I once was an active chessplayer, but work duties have long taken tournaments off my plate - I simply do not have the time to sit through long hours of chess battles. So I play blitz online on chess.com (my handle is "tommasodorigo", in case you wondered).
I thought it would be good to let you readers of this column know that in case you wish to order the book "Anomaly! Collider Physics and the Quest for New Phenomena at Fermilab" (or any other title published by World Scientific, for that matter) you have 10 more days to benefit of a 35% discount off the cover price. Just visit the World Scientific site of the book and use the discount code WS16XMAS35).
I am spending a week in Israel to visit three physics institutes for colloquia and seminars: the Tel Aviv University (where I gave a colloquium yesterday), the Haifa Technion (where I am giving a seminar today), and the Weizmann institute in Rehovot (where I'll speak next Wednesday).
Today I am actually quite proud of my research institute, the "Istituto Nazionale di Fisica Nucleare, INFN, which leads Italian research in fundamental physics. In fact a selection to hire 73 new researchers with permanent positions has reached its successful conclusion. Rather than giving you my personal opinions (very positive!) I think it is better to let speak the INFN president Fernando Ferroni, and the numbers themselves.
During the past few months I have been giving seminars and colloquia in several institutes around Europe and the US. The topic was more or less always the same, i.e. the discovery criterion used in fundamental physics to decide whether to claim for the observation of a new phenomenon. We set this at 5-sigma -that's, e.g., how the Higgs boson has been discovered in 2012. This is an arbitrary choice, and there is a lot to learn from a study of the history of how the criterion became an established practice, and from the statistical issues it entails.Here is a list of the past events:- Oslo University, October 26- LIP Lisbon, October 27- SLAC laboratory, November 8- Northwestern University, November 11- Royal Holloway University London, November 30
Today while I was having a shower I happened to think at how cool it is that we can actually measure the rate of production, in single hadron-hadron collisions, of multiple elementary particles. A graph like the one below, now routinely produced by ATLAS and CMS whenever they collect more data or switch to a higher center-of-mass energy, looks "natural" to produce, but it is actually surprising that we indeed can pull it off - it requred careful design choices in a number of ways. I wish to discuss one of these here.
In any physicists' new-year wish list there is a mandatory item: the finding of some unexpected, bolt-from-the-blue new physics result - possibly leading to highly-cited publications, press interviews and invitations, and ultimately career advancements or other similar ego boosts. Because we do it for the progress of mankind and the furthering of human knowledge, but we also do it for ourselves- we are human beings too.
As I am traveling around Europe this week, giving seminars in several places (Hamburg yesterday, Berlin today, and Clermont-Ferrand on Friday) my connectivity is erratic and my capability to follow the development of data analysis and new publications is strongly lowered. My connections to the world of LHC research continues through email exchanges, though.
The DZERO collaboration published earlier this year a search for resonances decaying to pairs in its Run-2 dataset of 2-TeV proton-antiproton collisions, produced by the now defunct Tevatron collider in the first 10 years of this century.
I am told that when a patient is diagnosed with a terminal illness, he or she will likely go through a well-defined sequence of stages. The first stage is Denial: the patient will convince him- or herself that there is a mistake in the diagnosis, that somehow the doctors are wrong, or something alike. It is a protective, visceral reaction, one preventing the shock of reckoning with a completely altered landscape. There follows a state of Anger: the "why me" sentiment is the cause of this state of mind. Then there is Fear, brought about by the lack of knowledge of what is coming. Then comes Grief - for oneself as well as for the loved ones. And finally, Acceptance, which brings peace to the soul.
The book "Anomaly! Collider physics and the quest for new phenomena at Fermilab" is about to be published, after a somewhat long and anti-climatic wait. And the first presentation events are being scheduled here and there.If you are at CERN I hope I will see you at the CERN library (bldg 52) on November 29th, at 4PM. The book should already be available for retail by then. On that occasion I will just chat a little about the contents, answer questions, and maybe read one or two paragraphs to those of you who will come by.The event is detailed in this indico page.
Back to my office in Padova, I am looking back at last week's travel around the US and the two talks I delivered at SLAC (the Stanford Linear Accelerator Center) and Northwestern University. The event at SLAC was an experimental seminar. Due to a clash with a "Higgs coupling" workshop that was taking place at the same time, it did not attract a very large audience. Still, it was quite nice to meet a few of the SLAC scientists there, and in particular to chat with Stan Brodsky, a well-known theorist whom I had met in Valparaiso earlier this year. I am also grateful to Brandon Eberly, my host at SLAC, who took care of welcoming me there and introducing the seminar.
As the 23 faithful readers of this blog already know, I recently wrote a book that describes the searches for new physics undertaken by a glorious particle physics experiment, CDF, during the eighties and nineties. The book, titled "Anomaly! Collider physics and the quest for new phenomena at Fermilab", is coming out at the end of November. More information and reviews on the book can be obtained at this link. Or you can directly pre-order the book via AMazon by following the link on the right column here (you may have to scroll down) -->
