摘要：

本文利用SU（3）格点量子色动力学中的广义威尔逊圈研究了奇异静态三体势。对于夸克-反夸克-胶子技术，我们解决的角度为0，45，60，90，120，135和180度，夸克-胶子和反夸克-胶子段之间。我们计算了静电势的形式，讨论了三个不同物体之间是否存在两体相互作用，并研究了弦之间是否存在斥力。我们还首次研究了三胶子系统中的相互作用。

英文摘要：

We study exotic static 3-body potentials, utilizing generalized Wilson Loops in SU(3) lattice QCD. For the quark-antiquark-gluon techniques we address the angles of 0, 45, 60, 90, 120, 135 and 180 degrees, between the quark-gluon and the antiquark-gluon segments. We calculate the form of the static potential and discuss whether, or not, two-body interactions exist between the three different bodies, and study the existence of repulsion between the strings. We also perform a first study of the interactions in the system of three gluon.

静态极限下的格点量子色动力学与三体奇异系统

Lattice QCD and Three-Body Exotic Systems in the static limit

用格点量子色动力学方法计算了夸克-反夸克-胶子和3-胶子系统的静态势。对于夸克-反夸克-胶子混合介子，在不同的夸克-胶子段和反夸克-胶子段夹角下，得到了静态势。模拟支持小角度伴随弦的形成，而对于大角度，伴随弦被连接胶子和夸克的两个基本弦取代。对于3-胶子胶球，我们讨论了相应的威尔逊圈，并证明了当胶子相距较远时，胶子之间是由基本弦连接的。

奇异强子态和全对全夸克传播子

Exotic hadronic states and all-to-all quark propagators

讨论了用传播夸克获得精确强子谱的方法。通过比较自旋-奇异混合介子的质量测定与胶球质量测定，我们得出结论：夸克传播子从所有位置到所有其他位置将使误差得到很大改善。这样的传播是可以实现的，通过使用随机估计。我们讨论了以前的尝试，并提出了我们的最大方差减少的方法。这是一个非常有前途的技术，我们说明它通过获得的$b$夸克是静态的极限的基态和激发B介子的光谱。

Charmonium and exotics from lattice QCD

We review selected lattice results on the charmonium spectrum and first attempts to search for the existence of exotic states. The hadro-quarkonium model was proposed to interpret some of the exotic states as a quarkonium core inside a hadron. We present a lattice study of the hadro-quarkonium model in the limit of static quarks. The charm quark decouples in low energy observables and binding energies of charmonium. In a model calculation we are able to evaluate the corrections to decoupling of the charm quark in the continuum.

The phenomenology of the exotic hybrid nonet with $π_1(1600)$ and $η_1(1855)$

We study the decays of the $J^{PC}=1^{-+}$ hybrid nonet using a Lagrangian invariant under the flavor symmetry, parity reversal, and charge conjugation. We use the available experimental data, the lattice predictions, and the flavor constraints to evaluate the coupling strengths of the $π_1(1600)$ to various two-body mesonic states. Using these coupling constants, we estimate the partial widths of the two-body decays of the hybrid pion, kaon and the isoscalars. We find that the hybrid kaon can be nearly as broad as the $π_1(1600)$. Quite remarkably, we find also that the light isoscalar must b…

格点量子色动力学中的氘核和奇异两体束缚态

The Deuteron and Exotic Two-Body Bound States from Lattice QCD

本文介绍了用高统计多体积格点量子色动力学研究介子质量为m ~ 390 MeV的氘核、双中子、H重子和Xi-Xi系统的结果。计算采用各向异性nf = 2+ 1Clover离散，在空间范围L ~ 2.0，2.5，3.0和4.0fm的四个格子体中进行，空间方向的格子间距b_s ~ 0.123fm，时间方向的格子间距b_t ~ b_s/3.5。发现Xi-Xi-受到B_{Xi-Xi-} = 14.0（1.4）（6.7）MeV的束缚，与基于唯象模型和受核子-核子和超子-核子散射数据约束的低能有效场论的预期一致在物理轻夸克质量下。我们发现弱的证据表明，氘核和双中子都束缚在这个π介子质量，结合能分别为B_d = 11（05）（12）MeV和B_{nn} = 7.1（5.2）（7.3）MeV。随着测量次数的增加和分析的精细化，我们得到了H-双重子的结合能B_H = 13.2（1.8）（4.0）MeV，更新了我们以前的结果。

Strong decays of the explicitly exotic doubly charmed $DDK$ bound state

Nowadays, it is generally accepted that the $DK$ interaction in isospin zero is strongly attractive and the $D_{s0}^*(2317)$ can be described as a $DK$ molecular state. Recent studies show that the three-body $DDK$ system binds as well with a binding energy about 60$\sim$70 MeV. The $DDK$ bound state has isospin $1/2$ and spin-parity $0^-$. If discovered either experimentally or in lattice QCD, it will not only provide further support on the molecular nature of the $D_{s0}^*(2317)$, but also provide a way to understand other exotic hadrons expected to be of molecular nature. In the present wor…

Three-body unitarity versus finite-volume $π^+π^+π^+$ spectrum from lattice QCD

Strong three-body interactions above threshold govern the dynamics of many exotics and conventional excited mesons and baryons. Three-body finite-volume energies calculated from lattice QCD promise an ab-initio understanding of these systems. We calculate the three-$π^+$ spectrum unraveling the three-body dynamics that is tightly intertwined with the $S$-matrix principle of three-body unitarity and compare it with recent lattice QCD results. For this purpose, we develop a formalism for three-body systems in moving frames and apply it numerically.

Exotic resonances of fully-heavy tetraquarks in a lattice-QCD insipired quark model

Fully-heavy tetraquark states, i.e. $cc\bar{c}\bar{c}$, $bb\bar{b}\bar{b}$, $bb\bar{c}\bar{c}$ ($cc\bar{b}\bar{b}$), $cb\bar{c}\bar{c}$, $cb\bar{b}\bar{b}$, and $cb\bar{c}\bar{b}$, are systematically investigated by means of a non-relativistic quark model based on lattice-QCD studies of the two-body $Q\bar{Q}$ interaction, which exhibits a spin-independent Cornell potential along with a spin-spin term. The four-body problem is solved using the Gaussian expansion method; additionally, the so-called complex scaling technique is employed so that bound, resonance, and scattering states can be trea…
