Possible suppression of resonant signals for split universal extra dimensions by mixing at the LHC
Possible suppression of resonant signals for split universal extra dimensions by mixing at the LHC
The mixing of the imaginary parts of the transition amplitudes of nearby resonances via the breakdown of the Breit-Wigner approximation has been shown to lead to potentially large modifications in the signal rates for new physics at colliders. In the case of suppression, this effect may be significant enough to …
