Charms of Strongly Interacting Conformal Gauge Mediation
Gongjun Choi, Tsutomu T. Yanagida, Norimi Yokozaki
By extending a previously proposed conformal gauge mediation model, we construct a gauge-mediated SUSY breaking (GMSB) model where a SUSY-breaking scale, a messenger mass, the -…
The Upper Bound of the Second Higgs Boson Mass in Minimal Gauge Mediation with the Gravitino Warm Dark Matter
Gongjun Choi, Tsutomu T. Yanagida, Norimi Yokozaki
A keV-scale gravitino arsing from a minimal supersymmetric (SUSY) Standard Model (MSSM) is an interesting possibility since the small scale problems that CDM model encounters in…
A Model of Interacting Dark Matter and Dark Radiation for and Tensions
Gongjun Choi, Tsutomu T. Yanagida, Norimi Yokozaki
We present a model describing the dark sector (DS) featured by two interactions remaining efficient until late times in the matter-dominated era after recombination: the interactio…
Dark Photon Dark Matter in the minimal Model
Gongjun Choi, Tsutomu T. Yanagida, Norimi Yokozaki
The extension of the Standard model (SM) with three heavy right handed neutrinos, a complex scalar and the gauged symmetry (the minimal model) is considered…
Feebly Interacting Gauge Boson Warm Dark Matter and XENON1T Anomaly
Gongjun Choi, Tsutomu T. Yanagida, Norimi Yokozaki
The recent observation of an excess in the electronic recoil data by the XENON1T detector has drawn many attentions as a potential hint for an extension of the Standard Model (SM).…
XENON1T Anomaly and its Implication for Decaying Warm Dark Matter
Gongjun Choi, Motoo Suzuki, Tsutomu T. Yanagida
An excess in the electronic recoil data was observed in the XENON1T detector. One of plausible explanations for the excess is absorption of a vector bosonic particle with the mass…
