Abstract: We discuss a possibility of restricting parameters in N=2 supergravity based on axion observations. We, accordingly, derive conditions that prepotential and gauge couplings should satisfy. Such conditions not only allow us to constrain the theory… read more here.

Abstract: Motivated by the recent Xenon1T result, we study a leptophilic flavor-dependent anomaly-free axionlike particle (ALP) and its effects on charged-lepton flavor violation. We present two representative models. The first one considers that the ALP origins… read more here.

Abstract: Axionlike particles (ALPs) are predicted in many extensions of the standard model, and their masses can naturally be well below the electroweak scale. In the presence of couplings to electroweak bosons, these particles could be… read more here.

DOI: 10.1103/physrevlett.130.111803
Abstract: It is generally believed that global symmetries, in particular, axion shift symmetries, can only be approximate. This motivates one to quantify the breaking of the shift invariance that characterizes the flavorful effective couplings of an… read more here.
