If higgs field is made up of higgs bosons, why do we need proton collisions to create them ? Aren't they present everywhere including vacuum ? Why do they decay to these other particles if it is so fundamental to higgs field ? Why does high's boson have mass (or is it just mass equivalant of energy) ? Does it mean higgs field has mass which in turn means vacuum has mass ? Why is higgs boson heavier than most other particles ?
