The expected (red solid lines) and the observed (black solid lines) 95% CL upper limits on the product of the cross section for pp $\rightarrow$ t*t* $\rightarrow$ tg t$\gamma$ process as a function of mass for spin-1/2 t*. The blue (inner) and yellow (outer) bands indicate the 68 and 95\% coverage of the expected upper limits. The black dashed lines indicate the theoretical expectations.
