扭结形状因子

Kink Form Factors

Jarah Evslin

摘要:

我们利用最近构造的线性化孤子扇形微扰理论计算了超相对论介子在非相对论扭结上弹性散射的形状因子。我们考虑了定域扭结波包和离域动量本征态扭结。在非定域情况下,首项就是经典的扭结解,正如Goldstone和Jackiw所发现的那样。主要的离域量子修正与Gervais,Jevicki和Sakita在$ϕ^4$模型中发现的和Weisz在Sine-Gordon模型中发现的一致。在定域扭结波包的情况下,发现了一些与波包宽度成比例的修正,因此将与扭结波包的介子相干散射有关。

英文摘要:

We use a recently constructed linearized soliton sector perturbation theory to calculate the form factors relevant to the elastic scattering of ultrarelativistic mesons off of nonrelativistic kinks. Both localized kink wave packets and also delocalized momentum eigenstate kinks are considered. In the delocalized case, the leading term is just the classical kink solution, as was found by Goldstone and Jackiw. The leading delocalized quantum correction agrees with that found by Gervais, Jevicki and Sakita in the $ϕ^4$ model and Weisz in the Sine-Gordon model. In the case of localized kink wave packets, some corrections are found which scale with the wave packet width, and so will be relevant for the coherent scattering of mesons off of kink wave packets.
