problems in supersymmetry???
The first results on supersymmetry from the Large Hadron Collider (LHC) have been analysed by physicists and some are suggesting that the theory may be in trouble. Data from proton collisions in both the Compact Muon Solenoid (CMS) and ATLAS experiments have shown no evidence for supersymmetric particles – or sparticles – that are predicted by this extension to the Standard Model of particle physics.
Supersymmetry (or SUSY) is an attractive concept because it offers a solution to the "hierarchy problem" of particle physics, provides a way of unifying the strong and electroweak forces, and even contains a dark-matter particle. An important result of the theory is that every known particle has at least one superpartner particle – or "sparticle". The familiar neutrino, for example, is partnered with the yet-to-be discovered sneutrino. These sparticles are expected to have masses of about one teraelectronvolt (TeV), which means that they should be created in the LHC.
In January the CMS collaboration reported its search for the superpartners of quarks and gluons, called squarks and gluinos, in the detector. If these heavy sparticles are produced in the proton–proton collisions, they are expected to decay to quarks and gluons as well as a relatively light, stable neutralino.

LHC llega a su mejor momento
A comunidad mundial de Físicos que trabaja en el LHC-europa, conseguieron obtener choques de protones generando una energia record de 7 TeV (tera eV ou trillon de eletron volts) a energia máxima proposta cuando fue construida el laboratorio de choque de partículas.
Se estima que ahora, estamos en la condicion de responder a algunas preguntas fundamentales, como la existencia o nó de las particulas de Higgs (boson de Higgs), partícula proposta teóricamente dentro del modelo estandad de la teoria de campos y partículas. Algunos acreditan que conceptos actuales de matéria oscura y energia oscura tambien seran puesta a prueba al analizar los millones de datos obtenidos despues de las coalisiones de protones a altisima energia (record mundial) realizadas este ultimo martes de mes de marzo del 2010.

LHC entra en funcionamiento exitoso
LHC comenzó a funcionar, las pruebas iniciales fueron un suceso segun la pagina oficial del LHC-suiza.
