Exact pp-wave solutions in shift-symmetric higher-order scalar-tensor theories
Masato Minamitsuji
We investigate exact plane-fronted gravitational wave (pp-wave) solutions within the framework of shift-symmetric quadratic-order higher-order scalar--tensor (HOST) theories. These…
Background stability and annual modulation test using PICOLON ultra-pure NaI(Tl) detector
PICOLON Collaboration, K. Kotera, D. Chernyak +20
The dark matter observation claimed by the DAMA/LIBRA experiment has been a long-standing puzzle within the particle physics community. NaI(Tl) crystals with radiopurity comparable…
Stealth black hole solutions in higher-order Maxwell-Einstein theories
Masato Minamitsuji
We study static and spherically symmetric black hole solutions in higher-order Maxwell-Einstein theories. We do not particularly focus on the degenerate classes of theories. For se…
Search for Charged Excited States of Dark Matter with KamLAND-Zen
Zen collaboration, S. Abe, M. Eizuka +64
Particle dark matter could belong to a multiplet that includes an electrically charged state. WIMP dark matter () accompanied by a negatively charged excited state ()…
Abundances of uranium and thorium elements in Earth estimated by geoneutrino spectroscopy
S. Abe, S. Asami, M. Eizuka +64
The decay of the primordial isotopes , , , and have contributed to the terrestrial heat budget throughout t…
Superrotation of Titan's stratosphere driven by the radiative heating of the haze layer
Motoki Sumi, Shin-ichi Takehiro, Wataru Ohfuchi +2
Titan's stratosphere has been observed in a superrotation state, where the atmosphere rotates many times faster than the surface does. Another characteristics of Titan's atmosphere…
PICOLON dark matter search project
K. Fushimi, D. Chernyak, H. Ejiri +21
PICOLON (Pure Inorganic Crystal Observatory for LOw-energy Neutr(al)ino) aims to search for cosmic dark matter by high purity NaI(Tl) scintillator. We developed extremely pure NaI(…
Development of highly radiopure NaI(Tl) scintillator for PICOLON dark matter search project
K. Fushimi, Y. Kanemitsu, S. Hirata +20
The highly radiopure NaI(Tl) was developed to search for particle candidates of dark matter. The optimized methods were combined to reduce various radioactive impurities. The $^{40…
Particle acceleration by ion-acoustic solitons in plasma
Hideki Ishihara, Ken Matsuno, Masaaki Takahashi +1
We propose a new acceleration mechanism for charged particles by using cylindrical or spherical non-linear acoustic waves propagating in ion-electron plasma. The acoustic wave, whi…
