Scalar Unparticle Signals at the LHC

Understand

If the scale invariance exists in nature, the so-called unparticle physics may become part of reality.

• The only way to refute or confirm this idea is through the experiments one of which is the Large Hadron Collider (LHC).
• One of the peculiar properties of the unparticle stuff is that it gives striking multi-photon signals which has been studied through only the unparticle self-interactions.
• By considering not only the self-interactions of unparticles but also all the other possible contributions, which are dominant, a detailed study of the processes, within a scalar unparticle scenario, $pp\to 4\gamma$, $pp\to 2\gamma 2g$, $pp\to 2\gamma 2\ell$, $pp\to 4e$, $pp\to 4\mu$ and $pp\to 2e2\mu$ at $\sqrt{s}=14$ TeV at the LHC is carried out.
