Anatomical-Guided Attention Enhances Unsupervised PET Image Denoising Performance

Yuya Onishi, Fumio Hashimoto, Kibo Ote +4

Although supervised convolutional neural networks (CNNs) often outperform conventional alternatives for denoising positron emission tomography (PET) images, they require many low-…

Direct positron emission imaging: ultra-fast timing enables reconstruction-free imaging

Ryosuke Ota, Sun Il Kwon, Eric Berg +7

Positron emission tomography, like many other tomographic imaging modalities, relies on an image reconstruction step to produce cross-sectional images from projection data. Detecti…

Missing-mass spectroscopy with the $^{6}$ Li( $π^{-}, K^{+}$ )X reaction to search for $_{Λ}^{6}$ H

R. Honda, M. Agnello, J. K. Ahn +63

We searched for the bound state of the neutron-rich $Λ$ -hypernucleus $_{Λ}^{6}$ H, using the $^{6}$ Li( $π^{-}, K^{+}$ )X double charge-exchange reaction at a $π^{-}$ beam momentum o…

Observation of the " $K^{-} pp$ "-like structure in the $d (π^{+}, K^{+})$ reaction at 1.69 GeV/ $c$

Yudai Ichikawa, Tomofumi Nagae, Hiroyuki Fujioka +41

We have observed a " $K^{-} pp$ "-like structure in the $d (π^{+}, K^{+})$ reaction at 1.69 GeV/ $c$ . In this reaction $Λ (1405)$ hyperon resonance is expected to be produced as a doorway to fo…

Inclusive spectrum of the $d (π^{+}, K^{+})$ reaction at 1.69 GeV/c

Yudai Ichikawa, Tomofumi Nagae, Hyoungchan Bhang +41

We have measured an inclusive missing-mass spectrum of the $d (π^{+}, K^{+})$ reaction at the pion incident momentum of 1.69 GeV/ $c$ at the laboratory scattering angles between 2$^\circ…

Status report of the Tokyo axion helioscope experiment

Y. Inoue, M. Minowa, Y. Akimoto +3

We have searched for solar axions with a detector which consists of a 4T x 2.3m superconducting magnet, PIN-photodiode X-ray detectors, and an altazimuth mount to track the sun. Th…
