夸克物质中的“宇宙射线“

"Cosmic Rays" from Quark Matter

Kyle Lawson

摘要:

我描述了一个基于qcd物理学的暗物质候选者,其中暗物质是由宏观上大的夸克和反夸克物质组成的。这些对象可以具有足够大的低数量密度以避免来自直接检测搜索的约束。虽然不是传统意义上的“重子”,但夸克物质具有强烈的相互作用,并将在地面探测器中产生清晰的信号。由于探测这些天体的前景主要受到探测器截面的限制,大尺度宇宙射线探测器是一个有前途的搜索平台。为此,我描述的基本性质的空气簇射引起的夸克块通过地球的大气层。它将表明,这种簇射在几个重要方面类似于由单一的高能宇宙射线引起的簇射。

英文摘要:

I describe a dark matter candidate based in qcd physics in which the dark matter is composed of macroscopically large "nuggets" of quark and anti-quark matter. These objects may have a sufficiently massive low number density to avoid constraints from direct detection searches. Though not "baryonic" in the conventional sense quark matter is strongly interacting and will produce a clear signal in ground based detectors. As the prospects of detecting these objects are mainly limited by the detector cross-section large scale cosmic ray detectors are a promising search platform. To this end I describe the basic properties of the air shower induced by the passage of a quark nugget through the earth's atmosphere. It will be shown that this shower is similar in several important ways to the shower induced by a single ultrahigh energy cosmic ray.
