Publikasi Jurnal : Phenomenology of Dark Matter and Mirror Fermions from a Left–Right Mirror Model with Singlet Scalar

We investigate a left–right mirror model with SU(3)c × SU(2)L × SU(2)R × U(1)Y and a discrete  symmetry, which introduces mirror fields that are copies of the standard model (SM) fields. The mirror fields have the opposite chirality to their SM counterpart fields. We also introduce singlet scalars as dark matter (DM). The new interaction between DM, SM fermions, and mirror fermions can account for DM abundance, charged lepton flavor violation, lepton anomalous magnetic moment, and flavor changing neutral current. We demonstrated that if we choose DM annihilation into muon as the dominant annihilation channel for leptophilic DM, both the observed DM abundance and the observed discrepancy between theory and experiment in the muon anomalous magnetic moment can be explained without contradicting the bound derived from charged lepton flavor violating processes. We briefly discuss how mirror fermions will be produced at the future linear collider, as mirror fermions can interact with neutral gauge bosons in this model. Finally, we discuss the lightest mirror neutrino decay mechanism, which will be highly abundant if stable.

Online SAKURA Exchange Program 2022

Mie University (MU) Japan together with Gadjah Mada University (UGM), Bandung Institute of Technology (ITB) and The National Research and Innovation Agency (BRIN). have held an online SAKURA exchange program (SEP) from 5 to 6 January 2022 with the theme: “Asian-materials-network for sustainable development to the next-generation technology in informatics communication and energy”. SEP is an annual program organized together with the Department of Physics–UGM, Department of Physics–ITB, and BRIN. It was the second time this program was being held online due to the pandemic situation. read more
