Session A

We study a minimal non-thermal dark matter (DM) model which can explain both the existence of dark matter and baryon asymmetry in the universe. Two color-triplet scalars with O(TeV) mass and a singlet Majorana fermion are required in this study. A new fermion with mass of O(GeV) becomes stable and can play the role of a DM candidate when it is approximately the same mass as proton. In this...

Session A

When building a quantum computer, the classical control system can make the difference between success and failure. In this workshop, we will present several case studies involving researchers at the forefront of quantum technology and discuss the criteria that we consider crucial for the design of control systems matching experimental requirements. For example, with the ever-increasing number...

Session B

Uncovering structural properties of ecological networks is a crucial starting point of studying the system's stability in response to various types of perturbations. We analyze pollination and seed disposal networks, which are representative examples of mutualistic networks in ecosystems, in various scales. In particular, we examine mesoscale properties such as the nested structure, the...

Session B

Time-resolved optically stimulated luminescence (TR-OSL) sensitivity and lifetimes on the various thermal treatment for natural zircon from Brazil were investigated. Analyses of the TR-OSL spectra have showed that the decay is composed of two exponential components with lifetimes depending on the sample treatments. This change of the lifetimes is discussed in terms of a model previously used...

3. Search for flavor-changing neutral current interaction of the top quark and the Higgs boson decaying into bb bar at sqrt[s] = 13 TeV with CMS Run2 data (C)

Session C

We present the results of searching for flavor-changing neutral current (FCNC) in the interaction of top quark and Higgs boson are presented. Large Hadron Collider (LHC) has accumulated proton-proton collision data corresponding to an integrated luminosity of 140 fb-1 at a center-of-mass energy of 13 TeV with the CMS detector during Run2. Using these datasets, the search is performed with the...

4. Excitons in twisted MoSe2/MoSe2 bilayers: the effect of broken mirror symmetry (P)

Poster Session

Van der Waals heterostructures made by stacking dissimilar materials or by introducing a twist angle
between layers can exhibit many exotic properties that are not present from their bulk counterparts.
Indeed, recent experiments on transition metal dichalcogenide (TMD) bilayers suggest that this
structural engineering can lead to periodic confinement of excitons and exciton hybridization....

Poster Session

The 31-MeV proton beams have been delivered from the Holifield Radioactive Ion Beam Facility (HRIBF) at Oak Ridge National Laboratory (ORNL). Excited states in 23Mg were populated through the 24Mg(p,d)23Mg nucleon transfer reactions. By analyzing recoiling deuteron spectra, the excited states of 23Mg could be identified. By requiring coincidences between the reaction deuterons and the decay...
