Large Hadron Collider (LHC) tagged posts

Today, exactly ten years after announcing the discovery of the Higgs boson, the international ATLAS and CMS collaborations at the Large Hadron Collider (LHC) report the results of their most comprehensive studies yet of the properties of this unique particle. The independent studies, described in two papers published today in Nature, show that the particle’s properties are remarkably consistent with those of the Higgs boson predicted by the Standard Model of particle physics...

Four-dimensional unsubtraction from the loop-tree duality

Researchers at the universities of Valencia and Florence propose an approach to the experimental data generated by the LHC that solves the infinity problem without breaching the 4 dimensions of space-time. The theories currently used to interpret the data emerging from CERN’s Large Hadron Collider (LHC), which have so far most notably led to the discovery of the Higgs boson, are poorly defined within the four dimensions of space-time established by Einstein in his Theory of Special Relativity. In order to avoid the infinities resulting from the calculations that these theories inspire, new dimensions are added in a mathematical trick which, although effective, does not reflect what we now know about our Universe.

Now though, a group...

Researchers confirm existence of rare ‘exotic’ particle, find evidence of 3 others. Physicists have made science history by confirming the existence of a rare 4-quark particle and discovering evidence of 3 other “exotic” siblings. Their findings are based on data from the Large Hadron Collider (LHC) particle accelerator, CERN, Geneva, Switzerland. The tetraquark candidate is X(4140). The other 3 have higher masses, called X(4274), X(4500) and X(4700).
