Abstract

Leptoquark (LQ) models are well motivated solutions to the anomaly. In the minimal LQ models, only specific representations can lead to chiral enhancements. For the scalar LQs, and can lead to the top quark chiral enhancement. For the vector LQs, and can lead to the bottom quark chiral enhancement. When we consider the LQ and vector-like quark (VLQ) simultaneously, there can be more scenarios. In our previous study, we considered the scalar LQ and VLQ extended models with up-type quark chiral enhancement. Here, we study the scalar LQ and VLQ extended models with down-type quark chiral enhancement. We find two new models with B quark chiral enhancements, which originate from the bottom and bottom partner mixing. Then, we propose new LQ and VLQ search channels under the constraints of .
