Symmetry Breaking for Matter Coupled to Linearized Supergravity From the Perspective of the Current Supermultiplet [PDF]

open access: yes, 2001
We consider a generic supersymmetric matter theory coupled to linearized supergravity, and analyze scenarios for spontaneous symmetry breaking in terms of vacuum expectation values of components of the current supermultiplet.

A Constant Voltage/Current CPT System With Lightweight Characteristics for the Unmanned Aerial Vehicle

open access: yesIEEE Access
The large weight of the unmanned aerial vehicle (UAV) could cause a decrease in endurance mileage, while poor anti-offset performance could extend charging time and may even damage onboard equipment.

One loop renormalization for the axial Ward-Takahashi identity in Domain-wall QCD [PDF]

open access: yes, 1998
We calculate one-loop correction to the axial Ward-Takahashi identity given by Furman and Shamir in domain-wall QCD. It is shown perturbatively that the renormalized axial Ward-Takahashi identity is satisfied without fine tuning and the ``conserved ...
