Model analysis on the effectiveness of the HAL QCD method for hadron-hadron interactions

Takayasu Sekihara, Kei Fujiwara

The HAL QCD method has been one of the powerful tools to extract hadron-hadron interactions directly from lattice QCD simulation data. In this paper, we aim at examining the effect…

On max-plus two-sided linear systems whose solution sets are min-plus linear

Yasutaka Ooga, Yuki Nishida, Yoshihide Watanabe

The max-plus algebra $R \cup {- \infty}$ is defined in terms of a combination of the following two operations: addition, $a \oplus b := max (a, b)$ , and multiplication, $a…

Algorithm for the CSR expansion of max-plus matrices using the characteristic polynomial

Yuki Nishida

Max-plus algebra is a semiring with addition $a \oplus b = max (a, b)$ and multiplication $a \otimes b = a + b$ . It is applied in cases, such as combinatorial optimization and discrete…

Short-range baryon-baryon potentials in constituent quark model revisited

Takayasu Sekihara, Taishi Hashiguchi

We revisit the short-range baryon-baryon potentials in the flavor SU(3) sector, using the constituent quark model. We employ the color Coulomb, linear confining, and color magnetic…

Matrix similarity transformations derived from extended $q$ -analogues of the Toda equation and Lotka-Volterra system

R. Watanabe, M. Shinjo, M. Iwasaki

The $q$ -Toda equation is derived from replacing ordinary derivatives with $q$ -derivatives in the famous Toda equation. In this paper, we associate an extension of the $q$ -Toda equa…

All maximal gauged supergravities with uplift

Falk Hassler, Yuho Sakatani

Generalised parallelisable spaces permit to uplift many maximal gauged supergravities to ten or eleven dimensions. While some of the former are explicitly known, the literature is…

Poisson-Lie T-plurality for dressing cosets

Yuho Sakatani

The Poisson-Lie T-plurality is an equivalence of string theories on various cosets $D / G ~$ , $D / G ~^{'}$ , $\dots$ , where $D$ is a Drinfel'd d…

Two-body wave functions and compositeness from scattering amplitudes: II. Application to the physical $N^{}$ and $Δ^{}$ resonances

Takayasu Sekihara

The meson-baryon molecular components for the $N^{*}$ and $Δ^{*}$ resonances are investigated in terms of the compositeness, which is defined as the norm of the two-body wave…

E $_{6 (6)}$ Exceptional Drinfel'd Algebras

Emanuel Malek, Yuho Sakatani, Daniel C. Thompson

The exceptional Drinfel'd algebra (EDA) is a Leibniz algebra introduced to provide an algebraic underpinning with which to explore generalised notions of U-duality in M-theory. In…

An asymptotic expansion of the Casorati determinant and its application to discrete integrable systems

Masato Shinjo, Masashi Iwasaki, Yoshimasa Nakamura

The Hankel determinant appears in the representation of solutions to several integrable systems. Asymptotic expansion of the Hankel determinant thus plays a key role for investigat…
