    Meson-baryon couplings between positive and negative parity nucleons are investigated using two point correlation functions in the soft meson limit. We find that the πNN* coupling vanishes due to chiral symmetry, while the ηNN* coupling remains finite. We perform an analysis based on the algebraic method for SU(2) chiral symmetry, where nucleon axial charges play an essential role for the above results.

    A technique to treat baryons with negative parity in the QCD sum rule is proposed. The masses of the flavor octet and singlet baryons with J^P = 1/2^- are calculated. We find that the value of the quark condensate determines the scale of the mass splitting of the positive and negative parity baryons. The present sum rule reproduces the observed masses of these baryons within 10%, and predicts the mass of the excited H baryon with J^P = 1/2^- at 1.63 GeV. We confirm that the negative-parity state is ground state in the flavor singlet baryon spectrum.

    This study discusses the role of the chiral symmetry in in-medium hadron properties in order to understand partial restoration of chiral symmetry in nuclear medium systematically and also to establish chiral effective theories for mesons in nuclear matter. The in-medium chiral effective theory for pion is extended to isospin asymmetric nuclear matter and the in-medium quark condensate, pion masses, pion decay constant and wavefunction renormalization are calculated. The estimation of the in-medium modification of kaon by using experimental data for the kaon-nucleon elastic scattering and the investigation of the structure of the eta' mesonic nuclei are performed. In addition, the existence of diquark is discussed by the properties of the heavy hadrons.

    The spontaneously broken chiral symmetry in vacuum is considered to be incompletely restored in finite nuclear density systems with moderate reduction of the magnitude of the quark condensate. The investigation of partial restoration of chiral symmetry in nuclear matter faces two directions: to know the density dependence of the chiral condensate more accurately beyond linear density approximation, to know whether other systems than pion also have partial restoration consistently. In this work, we construct a chiral effective theory in nuclear medium for pion and evaluate the density dependence of the chiral condensate, decay constant and wave function renormalization. We also investigate the in-medium properties of the eta' and K+ meson for the consistency study. We also study the role of the diquark in hadron spectrum, the compositeness of hadron resonances, the nature of Lambda(1405).

    The final goal of this research is to investigate the aspects of the symmetry of the strong interaction by knowing the properties of various mesons at finite density through meson-nucleus systems. The pattern of the symmetry breaking and its restoration are considered to be understood by the relations between various phenomena and properties of various mesons. This kind of study is unique and complementary to that of the high energy heavy ion collisions.
    The main results of this project are the developments of the theoretical studies of (i) the structure and formation of eta(958) meson-nucleus bound states based on eta(958) properties at finite density, (ii) the high precision spectroscopy of the deeply bound pionic atoms, and (iii) the properties of vector mesons at finite density and observables.

    本研究は、ハドロン励起状態(特にエキゾチックハドロン)の構造を、ハドロン動力学による記述とクォーク動力学による解釈とを相補的にとり、個々のハドロンにとってどのような自由度が本質的かを明らかにすることを目的とする。今年度の研究では、反K中間子と核子の準束縛状態と考えられるΛ(1405)共鳴状態の構造を中心課題に、生成反応の散乱断面積の計算やハドロン複合系の記述法やその判定法についての理論的考察を行った。
    1. Λ(1405)の生成反応計算。J-LabやSPring8におけるΛ(1405)光生成反応実験を考察するために、散乱断面積の理論計算を行った。Λ(1405)の光生成機構を有効ラグランジアンの方法でモデル化し、Λ(1405)のエネルギースペクトラムはカイラルユニタリー模型で得られた振幅を用いた。実験で得られているΛ(1405)のエネルギースペクトラムは、カイラルユニタリー模型で得られているもので矛盾なく説明することができ、光生成反応の主成分は、KbarNチャンネルから作られるΛ(1405)であることが分かった。ただ、生成機構は単純でなく、現象論的に接触相互作用を入れないと散乱断面積を再現することが出来なかった。このことより、Λ(1405)光生成機構に核子励起状態の効果などが重要な寄与を与えていると予想される。
    2.共鳴状態の理論的考察。共鳴状態の内部構造の変化をしらべるために、Neuman-Wigner の交差則を共鳴状態への拡張を行った。2準位模型を例にとり、複素エネルギーを持つ2準位からなる系について、性質の変化を制御するパラメータを導入し、性質の変化を追跡した。制御パラメータの複素平面上に存在する"exceptional point"が、構造を議論する上で重要な役割を演じ、共鳴状態の性質の変化が複素数の制御パラメータの幾何学的構造で議論が出来ることを示した。

