Plot Of The Week - Supersymmetric Higgs Bosons Of The Third Kind

Plot Of The Week - Supersymmetric Higgs Bosons Of The Third Kind

Jan 21 2010 | comment(s)

I have no energy today to put together a detailed discussion of a brand new, exciting search for supersymmetric Higgs boson performed in data collected by the CDF experiment at the Tevatron proton-antiproton collider. All I can do for you is to show the interesting result of the search, and give you some very general ideas of what this is and why it is interesting. Maybe tomorrow or Saturday I will be able to pay more justice to the analysis.

Particle Physics In 2020

2010 has just started with the best auspices to bring us exciting new science, and there comes a pledge to forecast what will happen in 2020. Oh, well - rest is not what I became a scientist for.

Making non-trivial predictions today for how will basic research be in subnuclear physics ten years down the line is highly non-trivial. For exactly the opposite reason that it is equally hard in several other fields of research.

Triggering - The Subtle Art Of Being Picky

The success of today's particle physics experiments relies to a surprisingly large extent on a seldom told functionality of the giant apparata that detect the faint echoes of subatomic particles hitting or punching through their sensitive regions: the capability of triggering.

Feynman Explains Quarks With A Burp

"One way of thinking about the confinement problem was suggested by e+ e- annihilation into hadrons. Initially, the virtual photon dissociates into a quark and an antiquark that move with almost the speed of light back-to-back. Feynman had argued that additional pairs would be produced in the region between them, along the line separating the initially produced . The new pairs and original would rearrange and become a bunch of outgoing mesons [...].

New Rare B Decays Nailed By CDF: The Door To New Physics ?

New Rare B Decays Nailed By CDF: The Door To New Physics ?

Jan 13 2010 | comment(s)

The CDF Collaboration has recently produced a new analysis of proton-antiproton collisions at the now second-world-best collision energy of 1.96 TeV. They searched for very rare decays of the B mesons, particles composed of, would you guess, a b-quark and a lighter partner orbiting around each other.
