Here's a basic explanation as to what the Higgs is.
"The Higgs boson or Higgs particle is a proposed elementary particle in the Standard Model of particle physics. The Higgs boson is named after Peter Higgs who, along with others, proposed the mechanism that predicted such a particle in 1964. The existence of the Higgs boson and the associated Higgs field explain why the other elementary particles in the standard model have mass." -wiki