    The phenomenon of the spontaneous breakdown of chiral symmetry in the QCD vacuum was studied in the aspect of partial restoration of chiral symmetry in nuclear medium. To study the partial restoration, an in-medium chiral effective theory wasdeveloped. The quark condensate and the pion properties in the nuclear medium werecalculated beyond the linear density approximation. The η’ meson in nuclear medium was discussed in the viewpoint of partial restoration of chiral symmetry. It was shown that the η’ meson could have a strong attractive potential in nucleus.

    本研究では、ハドロン分子的状態によるハドロン励起状態について、理論的考察を行った。本年度は主に以下の成果を得ることができた。
    (1)Faddeev法を用いてのハドロン3体系の計算
    カイラル動力学に基づくFaddeev法を用いて、様々な系に対して3体束縛状態を求めた。KKbarK系では、KbarKの強い引力によって3体束縛状態が可能であり、実験的示唆のあるK(1460)に対応すると予想される。また、πKbarKとηKbarKの結合系は共鳴状態を作りπ(1400)がその状態の候補となる。さらに、この3体系から、πとf0(980)との有効相互作用牽引き出すことで、ππf0(980)の3体系を調べ、この状態が最近見つかったf0(1790)に対応する可能性があることがわかった。こめようにハドロン少数系で記述できる状態を選別していくことで、ハドロンの再分類を進めた。
    (2)カイラル動力学におけるハドロンの複合性
    ハドロン励起状態を記述するハドロン模型を用いて束縛状態の構造を議論した。励起ハドロンを記述するのに、ハドロン模型の範囲内で可能なのか、それとも模型空間の外の成分(例えばクォーク成分)が必要であるかを、場の理論の波動関数繰り込み定数を用いて定量的に議論するための枠組みを構築した。また、a1中間子について、ハドロン分子状態とクォーク成分について、large Ncの議論を用いて行った。
    (3)ハドロン中のダイクォーク相関
    ダイクォークをあらわに取り入れたQCD和則を新たに提案し、ハドロン構造に対するダイクォーク相関の重要性を確認する方法を確立した。A、Ac、Abバリオンでは、udスカラーダイクォークがそれらの構造に重要な寄与を与えている一方で、核子やσ中間子では、udダイクォークだけではその質量が再現できず、ダイクォークがuクォークとdクォークに分かれる寄与が必要なことがわかった。

    We have performed theoretical studies for hadrons of new types which have been observed in high-energy accelerator facilities such as KEK and LHC. Baased on Quantum Chromodynamics (QCD), the fundamental theory for the strong interaction, phenomena are described and compared with experimental data. We clarified the mechanism for the generation of the hadrons which have different structure from the well-known nucleons and mesons and that the data indeed indicate the existence of the new hadrons. Furthermore, we have also clarified the fundamental problems of QCD such as confinement and nonperturbative dynamics in the QGP phase.
    For education program, we organized a summer school for young researchers mostly for graduate students from domestic and Asian countries, every year and altogether four times.

    We have studied various meson-nucleus systems theoretically to know the modification of meson properties in nucleus and to understand the aspects of symmetries of strong interaction at finite density. We have obtained the new information on strong interaction effects at finite density, structure of bound states, and formation cross sections for the systems of pionic atoms, Kaonic nuclei,η-,η(958)-, andφ-mesic nuclei systematically. We have also studied the possibility to apply the two nucleon transfer reactions to the formation of the heavy meson and nucleus systems.

