简介:为强子的激发QCD的模型预言让比夸克反夸克介子和原来的quark-parton的三夸克的baryons更复杂的结构当模特儿的异国情调的强子的一个分类。这些包括pentaquarkbaryons,六夸克的H-dibaryon,和tetraquark,混血儿和glueball介子。尽管有广泛的试验性的搜索,任何这些异国情调的配置的不含糊的候选人都没被识别。在另一方面,很多个介子说,似乎是一个质子反质子界限状态的,和包含任何一个charmed-anticharmed夸克的其它配对或bottom-antibottom夸克配对,最近被发现了那也不适合进夸克反夸克介子图画也不匹配启发QCD的exotics的期望的性质。这里,我简短为H-dibaryon从最近的搜索考察结果,并且讨论最新发现的状态的一些性质质子反质子状态和所谓的XYZ介子--并且为常规夸克反夸克介子和预言的QCD异国情调的状态把他们与期望作比较。

简介:我们描述在模糊集合和代数学的亢奋的结构之间的关系。事实上,这篇论文是Davvaz介绍在的想法的继续(模糊集合Syst,117:477-484,2001)并且Bhakat和Das在(模糊集合Syst,80:359-368,1996)。有一个珍视间隔的模糊集合的模糊间隔价值的伪巧合的概念被介绍,这是在模糊集合的一个模糊的点的伪巧合的自然归纳。由使用这个新想法,这个概念珍视间隔(α,β)一个亢奋的模块的模糊sub-hypermodules被定义。这最新定义珍视间隔(α,模糊sub-hypermodule是的β)平常的模糊sub-hypermodule的归纳。我们将学习如此的模糊sub-hypermodules并且考虑一个亢奋的模块的基于含意的珍视间隔的模糊sub-hypermodules。
