We mainly summarize the results reported in a previous work with Pagano, Amelino- Camelia, Melchiorri and Cooray (JCAP 0908:021,2009), which showed, working within a phenomenological model first proposed by Myers and Pospelov, that presently-available Cosmic Microwave Background (CMB) polarization data can provide Planck-scale sensitivity to quantum-gravity-induced in-vacuo-birefringence effects. We also observe that improvements in sensitivity of a few orders of magnitude is achievable with planned CMB polarization measurements, and we comment on how systematic effects of CMB experiments could influence these constraints.

Abstract
We mainly summarize the results reported in a previous work with Pagano, Amelino- Camelia, Melchiorri and Cooray (JCAP 0908:021,2009), which showed, working within a phenomenological model first proposed by Myers and Pospelov, that presently-available Cosmic Microwave Background (CMB) polarization data can provide Planck-scale sensitivity to quantum-gravity-induced in-vacuo-birefringence effects. We also observe that improvements in sensitivity of a few orders of magnitude is achievable with planned CMB polarization measurements, and we comment on how systematic effects of CMB experiments could influence these constraints.