    本研究では、ハドロン励起状態の構造に関してハドロン的描像に立って研究を行った。また、バリオン励起状態が重要な役割を担うと予想されている中間子原子核の生成反応や、中間子の核媒質中での性質、エキゾチックハドロンである(-)バリオンの構造に対する研究を行った。主要な研究成果について記す。
    (1) Λ(1405)励起状態の生成反応の理論的研究
    Λ(1405)は生成される過程によって、スペクトラムの形が変わると予想されている。本研究では、反K中間子と重陽子の反応を用いれば、Λ(1405)が反K中間子と核子から生成されることをつきとめ、実験で観測されるスペクトラムの理論的予想を行った。今後、行われる実験に対し重要な示唆を与えた。
    (2) 中間子原子核の生成断面積とK中間子原子核の崩壊過程
    η中間子原子核とK中間子原子核の生成断面積を理論的に計算し、実験で得られる生成スペクトラムの計算を行った。また、Λ(1405)を反K中間子と核子の準束縛状態であるという描像に立って、核媒質中の反K中間子がどのように吸収されるを理論的に予想した。
    (3) 核媒質中でのハドロンの性質
    a1中間子がρとπ中間子のハドロン共鳴であるという立場にたって、核媒質中でのa1中間子の性質を調べた。密度が高くなるにつれ、a1中間子の崩壊幅は大きくなるが、ρ中間子と縮退する傾向であることを確認し、核媒質中でのカイラル対称性の部分的回復の理解に対し重要な示唆を得た。また、中性子星などの高密度状態でπ中間子が凝縮する可能性を、π中間子に対する現在の現象論的知見から検討をし、π中間子凝縮の可能性が小さいことを示した。
    (4) QCD和則における(-)バリオン
    QCD和則を用いて、(-)バリオンの量子数を決定した。実験で観測されている(-)バリオンは、アイソスピン0、スピン3/2、正パリティーを持つ可能性が高いことがわかり、他の量子数を持ったペンタクォーク状態も存在する可能性があることを指摘した。

    本研究では、カイラル対称性とフレーバー対称性をもとに、ハドロン励起状態の構造を理論的に研究することを目的としていた。ハドロンの励起状態の構造は、近年、理論・実験両面から注目を集めている。ハドロン励起状態の構造が、本質的にクォーク自由度で記述されるか、ハドロン自由度で記述され得るかが、構造や性質を理解する上で不可欠である。また、中間子を原子核に入れると中間子は周りの核子を励起して励起状態を作るので、バリオン励起状態の研究は中間子原子核系を理解する上で重要である。今年度の研究では多岐にわたり新たな知見を得ることができた。現在、6本の論文が査読中であり、また、4本の論文を執筆中である。以下に主要な結果についてまとめる。
    1.観測されてる散乱振幅を元に、バリオン励起状態がメゾンとバリオンの準束縛状態で記述されうるか、あるいは別の起源(例えばクォーク)の成分を必要とするかを判定する方法を提示した。その結果、Λ(1405)はメゾンとバリオンの準束縛状態で良く記述されること、N(1535)はメゾンーバリオン以外の成分が必要であることがわかった。
    2.より現象論的な視点に立ってバリオン励起状態の性質について計算を行った。N(1535)励起状態の遷移電気形状因子、Λ(1405)の電磁的平均二乗半径の計算と、Large Ncの議論からΛ(1405)の構造について調べた。
    3.QCD和則の方法を用いてσ中間子は4つのクォークで構成される成分を多くもつことを明らかにした。
    4.η中間子原子核では、N(1535)の原子核中での質量変化に伴って、η中間子モードとN*-holeモードの間のレベル交差が起きうることを示し、η中間子原子核生成反応において、レベル交差が起きているかどうかを観測できることを示した。また、K中間子原子核について、Λ(1405)を考慮に入れて、生成反応スペクトルを計算し、実験との比較を検討した。
