Yes, some new particles should pop out if the theory is right...



Yeah, like the Higgs or Supersymmetric partners... but nothing that will prove (or disprove) String theory.

Not all, the standard theory does not include the "graviton" the string thoery does



The Graviton is a concept based on the idea that every fundamental force has a particle carrier... but Gravity is SO different from all the other forces that we have no idea at which energy ranges it exists or even if it DOES exists. Heck, we might as well be searching for Tachyons as they are as "real" as gravitons! Hence nothing at CERN is looking for a Graviton and there are no experiements that I'm aware of that are trying to look for it (Gravity waves on the other hand... )

Moreover you can use the same arguments also against the standard theory




I don't understand which "argument" you are talking "against".

The fine tuning parameter is an unresolved issue and something the String Theory (or any GUT candidate) aims to solve. But that doesn't change the fact that the SM makes predictions that have consistently proven true in the last 50 years, that it's never been proven wrong, and that there are no other theories that have the predictive power the SM has. So whoever this scientist was may have been famous, but as well was famously wrong!

This is why the LHC's search for the Higgs is so critical. If it's not found, it will be a SEVERE blow to the SM... but if it is found, then it will be just another indication that the SM is "right".
