Fitting the exotic hadron spectrum with an additional quark
Scott Chapman
Most of the exotic hidden-charm hadrons discovered over the last 20 years fit neatly into the quark model as normal mesons and baryons if the existence of a seventh flavor of quark…
Twisted Superfields
Scott Chapman
A model is presented that could lead to an interesting extension of the Standard Model. Like a supersymmetric gauge theory, the model is holomorphic and invariant to local superspa…
A New Form of Soft Supersymmetry Breaking?
Scott Chapman
Starting with a supersymmetric U(N)xU(N) gauge theory built in N=1 superspace, a nonsupersymmetric theory is obtained by ``twisting'' the gauginos into a different representation o…
Charmonium tetraquarks and pentaquarks or an additional quark?
Scott Chapman
Most of the exotic hadrons discovered over the last 20 years fit into the quark model as normal mesons and baryons if the existence of a seventh flavor of quark is hypothesized. If…
