More Thoughts On The New CDF Signal

More Thoughts On The New CDF Signal

Apr 07 2011 | comment(s)

Given the wide interest (about 20k readers in a day) that the new article by the CDF collaboration has attracted (see my original post here), I think I should collect in a separate post some auxiliary information, concerning past searches which might have been sensitive to such a signal in the past.

UPDATE (4/7): I posted a link to a nice animated GIF which shows the (approximate) effect of scaling up the MC/data jet energy scale factor on the CDF new particle signal. See here.

UPDATE (4/7): I added some considerations on the tentative CDF signal in a separate post today (4/7). You can find there a comparison with older semileptonic diboson searches at CDF and DZERO.

Thoughts On The Hyperball Algorithm

Apr 02 2011 | comment(s)

I have recently dusted off an algorithm I had invented eight years ago, one I dubbed "Hyperball algorithm". It might come handy for predicting the b-tagging rate in CMS events with jets, for an analysis I am thinking of doing. Since saying more would violate a dozen rules so let's leave it at that, and let me instead describe the old idea... Just for fun.

Farewell - I Quit Blogging

Apr 01 2011 | comment(s)

This is my last post of my blog.

I have decided to totally quit my blogging activities after the last incident. My participation in the scientific collaborations CDF and CMS has always been a problem, since whenever I discussed a topic here even mildly related to their business there was the potential of receiving heat from those colleagues of mine who believe that the scientific integrity of the experiment can be harmed by a blog post, or who imagine that grant reviewers be influenced by what is written by a collaborator in a private blog.

What A Difference An Editor Makes

On today's online version of the highest-diffusion newspaper in Italy, Il Corriere Della Sera (a bit too right-winged for me, but still an important source) stands a piece signed by none less than Carlo Rubbia, Physics Nobel prize in 1984 for the discovery of W and Z bosons. Despite his not so young age any more, Carlo is still extremely active in the field of high-energy physics, where he has moved his interest into neutrino physics.

It has been a while since I last wrote about results from the DZERO collaboration, and I am happy to be given a chance to do so by my casual Monday morning browsing of the most recent Arxiv preprints.
