made of a muon and an anti-muon.   Both ...
