Effective description of Nelson-Barr models and the theta parameter
Nelson-Barr theories solve the strong CP problem with CP spontaneously broken at Λ_{CP} and transmitted to the CP conserving version of the SM through vector-like quarks (VLQs). For an arbitrary number of CP breaking scalars and VLQs, we perform the full one-loop matching calculations at Λ_{CP} up to dimension five operators and the relevant matching calculations at the VLQ scale relevant to tracking the contributions to the parameter \barθ. In the EFT after the CP breaking scalars have been…

Ray-tracing image simulations of transparent objects with complex shape and inhomogeneous refractive index
Optical images of transparent three-dimensional objects can be different from a replica of the object's cross section in the image plane, due to refraction at the surface or in the body of the object. Simulations of the object's image are thus needed for the visualization and validation of physical models, but previous image simulations for fluid dynamics showed significant differences from experiments. We report ray tracing image simulations that replicate with high fidelity brightfield micros…

User Perceptions and Attitudes Toward Untraceability in Messaging Platforms
Mainstream messaging platforms offer a variety of features designed to enhance user privacy, such as disappearing messages, password-protected chats, and end-to-end encryption (E2EE), which primarily protect message contents. Beyond contents, the transmission of messages generates metadata that can reveal who communicates with whom, when and how often. In this paper, we study user perceptions of "untraceability", i.e., preventing third parties from tracing who communicates with whom, with the g…
