They propose a new method to probe a possible non-local nature of
particle interactions, using Higgs boson measurements at the LHC.
This research was led by PhD graduate students Su, Li and Wu, who
hypothesize that particle interactions are not pointlike by effectively
introducing extended vertices. One can trace the origin of these ideas in
string theory of the 1960's that was introduced to explain the strong
force. The stringy nature of particle interactions motivates the
presence of Regge-like trajectories with the spin=1 state to be
identified with the Z' and W' boson triplet that should be present
close to the energy scale that non-local effects become significant.
