“It’s a great day to be a particle physicist,” said CERN1 Director General Rolf Heuer. “A lot of people have waited a long time for this moment, but their patience and dedication is starting to pay dividends.”
Is the Higgs mechanism for generating elementary particle masses via electroweak symmetry breaking indeed realised in nature?
Is supersymmetry, an extension of the Standard Model and Poincaré symmetry, realised in nature, implying that all known particles have supersymmetric partners?
Are there extra dimensions, as predicted by various models inspired by string theory, and can we detect them?
Are electromagnetism, the strong nuclear force and the weak nuclear force just different manifestations of a single unified force, as predicted by various Grand Unification Theories?
Why is gravity so many orders of magnitude weaker than the other three fundamental forces?
Are there additional sources of quark flavours, beyond those already predicted within the Standard Model?
Why are there apparent violations of the symmetry between matter and antimatter?
What was the nature of the quark-gluon plasma in the early universe? .
Look who's back from tour.
