New Physics With CMS ? Huhm.

New Physics With CMS ? Huhm.

Sep 22 2010 | comment(s)

I devote only a short piece today to the topic of the week -or the month- in particle physics: as many of you already know, yesterday the CMS collaboration has made public the results of their analysis of two-particle correlations, which evidences an effect never seen before in hadronic collisions, and which has been saluted very emphatically by the press around the world.

Greek Versions Of Articles On Demand

Sep 21 2010 | comment(s)

I am currently running an experiment, with multiple aims. I have created a new blog in wordpress, where I intend to publish a translation to modern Greek of selected articles that I have written in the past. The first attempt is already there (work is in progress, though, given my multiple occupations these days). In the blog I also offer to translate older posts on demand.

"If they would only do as he did and publish posthumously, we should all be saved a lot of trouble".

[Maurice Kendall, famous British statistician, talking of Bayesians (statisticians who employ Bayes' theorem and Bayes' approach to statistical inference, particularly related to  the use of "prior beliefs") and of Bayes himself, whose groundbreaking work was only published after his death]

A very important new theoretical study has appeared last Tuesday in the hep-ph preprint arxiv. Titled "Precise Predictions on W+4 Jet Production at the Large Hadron Collider", it is signed by a strong team of theorists: C. Berger, Z. Bern, L. Dixon, F. Febres Cordero, D. Forde, T. Gleisberg, H. Ita, D. Kosower, and D. Maitre.

I believe it may be quite useful if I review here the paper results, and explain to you why they are very important for the physics of the LHC. But first, I feel that there are a few details concerning the process of W+jets production at the LHC which might be obscure to most of you. Let me straighten them out -it is worthwhile to do it!

It is unfortunate that whenever I have personal stuff to post as a blog here I have nothing else to choose as a tag than the uninformative "random thoughts"... I wish the posting interface in our beautiful site had a wider selection of tags, including ones such as "stuff that does not interest anybody but selected few", or "my own darn business". But perfection is not of this world, that is until Hank decides to work on his seventh day as well.

A very important new theoretical study appeared yesterday in the hep-ph preprint arxiv.
Titled "Precise Predictions on W+4 Jet Production at the Large Hadron Collider", it is signed by a strong team of theorists: C. Berger, Z. Bern, L. Dixon, F. Febres Cordero, D. Forde, T. Gleisberg, H. Ita, D. Kosover, and D. Maitre. I will try to summarize its importance for the physics of the Large Hadron Collider in accessible terms tomorrow; for the time being I just wish to point it out for those who are capable of reading the paper but are too lazy to check the arxiv daily. I know, you belong to this set but you won't admit it!
