Preference Estimation via Opponent Modeling in Multi-Agent Negotiation
Yuta Konishi, Kento Yamamoto, Eisuke Sonomoto +8
Automated negotiation in complex, multi-party and multi-issue settings critically depends on accurate opponent modeling. However, conventional numerical-only approaches fail to cap…
Anisotropies in Cosmological 21 cm Background by Oscillons/I-balls of Ultra-light Axion-like Particle
Masahiro Kawasaki, Kazuyoshi Miyazaki, Kai Murai +2
Ultra-light axion-like particle (ULAP) with mass has recently been attracting attention as a possible solution to the small-scale crisis. ULAP forms…
Free Streaming Length of Axion-Like Particle After Oscillon/ I-ball Decays
Kaname Imagawa, Masahiro Kawasaki, Kai Murai +2
Axion-like particles (ALPs) are pseudoscalar bosons predicted by string theory. The ALPs have a shallower potential than a quadratic one, which induces the instability and can form…
Probing Oscillons of Ultra-Light Axion-like Particle by 21cm Forest
Masahiro Kawasaki, Wakutaka Nakano, Hiromasa Nakatsuka +1
Ultra-Light Axion-like Particle (ULAP) is motivated as one of the solutions to the small scale problems in astrophysics. When such a scalar particle oscillates with an $\mathcal{O}…
Oscillons of Axion-Like Particle: Mass distribution and power spectrum
Masahiro Kawasaki, Wakutaka Nakano, Hiromasa Nakatsuka +1
In string theory, the simultaneous existence of many Axion-Like Particles (ALPs) are suggested over a vast mass range, and a variety of potentials have been developed in the contex…
Revisiting oscillon formation in KKLT scenario
Shinta Kasuya, Masahiro Kawasaki, Francis Otani +1
KKLT scenario has succeeded in stabilizing the volume modulus and constructing metastable de Sitter (dS) vacua in type IIB string theory. We revisit to investigate the possibility…
