Unlike in photon, invariant masses of graviton or gluon are zero; the Higgs boson is a massive particle with a mass in the range of
125 GeV/c2 -126 GeV/c2. Therefore, a large amount of energy is needed to create a Higgs boson. In a particle accelerator, charged particles are accelerated and strike against each other. As a result, the energy of the particles is converted into mass according to the Einstein equation E = mc2 . In order to create a Higgs boson, a particle accelerator must be able to accelerate the particles very close to the speed of light because Higgs boson is a massive particle. However, in 2013, the Large Hadron Collider (LHC) at CERN announced that they had succeeded in discovering the Higgs particle. Even though the standard model isn’t a completely acceptable story of matter and energy, the existence of the Higgs particle confirmed some other important predictions of the standard model: the existence of the Higgs field, the Higgs mechanism, and the way particles acquire their mass.
The strings in the string theories may be either closed or open strings or both. One can start to develop a string theory from any type of these strings.
If he wants to develop a string theory only for bosons, it is a bosonic string theory. A bosonic string theory explains all the fundamental interactions except matter. The bosonic string theory is a theory of 26 dimensions. But if someone wants to develop a string theory which is capable of explaining all the fundamental interactions as well as matter, a special symmetry between the bosons (force carriers) and the fermions (matter particles) called “supersymmetry” is needed. Such a string theory is known as a “superstring theory.” There are five types of superstrings theories, and they are still being developed. The latest revolution in the string theory is “the M-theory” which is still under development.
