We discuss the modification of the properties of heavy mesons under extreme conditions of density present in heavy-ion collisions at CBM/FAIR energies. We pay a special attention to the behavior of Tcc(3875) and Ds0(2317) as well as their corresponding antiparticles in a dense nuclear environment, so as to show that the charge-conjugation asymmetry in nuclear matter could become an interesting...
We summarize the relationship between chiral symmetry breaking and the masses of hadrons. Next, we discuss the behavior of vector mesons in matter. Finally, we demonstrate why K1 and K* are appropriate chiral partners that can be realistically measured in experiments.
Femtoscopy is a powerful technique for studying final-state interactions between hadrons, employing two- and three-body correlations to analyze the emission source and final-state interactions of particles with low relative momentum. Recent research by the ALICE collaboration has demonstrated the realization of a common baryon-baryon emission source in pp collisions, opening new avenues for...
I will summarize recent progress in the study of hadron-hadron interactions using lattice QCD near the physical pion mass (146 MeV), focusing on the HAL QCD method and its connection to experimental data. In particular, we highlight several key interaction channels: (i) Baryon-Baryon Interactions in the S=-2 sector, (ii) Meson-Meson Interactions in the D*-D (Tcc) channel, and (iii)...
The hyperon single-particle potential (hyperon potential) is a key ingredient for discussing the properties of hyperons in a dense environment, including their existence in neutron stars. In this talk, we will introduce the hyperon potential in nuclear matter based on the baryon forces within modern chiral effective field theory. We will then discuss the validity of these potentials by...
Hyperon-proton scattering experiment is one of the most direct methods to study the hyperon-nucleon (YN) interaction, as in the case of the NN interaction.
Although it had been experimentally difficult for a long time due to short lifetime of hyperons, we successfully performed high-statistics Σ±p scattering experiment at J-PARC.
More YN scattering data for various channels and observables...
This talk will cover preliminary results from E42 on the H-dibaryon search near the Lambda Lambda and Xi- p mass thresholds. The E42 has collected nearly seven thousand Lambda Lambda production events from (K-, K+) reactions off 12C at 1.8 GeV/c. We are approaching the final stage of data anlysis to open the box. The presentation will discuss the nature of the H-dibaryon with only a small...
"Treating the NAGARA emulsion event in a realistic L-L-4He three-body model, it is found that the LL6He -> H + 4He strong-interaction lifetime becomes much longer than hypernuclear weak-interaction decays for H dibaryon mass below m(L)+m(n), so that a deeply bound H is not in conflict with hypernuclear data.
Using EFT methods, it is found that the H -> nn weak-decay lifetime
for m(H) <...
The $\eta^{\prime}$ meson has an extraordinary large mass among the light pseudo-scalar meson nonet.
The large mass is considered to originate from the non-trivial vacuum structure associated with chiral symmetry breaking and the axial U(1) anomaly in the QCD.
In a nuclear medium, where the chiral symmetry is partially restored, the mass reduction of the $\eta^{\prime}$ meson is predicted by...
Gluonic effects are important in etaprime physics. In this talk I shall discuss the role of gluonic degrees of freedom in possible etaprime bound states in nuclei as well as in the etaprime-nucleon interaction. If experiments see evidence for an etaprime bound state, how do we interpret that it in terms of gluon related parameters? Might the possible very narrow and close to threshold...
Recently, experimental studies of the kaon-induced reactions on deuteron and helium-3 were carried out at J-PARC. The former experiment reported a resonance pole below the KbarN mass threshold in the deduced S-wave KbarN scattering amplitude in the isospin = 0 channel [1]. The pole is naturally interpreted as a KbarN bound state. The latter experiment reported a bump structure below the KbarNN...
The HAL QCD method has been established as a reliable method to study hadron-hadron interactions. However, singular behavior around the origin has been observed in the Kbar N potential, which dynamically generates the Lambda(1405) as the bound state. In order to clarify the cause of such behavior in the HAL QCD method, we calculate the NBS wave functions and R correlators in an effective...
We study the decays $\bar B^0 \to \bar K^0 \, X$, $B^- \to K^- \, X$, $\bar B^0_s \to \eta (\eta')\, X$, $\bar B^0 \to \bar K^{*0} \, X$, $B^- \to K^{*-} \, X$ , $\bar B_s^0 \to \phi \, X$, with $X \equiv X(3872)$, from the perspective of the $X(3872)$ being a molecular state made from the interaction of the $D^{*+} D^-, D^{*0} \bar D^0$ and $c.c.$ components. We consider both the external and...
Hypernucleus is a many-body system with strangeness and is an important probe for discussing nuclear matter based on SUf(3).
In recent years, there have been significant advancements in experimental and theoretical studies for few-body hypernuclei. Discussions of the charge symmetry breaking effect and Sigma mixing effect are currently underway.
The outline of K-long Facility (KLF) at Jefferson Lab will be presented. It has been approved by PAC48 to run for 200 days of the beamtime to measure CQM and LQCD predicted but not established dozens of hyperon states. This facility also allows to study hyperons in nuclei.
