Resonant formation of Lambda(1405) by stopped-K- absorption in d (2009)
Esmaili, J., Akaishi, Y., Yamazaki, T.
We show that the current debate on the position of the quasi-bound K-p state, namely, "Lambda(1405) or Lambda*(1420)", can be solved by measuring experimental observables that involve the transition...
Kaonic Nuclear Systems KbarN and KbarNN as Decaying States (2008)
Akaishi, Y., Myint, K. S., Yamazaki, T.
The formation spectra of model KbarN and KbarNN systems formed by (K-, n) reactions are investigated in order to obtain a theoretical basis for a proper interpretation of experimental data concerning...
Full-coupled channel approach to S=-2 s-shell hypernuclear systems (2005)
Nemura, H., Shinmura, S., Akaishi, Y., Myint, Khin Swe
We describe full-coupled-channel ab initio calculations among the octet baryons for S=-2 s-shell hypernuclei,_{LambdaLambda}^4H,_{LambdaLambda}^5H and_{LambdaLambda}^6He. The wave function includes...
Strange tribaryons as Kbar-mediated dense nuclear systems (2005)
Akaishi, Y., Dote, A., Yamazaki, T.
We discuss the implications of recently discovered strange tribaryons in 4He(stopped-K-, p)S0 (3115) and 4He(stopped-K, n) S1 (3140) within the framework of deeply bound kbar states formed on shrunk...
Full-Coupled Channel Approach to Doubly Strange $s$-Shell Hypernuclei (2004)
Nemura, H., Shinmura, S., Akaishi, Y., Myint, Khin Swe
We describe {\it ab initio} calculations of doubly strange, $S=-2$, $s$-shell hypernuclei ($^4_{\Lambda\Lambda}$H, $^5_{\Lambda\Lambda}$H, $^5_{\Lambda\Lambda}$He and $^6_{\Lambda\Lambda}$He) as a...
We propose new effective inter-nucleon forces with a finite-range three-body operator. The proposed forces are suitable for describing the nuclear structure properties over a wide mass number region,...
Brueckner Rearrangement Effects in $^5_\Lambda$He and $^6_{\Lambda\Lambda}$He (2003)
Kohno, M., Fujiwara, Y., Akaishi, Y.
Rearrangement effects in light hypernuclei are investigated in the framework of the Brueckner theory. We can estimate without detailed numerical calculations that the energy of the $\alpha$-core is...
Stochastic Variational Search for $^{4}_{\Lambda\Lambda}$H (2002)
Nemura, H., Akaishi, Y., Myint, Khin Swe
A four-body calculation of the $pn\Lambda\Lambda$ bound state, $^{\ 4}_{\Lambda\Lambda}$H, is performed using the stochastic variational method and phenomenological potentials. The $NN$, $\Lambda N$,...
Lambda Lambda-XiN Coupling Effects in Light Hypernuclei (2002)
Myint, Khin Swe, Shinmura, S., Akaishi, Y.
The significance of $\Lambda\Lambda$-$\Xi$N coupling in double-$\Lambda$ hypernuclei has been studied. The Pauli suppression effect due to this coupling in $^6_{\Lambda\Lambda}$He has been found to...
High-density \={K} nuclear systems with isovector deformation (2002)
Dote, A., Horiuchi, H., Akaishi, Y., Yamzaki, T.
Using a phenomenological \={K}N potential which reproduces $\Lambda$(1405) as an I=0 bound state of \={K}N, we investigated deeply bound kaonic nuclei, ppnK$^-$ and $^8$BeK$^-$, with the method of...
Nemura, H., Akaishi, Y., Suzuki, Y.
Variational calculations for s-shell hypernuclei are performed by explicitly including $\Sigma$ degrees of freedom. Four sets of YN interactions (SC97d(S), SC97e(S), SC97f(S) and SC89(S)) are used....
Can We Extract Lambda-Lambda Interaction from Two-Particle Momentum Correlation ? (1999)
Ohnishi, A., Hirata, Y., Nara, Y., Shinmura, S., Akaishi, Y.
We analyze the invariant mass spectrum of Lambda-Lambda in $^{12}C(K^-,K^+ Lambda Lambda)$ reaction at P(K^+)=1.65 GeV/c by using a combined framework of IntraNuclear Cascade (INC) model and the...
