太阳中微子流理论不对称性的半解析计算

A Semi-Analytical Computation of the Theoretical Uncertainties of the Solar Neutrino Flux

Andreas Christ Sølvsten Jørgensen, Jørgen Christensen-Dalsgaard

摘要:

我们提出了一个比较蒙特卡罗模拟和半解析方法,再现太阳中微子通量的理论概率分布函数,源于$pp$,$pep$,$hep$,$^7\mathrm{Be}$,$^8\mathrm{B}$,$^{13}\mathrm{N}$,$^{15}\mathrm{O}$,和$^{17}\mathrm{F}$源反应。我们获得了良好的协议之间的两种方法。因此,半分析方法产生的置信区间,密切匹配那些发现,基于蒙特卡罗模拟,并指向相同的一般对称性的调查概率分布函数。此外,这种方法的计算成本可以忽略不计,这是一个明显的优势,比蒙特卡罗模拟,使其微不足道的新的观测约束的输入参数的考虑。

英文摘要:

We present a comparison between Monte Carlo simulations and a semi-analytical approach that reproduces the theoretical probability distribution functions of the solar neutrino fluxes, stemming from the $pp$, $pep$, $hep$, $^7\mathrm{Be}$, $^8\mathrm{B}$, $^{13}\mathrm{N}$, $^{15}\mathrm{O}$, and $^{17}\mathrm{F}$ source reactions. We obtain good agreement between the two approaches. Thus, the semi-analytical method yields confidence intervals that closely match those found, based on Monte Carlo simulations, and points towards the same general symmetries of the investigated probability distribution functions. Furthermore, the negligible computational cost of this method is a clear advantage over Monte Carlo simulations, making it trivial to take new observational constraints on the input parameters into account.
