Do neutrons become another particle once neutron degeneracy pressure is overcome during a stars collapse, or do they just get compressed?

When collapsing, if the electron degeneracy pressure is exceeded, the electrons and protons become neutrons. If the star is massive enough and continues to collapse, the neutron degeneracy pressure is exceeded and the star becomes a black hole.

Do we know if the neutrons become some other particle once this happens, or are the neutrons just pushed close enough together to exceed the schwarzchild radius and turn the star into a black hole?
