What are the mysteries that still remain in particle physics? 
It's amazing to think that our world is based on a handful of fundamental particles and forces. Find out how it all fits together. 
Research into the bizarre world of neutrinos helps to piece together the creation story of the Universe. 
The 2013 Nobel prize in physics goes to Peter Higgs and François Englert for proposing the mechanism that gives things mass. 
"It's a great day for particle physics," says Ben Allanach, a theoretical physicist at the University of Cambridge. "It's very exciting, I think we're on the verge of the Higgs discovery." And indeed, it seems like the Large Hadron Collider at CERN has given particle physics an early Christmas present — compelling evidence that the famous Higgs boson exists. 
Are we close to finding the Higgs? Ben Allanach explains it is not about catching a glimpse of the beast itself, but instead keeping a careful count of the evidence it leaves behind. 
The mathematical maps in theoretical physics have been highly successful in guiding our understanding of the universe at the largest and smallest scales. Linking these two scales together is one of the golden goals of theoretical physics. But, at the very edges of our understanding of these fields, one of the most controversial areas of physics lies where these maps merge: the cosmological
constant problem.
