DESCRIPTION:As particle physicists we usually think about small fluctuatio
 ns of fields\, but the phenomenology of our theories can depend crucially 
 on the global structure of the field space. First I'll discuss an ambiguit
 y in the Standard Model gauge group\, whose different versions make differ
 ent model-independent predictions for the existence of fractionally charge
 d particles. Such signatures at the LHC merit further attention from exper
 imentalists and phenomenologists\, as these particles can both reveal the 
 structure of the SM\, and falsify theories of unification. Then I'll turn 
 to axion theories and\, as an example\, the DFSZ model\, where careful exa
 mination of global properties of the scalars and the gauge group can affec
 t the structure of axion strings\, and resolve the cosmological domain wal
 l problem.\n\nhttps://indico.ific.uv.es/event/8416/
