论文摘要
在本文中，我们介绍了一种新型的物质，该物质起源于$ p $ - adic字符串，即带有$ p $ adic世界表格的字符串。我们研究了这种$ p $ - 加法物的某些属性，尤其是其宇宙学方面。我们从$ p $ adic开放字符串的交叉对称散射幅度以及相关的有效的非本地和非线性拉格朗日式，该散布在树级别描述了Tachyon动力学。然后，我们对这个拉格朗日人进行了轻微的修改，并为非tachyonic标量场获得了新的拉格朗日。 {Using this new Lagrangian in the weak field approximation as a matter in Einstein gravity with the cosmological constant, one obtains an exponentially expanding FLRW closed universe.} At the end, we discuss the obtained results, i.e., computed mass of the scalar $p$-adic particle, estimated radius of related closed universe and noted $p$-adic matter as a possible candidate for dark matter.
In this paper, we introduce a new type of matter that has origin in $p$-adic strings, i.e., strings with a $p$-adic worldsheet. We investigate some properties of this $p$-adic matter, in particular its cosmological aspects. We start with crossing symmetric scattering amplitudes for $p$-adic open strings and related effective nonlocal and nonlinear Lagrangian which describes tachyon dynamics at the tree level. Then, we make a slight modification of this Lagrangian and obtain a new Lagrangian for non-tachyonic scalar field. {Using this new Lagrangian in the weak field approximation as a matter in Einstein gravity with the cosmological constant, one obtains an exponentially expanding FLRW closed universe.} At the end, we discuss the obtained results, i.e., computed mass of the scalar $p$-adic particle, estimated radius of related closed universe and noted $p$-adic matter as a possible candidate for dark matter.
