任意长度的触发,Gopakumar-Vafa不变量和5d Higgs分支

Flops of any length, Gopakumar-Vafa invariants, and 5d Higgs Branches

Andrés Collinucci, Mario De Marco, Andrea Sangiovanni, Roberto Valandro

摘要:

圆锥形是非紧卡-丘三重态的一个基本例子,它允许一个简单的翻转,在M理论中,在低能量下产生一个5d超多重态,由一个包裹在消失球上的M2-膜实现。我们开发了一种新的规范理论方法来构造新的例子类,将简单的触发器推广到所谓的长度l=1,.,6.该方法允许我们自然地读出Gopakumar-Vafa不变量。虽然它们与心爱的锥状结构具有相似的性质,但这些三重结构预计将允许更高程度的M2束缚态。我们证明了这一点,通过我们的GV不变量的计算。此外,我们充分表征相关的希格斯分支计算其尺寸和风味群。通过我们的技术,我们提取了更精确的数据,例如风味组下的hypers的电荷。

英文摘要:

The conifold is a basic example of a noncompact Calabi-Yau threefold that admits a simple flop, and in M-theory, gives rise to a 5d hypermultiplet at low energies, realized by an M2-brane wrapped on the vanishing sphere. We develop a novel gauge-theoretic method to construct new classes of examples that generalize the simple flop to so-called length l=1,...,6. The method allows us to naturally read off the Gopakumar-Vafa invariants. Although they share similar properties to the beloved conifold, these threefolds are expected to admit M2-bound states of higher degree. We demonstrate this through our computations of the GV invariants. Furthermore we fully characterize the associated Higgs branches by computing their dimensions and flavor groups. With our techniques we extract more refined data such as the charges of the hypers under the flavor group.
