Computation in a Topological Quantum Field Theory
... Contrary to Sn , the infinite group Bn has infinitely many one-dimensional irreducible unitary representations, each corresponding to a choice of phase eiθ . We see that for θ = 0 and θ = π we recover bosonic and fermionic particles, but for every other choice of θ we find a new particle. As these ...

EUBET 2014: Applications of effective field theories to particle

We can then formulate an effective theory for their interactions. With it, we have calculated the one-loop ...
