    Why is mass uncertain in case of Heisenberg Principle?

    I read that for Higgs Boson Heisenberg Uncertainty Principle applies. But why is mass uncertain in case of short lived unstable particle? That being said the momentum is uncertain which tells us that the position is known. Is the position known by measuring the Higgs Bump? Is the velocity also...
