Controlling for the “look-elsewhere effect”

Expect bold claims at this week’s SUSY 2011 (#SUSY11 on Twitter, maybe) Conference at Fermilab, in Batavia, Illinois. No, I do not have any secret information about some analysis that undoubtedly proves Supersymmetry‘s existence; though, it would be pretty cool if such an analysis does exist. I say this because I came back from a [...]
I sort of embellished for dramatic effect in my last post when I concluded with the statement that: Only more data will tell us the answer to the million dollar question: Is it Standard Model or New Physics? In the case of the \(B_s\) mixing phase, \(\phi_s\) this isn’t strictly true. More data will improve [...]
I’m currently in the middle of two important transitions, one logistical, the other scientific. The logistical transition is my move to CERN. I got stuck in Cambridge for an extra two weeks because of a delay in getting my long-stay visa for France. With help from people on both sides of the Atlantic, I learned [...]
In my last post, I showed that LHCb is the best LHC detector for B physics, using the decay of the \(B_s\) meson into a \(J/\psi\) meson and \(\phi\) meson as an example. Today I’m going to try and explain why we want to study this particular decay and show you our latest result. The [...]

Light sources are the ultimate app for particle physics. Researchers around the world use the powerful X-ray beams that light sources create for materials science, protein structure analysis, historical research, pharmaceutical research and drug development and the list keeps going. Argonne National Laboratory published the following story on August 25, 2011 about contributions that the Advanced Photon Source made to developing a new drug to treat skin cancer.

On Tuesday, Aug. 23, the Tevatron accelerator knew something none of the people operating it knew. It felt what employees didn’t, and it reported the news faster than the media could upload it to the Internet. A 5.9-magnitude earthquake had struck the East Coast, and the super-sensitive Tevatron felt it as it happened about 600 [...]
Fermilab distributed this press release Aug. 25. The physics community got a jolt last year when results showed for the first time that neutrinos and their antimatter counterparts, antineutrinos, might be the odd man out in the particle world and have different masses. This idea was something that went against most commonly accepted theories of how [...]
On Tuesday, Aug. 23, the Tevatron accelerator knew something none of the people operating it knew. A 5.9-magnitude earthquake had struck the East Coast, and the super-sensitive Tevatron felt it as it happened about 600 miles away. It had also registered a similar quake in Colorado the night before.
The physics community got a jolt last year when results showed for the first time that neutrinos and their antimatter counterparts, antineutrinos, might be the odd man out in the particle world and have different masses. This idea was something that went against most commonly accepted theories of how the subatomic world works.
Scientists on an experiment at CERN announced today that there is more to cloud formation than previously thought. Their study, published in the journal Nature, looked at the effects on cloud formation of vapors and cosmic rays in the atmosphere. The results could help improve the accuracy of climate models.
Particles have an inherent spin. We explored the case of fermions (“spin-1/2″) in a recent post on helicity and chirality. Now we’ll extend this to the case of vector (“spin-1″) particles which describe gauge bosons—force particles. By now regular US LHC readers are probably familiar with the idea that there are two kinds of particles [...]

As homage to tape and physics, MIT postdoctoral associate Teppei Katori, who works at Fermilab, created the art piece Selex. Named for a fixed-target charmed baryon experiment that ran in Fermilab’s Tevatron from 1996-97, Selex is part of the exhibit Tape: A Celebration currently showing at the Chicago Art Department in the city’s Pilsen neighborhood.
At the time of the European Physics Conference in July, an intriguing small excess of events was reported in the search for the elusive Higgs boson. Yesterday, as the Lepton-Photon conference in Mumbai, India, opened, these signs appear to be less compelling. What happened? All phenomena we study follow statistical laws and are therefore subject [...]
Today in Mumbai (India), at the Lepton-Photon 2011 Conference, talks announcing new results from LHC were held. Data taking claimed almost doubling of data since July Conference in Grenoble. The results were striking and somewhat unexpected. In order to have an idea you should read this CERN press release and the general mood of people [...]
A new experiment planned at Fermilab will allow researchers to peer into the sub-atomic world of virtual particles and resolve a decade old mystery. The Fermilab muon g-2 experiment will use an intense beam of muons, short-lived particles that are similar to electrons but 200 times heavier.
Have a look at the overview article arXiv:1108.3269 "An introduction to quantum gravity" by Giampiero Esposito.It lists 16 approaches to quantum gravity that were followed in the last 80 years - string theory is one of them. Then it lists their achievements. All are theoretical! Not a single of the achievements is a testable prediction.Yep, quantum gravity is a dead alley. We all can stop reading gr-qc.
It is some days that I am not posting here but there is a very good reason: I am on vacation at Satriano, very near Soverato. These are wonderful places in Italy, in the southern region of Calabria. For your pleasure I post here a couple of photos of the moon on the sea at [...]
This theoretician is too little-known to be named. He dislikes the strand model. But for a simple reason: He thinks that time has two dimensions.This seems too crazy too be true. But some people get paid for saying and writing such nonsense. Modern research is full of nonsense.
TweetWe have shown throughout the Imagineer’s Chronicles and its companion book "The Reality of the Fourth *Spatial* Dimension" there would be numerous theoretical advantages to defining the universe in terms of four *spatial* dimensions instead of four-dimensional space-time. One is that it would allow for the resolution of the conflict between the Newtonian assumption that [...]

When asked what he thought about the strand model , he answered that the strand model of a black hole could not be correct , because it does not work in 5 and 6 . dimensions This answer is worth meditating .

A spin model on a honeycomb lattice points to a much sought after type of quantum spin liquid: the Bose metal. Published Mon Aug 08, 2011
Vongehr is one of those people that wrote papers that nature has two times. He means two-dimensional time. No joke.Experimental backing? Zero. That a guy writing this has studied physics at university is almost unbelievable. Some people have a degree and still cannot count.
Garret Lisi makes the point in a comment in Dorigo's blog. A simple truth.
One can dispute whether the equivalence between the universe and god is accurate. Pantheists assume that universe and god are two words for the same concept. Einstein was a pantheist in this sense.Assuming pantheists are right, the people that talk about the multiverse are reintroducing polytheism. It becomes clear again what a nonsense the concept of multiverse is.<div class="blogger-post-footer"
Searching for the theory of everything with string theory is as promising as searching for it by playing chess. Both string theorists and chess players are extremely smart people. Chess players are impressive. So are string theorists. They have intelligence to spare. All of them talk about their intelligence like pistoleros talk about their guns. They are die-hard machos.The only issue: their occupation does not help finding the theory of everything. Not at all. Being smart does not count in the search.
