String Theory... and this mulitverse speculation... dying a death of a 1000 cuts...
here is more on this...

In this case, physicists were looking for a particular particle called the "strange B meson" (Bs) to break into two more particles, called mu particles (μ+ and μ-). These strange B mesons usually only live for roughly just less than one trillionth of a second before breaking apart (called decaying). Here's where the Standard Model (SM) vs. Supersymmetry (SUSY) argument comes in.
If the SM is correct, about once in every 280 million times the Bs decays, the two μ particles should be detected. The number found by the LHC? Roughly once every 310 million times, with some uncertainty. Very close agreement, especially for such a rare and hard to detect decay.
So what does this say about string theory? If supersymmetry is correct, then this decay should occur far more often. In fact, by establishing this number, nearly all reasonable string theory models have failed in a testable prediction. (Unfortunately this prediction is so technical that it would require its own entire essay to explain.)
SUSY supporters had put forth a number for this prediction. Then, as noted by Peter Woit, they changed it when experimental data ruled them out. Then they were shown wrong and changed it again. Now the third prediction has proven wrong. Soon, we will reach a point where further changes in prediction will leave SUSY, and by extension string theory, practically unobservable to us, thus moving them out of the realm of science. String theory is truly being backed into a corner.
Being a popular and respected field, theoretical SUSY and string research will continue on. If more news like this keeps coming out, however, funding may begin to wane in the coming years. Perhaps this will spawn a fresh theory, both more testable and more accountable.
