Cool And Interesting Websites 2019

In this article I investigated some of the mid-level and developing automobile websites from US and derived their Search Engine Optimization (SEO) indices and trends. Theorists have calculated that, in the Standard Model, this decay should occur about 3 times in every billion, but that if new particles predicted by theories such as supersymmetry exist, the decay could occur much more often (see news items of 8 April and 22 July 2011 for more details).
Theorists will be busy trying to make sense of this measurement, and seeking for possible associations with other unexpected effects apratamaa found in similar decays, for example the RK anomaly (see 3 June 2014 news ). Stay tuned for future developments on this page.

Last week at the 16th International Conference on B-Physics at Frontier Machines, "Beauty 2016” , Marseille, France, the LHCb collaboration presented the updated result of a measurement of the semileptonic asymmetry, assl, related to a difference between a probability of a beauty meson, B0s, to oscillate into its antimatter partner, B0s, and a probability of the reverse process.
Today at the 37th International Conference on High Energy Physics in Valencia, the LHCb collaboration has presented the first observation of Z boson production in proton-lead collisions at the LHC at a centre-of-mass energy per proton-nucleon pair of 5 TeV.

The results presented today profited from three improvements to the previous analysis: the full 1.0 fb-1 data sample collected in 2011 was used instead of 0.6 fb-1, the analysis technique was improved and also in addition another independent method was used to select matter D and antimatter D particle decays.
Not only was the importance of Higgs boson discovery discussed but also the Beauty meson production inside the LHCb VErtex LOcator ( VELO ). The VELO detector is composed of two halves placed on both sides of proton beams around the proton-proton collision point.
At the underlying quark level a beauty b quark turns into a strange quark s by emitting a photon γ. This famous b→sγ transition is considered as a very interesting process in which signs of new physics could show up. The first evidence for this process was obtained by the CLEO Collaboration in 1993 and since then it was intensively studied in many experiments.

The final name was fixed in 1997 with the cute choice for the LHCb logo Here the cb” is transformed in the mirror image into CP” which is then violated” by the red bar pointing to CP violation ” as the one of the most important themes of LHCb research.
In particular, precise measurements on the difference between the lifetime of D0 mesons, composed of a cu quark pair, and their partner D0 mesons, with opposite quark content cu (when decaying either to a pair of pions or a pair of kaons) were reported, in order to search for CP-violating effects in the Charm sector.
Both measurements are statistically compatible with Standard Model (SM) predictions and allow stringent constraints to be placed on theories beyond the SM. This is one of the most important results obtained by the LHC experiments from the run 1 and tests the SM to the ninth decimal place.

The DsJ(2860)- particles are composed of an anti-charm quark c and a strange quark s. The quark-anti-quark pair is bound by strong interactions and can form different quantum states with different values of spin and angular momentum in analogy to the different quantum states of ordinary atoms.
The LHCb Collaboration presented today at the Rencontres de Moriond QCD , La Thuile, Italy, results of an improved search for the difference between properties of matter and antimatter, CP violation, in charm decays, see 14 November 2011 news for introduction.
