Query: Higgs data does not rule out a sequential fourth generation with an
  extended scalar sector   Contrary to the common perception, we show that the current Higgs data does
not eliminate the possibility of a sequential fourth generation that get their
masses through the same Higgs mechanism as the first three generations. The
inability to fix the sign of the bottom-quark Yukawa coupling from the
available data plays a crucial role in accommodating a chiral fourth generation
which is consistent with the bounds on the Higgs signal strengths. We show that
effects of such a fourth generation can remain completely hidden not only in
the production of the Higgs boson through gluon fusion but also to its
subsequent decay to $\gamma\gamma$ and $ Z\gamma$. This, however, is feasible
only if the scalar sector of the Standard Model is extended. We also provide a
practical example illustrating how our general prescription can be embedded in
a realistic model.
