Abstract We study 2-to-2 scattering amplitudes of massless spin one particles in d = 4 space-time dimensions, like real world photons. We define a set of non-perturbative observables (Wilson coefficients) which describe these amplitudes at low energi

Abstract We review unitarity and crossing constraints on scattering amplitudes for particles with spin in four dimensional quantum field theories. As an application we study two to two scattering of neutral spin 1/2 fermions in detail. Assuming Mande

We bootstrap the S-matrix of massless particles in unitary, relativistic two dimensional quantum field theories. We find that the low energy expansion of such S-matrices is strongly constrained by the existence of a UV completion. In the context of f

We present ${\ensuremath{\psi}}^{\ensuremath{'}}$MSSM, a model based on a $U(1{)}_{{\ensuremath{\psi}}^{\ensuremath{'}}}$ extension of the minimal supersymmetric standard model. The gauge symmetry $U(1{)}_{{\ensuremath{\psi}}^{\ensuremath{'}}}$, also

A wide variety of unified models predict asymptotic relations at ${M}_{\mathrm{GUT}}$ between the b quark and $\ensuremath{\tau}$ lepton Yukawa couplings. Within the framework of supersymmetric $\mathrm{SU}(4)\ifmmode\times\else\texttimes\fi{}{\mathr

In supersymmetric $E_6$ the masses of the third family quarks and charged lepton, $t-b-\tau$, as well as the masses of the vector-like quarks and leptons, $D-\bar{D}$ and $ L-\bar{L}$, may arise from the coupling $27_3$ x $27_3$ x $27_H$, where $27_3
