Leftright SU(4) vector leptoquark model for flavor anomalies
/ Fornal, Bartosz ; Gadam, Sri Aditya ; Grinstein, Benjamín
Building on our recent proposal to explain the experimental hints of new physics in $B$ meson decays within the framework of PatiSalam quarklepton unification, through the interactions of the $(3,1{)}_{2/3}$ vector leptoquark, we construct a realistic model of this type based on the gauge group $\mathrm{SU}(4{)}_{L}\times \mathrm{SU}(4{)}_{R}\times \mathrm{SU}(2{)}_{L}\times U(1{)}^{\prime}$ and consistent with all experimental constraints.

Lepton nonuniversality in B decays and fermion mass structure
/ Grinstein, B. ; Pokorski, S. ; Ross, G.
We consider the possibility that the neutralcurrent B anomalies are due to radiative corrections generated by Yukawa interactions of quarks and leptons with new vectorlike quark and lepton electroweak doublets and new Standard Model singlet scalars. [...]

Weak mixing below the weak scale in darkmatter direct detection
/ Brod, Joachim ; Grinstein, Benjamin ; Stamou, Emmanuel ; Zupan, Jure
If dark matter couples predominantly to the axialvector currents with heavy quarks, the leading contribution to darkmatter scattering on nuclei is either due to oneloop weak corrections or due to the heavyquark axial charges of the nucleons. [...]

Baryon number and lepton universality violation in leptoquark and diquark models
/ Assad, Nima ; Fornal, Bartosz ; Grinstein, Benjamín
We perform a systematic study of models involving leptoquarks and diquarks with masses well below the grand unification scale and demonstrate that a large class of them is excluded due to rapid proton decay. [...]
