Archive for January, 2014. Inclusive W and Z cross sections. Quark density on the basis of inclusive cross section measurements. I’ll return to this result in a future post. Are nearly as precise as the theoretical predictions, whose errors are dominated by the PDF uncertainties. We knew, back in 2011, that a new era of electroweak physics had begun. It is even more interesting to plot the W. Cross section against the W. Cross section, because the asymmetry between W. In a low pile-up configuration in or...

CMS resolves states with a mass difference of 19 MeV | Collider Blog

CMS resolves states with a mass difference of 19 MeV. September 27, 2014 at 4:56 pm. This week the CMS Collaboration released a paper reporting the measurement of the ratio of production cross sections for the χb2(1P) and the χb1(1P) heavy meson states ( arXiv:1409.5761. The motivation stems from the theoretical difficulties in explaining how such states are formed, but for me as an experimenter the most striking feature of the analysis is the impressive separation of the χ states. The mass of the χb...

Archive for October, 2013. Nice, short video on US contributions to CERN Science. I just heard about a youtube video written by Don Lincoln about the role the United States plays in CERN science – specifically, the LHC. You can view it here:. Apparently Ernie Monitz, the new Secretary of Energy, linked this to his facebook page: https:/ www.facebook.com/ErnestJMoniz/posts/222609781237091. October 19, 2013 at 3:23 pm. Blank on the Map. Life on the Lattice. Shores of the Dirac Sea. The CMS kinematic edge.

RÉSONAANCES: Weekend plot: minimum BS conjecture
http://resonaances.blogspot.com/2015/05/weekend-plot-minimum-bs-conjecture.html
Friday, 8 May 2015. Weekend plot: minimum BS conjecture. This weekend plot completes my last week's post. It shows the phase diagram for models of natural electroweak symmetry breaking. These models can be characterized by 2 quantum numbers:. Baroqueness], describing how complicated is the model relative to the standard model;. Specialness], describing the fine-tuning needed to achieve electroweak symmetry breaking with the observed Higgs boson mass. While S≈(Λ/mZ) 2≈10 4. Even further, one has to resort...

Montag, 31. Oktober 2011. The Origin of the Quantum, Part II: Incomplete Evidence. In the previous post. Which has the property that any formal system can only derive finitely many bits of its binary expansion; this is a statement of incompleteness, known as Chaitins incompleteness theorem. Equivalent to the more familiar Gödelian version. The first example is taken from the paper Logical Independence and Quantum Randomness. Continue reading →. Diesen Post per E-Mail versenden.

Montag, 16. Juli 2012. The Origin of Force. As I have expanded upon lengthily in this previous post. Interference is a key phenomenon in quantum theory. In this post, we will see how it can be used to explain the existence of forces between certain objects, using the example of the electromagnetic force in particular. . Continue reading →.

The Ratiocinator: The Interpretation of Quantum Mechanics
http://ratioc1nat0r.blogspot.com/2012/01/interpretation-of-quantum-mechanics.html
Montag, 16. Januar 2012. The Interpretation of Quantum Mechanics. So far on this blog, I have argued that quantum mechanics should be most aptly seen as a generalization of probability theory, necessary to account for complementary propositions (propositions which can't jointly be known exactly). Quantum mechanics can then be seen to emerge either as a generalization (more accurately, a deformation) of statistical mechanics on phase space. Fundamentally, this is a question of what one expects of a physic...
