Physicist Sean Carrol gave a talk on Particles, Fields and The Future of Physics
at Fermilab in July 2013. In his talk, he describes that particles are actual energy vibrations in the field corresponding to the particle. An electron is actually a energy vibration in the electric field, for example. In the LHC when to protons collide, they generate enough energy in near by fields to cause a vibration in the Higgs field which in turn causes a Higgs boson particle to form. The Higgs boson is detected by looking for its energy as it decays into other particles as it excites other field to produce the decay particles.
