A tilted brane in theories with large compact extra dimensions leads to spontaneous symmetry breaking of the Lorentz and rotational invariance in four dimensions, as shown by Dvali and Shifman. In this Brief Report, we point out that the mentioned Lorentz symmetry breaking, although leading to CPT-violating interaction terms, cannot lead to CPT violation in the experimentally interesting K-K̄ and analogous systems. ©2000 The American Physical Society.
