DMNet International Symposium   

 

The JSPS Core-to-Core Program “International Research Network to Reveal Dark Matter in the Universe by Multidisciplinary Approach in Particle and Astrophysics” (DMNet) started in 2020.
 

The 3rd DMNet international symposium is organized by the INFN-Padova Unit and the Department of Physics and Astronomy "Galileo Galilei"of the Padova University, it will be held at Palazzo Moroni, Padova, Italy from September 26th to 28th, 2023.  

The topics in the 3rd DMNet international symposium are dark matter studies in accelerator physics.  In the 2nd DMNet international symposium, we focused on the direct and indirect detection of dark matter. The direct production of dark matter particles with accelerators is a method to reveal the nature of dark matter, complemental to the direct and indirect detection of dark matter. It might be ultimate since we may reveal the underlying particle physics model with accelerators in addition to the nature of dark matter.

The following topics we will focus of this symposium:

• Latest dark matter and BSM searches at the LHC and the Belle-II
• Prospects of dark matter and BSM searches in future experiments with accelerators including fixed target experiments
• Particle physics models of dark matter
• Latest results of direct and indirect detection of dark matter, complemental to the accelerator physics, and the impact on the dark matter models

15:30 Novel loop-diagrammatic approach to QCD θ parameter and application to the left-right model

When the QCD axion is absent in full theory, the strong CP problem has to
be explained by an additional mechanism, e.g., the left-right symmetry. Even though tree-
level QCD θ ̄ parameter is restricted by the mechanism, radiative corrections to θ ̄ are mostly
generated, which leads to a dangerous neutron electric dipole moment (EDM). The ordinary
method for calculating the radiative θ ̄ utilizes an equation θ ̄ = −arg det mloop based on the q
chiral rotations of complex quark masses. In this paper, we point out that when full theory includes extra heavy quarks, the ordinary method is unsettled for the extra quark contributions and does not contain its full radiative corrections. We formulate a novel method to calculate the radiative corrections to θ ̄ through a direct loop-diagrammatic approach, which should be more robust than the ordinary one. As an application, we investigate the radiative θ ̄ in the minimal left-right symmetric model. We first confirm a seminal result that two-loop level radiative θ ̄ completely vanishes (corresponding to one- loop corrections to the quark mass matrices). Furthermore, we estimate the size of a non- vanishing radiative θ ̄ at three-loop level. It is found that the resultant induced neutron EDM is comparable to the current experimental bound, and the expected size is restricted by the perturbative unitarity bound in the minimal left-right model.
