Search for the dark photon in $B^{0} \to A^{'} A^{'}$ , $A^{'} \to e^{+} e^{-}$ , $μ^{+} μ^{-}$ , and $π^{+} π^{-}$ decays at Belle

S. -H. Park, Y. -J. Kwon, I. Adachi +216

We present a search for the dark photon $A^{'}$ in the $B^{0} \to A^{'} A^{'}$ decays, where $A^{'}$ subsequently decays to $e^{+} e^{-}$ , $μ^{+} μ^{-}$ , and $π^{+} π^{-}$ . T…

Two-Gap Time Reversal Symmetry Breaking Superconductivity in Non-Centrosymmetric LaNiC2

Shyam Sundar, S. R. Dunsiger, S. Gheidi +13

We report a $μ$ SR investigation of a non-centrosymmetric superconductor (LaNiC $_{2}$ ) in single crystal form. Compared to previous $μ$ SR studies of non-centrosymmetric superconductin…

Identification of Methyl Isocyanate and Other Complex Organic Molecules in a Hot Molecular Core, G31.41+0.31

Prasanta Gorai, Ankan Das, Takashi Shimonishi +4

G31.41+0.31 is a well known chemically rich hot molecular core (HMC). Using Band 3 observations of Atacama Large Millimeter Array (ALMA), we have analyzed the chemical and physical…

Measurement of time-dependent CP violation parameters in $B^{0} \to K_{0}^{S} K_{0}^{S} K_{0}^{S}$ decays at Belle

Belle Collaboration, K. H. Kang, H. Park +202

We measure the time-dependent $C P$ violation parameters in $B^{0} \to K_{S}^{0} K_{S}^{0} K_{S}^{0}$ decays using $772 \times 1 0^{6}$ $B {\mkern 1.5mu\overline{\mkern-1.5mu B \mkern-…

Latent heat and pressure gap at the first-order deconfining phase transition of SU(3) Yang-Mills theory using the small flow-time expansion method

Mizuki Shirogane, Shinji Ejiri, Ryo Iwami +5

We study latent heat and the pressure gap between the hot and cold phases at the first-order deconfining phase transition temperature of the SU(3) Yang-Mills theory. Performing sim…

Calculable microscopic theory for $^{12}$ C( $α, γ$ ) $^{16}$ O cross section near Gamow window

Y. Suzuki

$^{12}$ C $(α, γ)^{16}$ O radiative-capture process is a key reaction to produce the element of oxygen in stars. Measuring the cross section near the Gamow window is extremely hard be…
