Higgs Bosons in the centre of Black holes or extremely large stars
No. That's not what a black hole is. A black hole is a vacuum solution to general relativity. In other words a black hole is just mass, without a "thing" left to be massive. The mass is collapsed to a singularity, and is surrounded by an event horizon.

If you pass over the event horizon, every path you can take in will lead you to the singularity. In this sense the singularity is more like a point in time than a point in space. You can't "see" the singularity, since it is always in your future (you can only see things that are in the past)

There is no "thing" at the singularity, There are no protons neutrons or higgs bosons, and any that are formed will find themselves at the singularity, and ceasing to exist in a short time. 

So black holes are very very weird. They can't be easily understood my analogy. They are understood in terms of Einstein's mathematical theory of general relativity.
