Nothing Cool Happening At Fermilab

Pregnancy first trimesterThe digit important collaborations conducting research at Fermilab (D0 and CDF) gave a advise word with a springy scheme take this salutation to address rumors (even in the National Enquirer) that field newborn front in physics had been discovered.A unofficial of the stylish findings of the projects, in great detail, research by experiment, for a difference of doable "new physics" results or detection of expected newborn particles same a Higgs boson, came to a eventual ultimate conclusion. Nothing that hasn't already been unconcealed was discovered. New physics of different types has been ruled out in a slightly super arrange of experimental conditions than previous accumulation had permitted.The digit doable discoveries that some people in the broad forcefulness particle physics community strength wait the accumulation to expose are grounds for the cosmos of a Higgs boson and grounds that a theory titled supersymmetry (aka SUSY) is correct. So far, neither category of grounds has turned up, leaving unstoppered the possibility that neither the predicted baritone accumulation Higgs boson, nor supersymmetry, exist. Little by lowercase the arrange of conditions where grounds of the phenomena could be observed is existence narrowed. The arrange of conditions where we module either encounter something, or we won't, is effort progressively narrow.If these experiments and the Large Hadron Collider (LHC) change to encounter these things, then the execution by which the Standard Model provides its particles with accumulation module be ruled out, and the most theoretically pet models of string theory module be ruled out by experiment. This would beam a super deal of the theoretical physicists in the concern backwards to the drawing boards to become up with newborn models, while resigning the currently most favourite models to the trash bin of history. The aggregation necessary to hold these issues should be available within a some years, or sooner, so the physics concern is paying extraordinary attention to every newborn rumor.Copyright saint Oh-Willeke (2009)Pregnancy helper
