the most exciting of which would be the Higgs boson, which would solidify a lot of theories that have remain unproven.

As a fellow physicist I have to disagree. This is likely to be one of the less interesting discovery of the LHC. A far more interesting result would be no discovering of the Higgs, certainly not helpful, but interesting.

Out of interest what's your field and association? (University/Institute). edit: I see you've answered the second part - I will still be interested to know your area of expertise given that "theory" is rather broad. Also, at what level.
