Yeah, like the Higgs or Supersymmetric partners... but nothing that will prove (or disprove) String theory.
All the existing particles are nothing else, according to the theory, that different modes of vibration of basic entities called strings
The higher the frequency of the vibration, the higher the relevant energy and consequently the higher the mass of the particle
If you deliver a huge amount of energy you should be able to excite modes of vibration which do not normally exist in nature in other words you should create very heavy particles , hundreds time heavier than neutrons or protons
Their lifespam is expected to be just a fraction of time but they should leave a track on the screen of the computers
If their mass, electric charge , spin, etc comply with the predictions of the theory than the theory of string is , very likely true, otherwise it is for sure false
The theory of string is accused to abuse of a sort of math formalism
The scientits have tweaked, so to speak, the equations several times to make them compatible with the experience
Up to a certain extent it is however the same thing also for the standard model
In the equations of the standard model there are 18 constants
In classic physics constant have a physical meaning
Take the equation of the gas, for example
pv = kt
K depends on the type of gas
The 18 constant of the standard model , same as the extra dimensions of the string theory ,apparently have no meaning at all
They have "simply " been introduced to make the results of the equations complying with the experience
The equations of the standard model work perfectly but , nobody knows why...:)
