A Study of Double Dark Photons Produced by Lepton Colliders using High Performance
Computing
The universe is thought to be filled with not only Standard Model (SM) matters
but also dark matters. Dark matter is thought to play a major role in its construction.
However, the identity of dark matter is as yet unknown, with various search methods from
astrophysical observartion to particle collider experiments. Because of the
cross-section that is a thousand times smaller than SM particles, dark matter research
requires a large amount of data processing. Therefore, optimization and parallelization
in High Performance Computing is required. Dark matter in hypothetical hidden sector is
though to be connected to dark photons which carries forces similar to photons in
electromagnetism. In the recent analysis, it was studied using the decays of a dark
photon at collider experiments. Based on this, we studies double dark photon decays at
lepton colliders. The signal channels are e+e– → AʹAʹ and e+e– → AʹAʹγ where dark photon
Aʹ decays dimuon. These signal channels are based on the theory that dark photons only
decay into heavily charged leptons, which can explain the muon magnetic momentum
anomaly. We scanned the cross-section according to the dark photon mass in experiments.
MadGraph5 was used to generate events based on a simplified model. Additionally, to get
the maximum expected number of events for the double dark photon channel, the detector
efficiency for several center of mass (CM) energy were studied using Delphes and
MadAnalysis5 for performance comparison. The results of this study will contribute to
the search for double dark photon channels at lepton colliders.
期刊介绍:
JASS aims for the promotion of global awareness and understanding of space science and related applications. Unlike other journals that focus either on space science or on space technologies, it intends to bridge the two communities of space science and technologies, by providing opportunities to exchange ideas and viewpoints in a single journal. Topics suitable for publication in JASS include researches in the following fields: space astronomy, solar physics, magnetospheric and ionospheric physics, cosmic ray, space weather, and planetary sciences; space instrumentation, satellite dynamics, geodesy, spacecraft control, and spacecraft navigation. However, the topics covered by JASS are not restricted to those mentioned above as the journal also encourages submission of research results in all other branches related to space science and technologies. Even though JASS was established on the heritage and achievements of the Korean space science community, it is now open to the worldwide community, while maintaining a high standard as a leading international journal. Hence, it solicits papers from the international community with a vision of global collaboration in the fields of space science and technologies.
