Unraveling unparticles through violation of atomic parity and rare beauty
arXiv:0708.2835 · doi:10.1016/j.physletb.2007.09.044
Abstract
We put constraints on unparticle physics, specifically on the scale $Î_\U$ and the scale dimension $d_\U$ of unparticle operators, using (i) measurements of atomic parity violation as well as (ii) branching ratio and CP asymmetry measurements in some rare non-leptonic B decay channels.
