I use Unified Spinor Fields (USF), to discuss the creation of magnetic monopoles during preinflation, as excitations of the quantum vacuum coming from a condensate of massive charged vector bosons. For a primordial universe with total energy $M_p$, and for magnetic monopoles created with a total Planck magnetic charge $q_M=q_P=\pm e∕\sqrt{\alpha }$ and a total mass $m_M$, it is obtained after quantisation of the action that the fine-structure constant is given by: $\alpha =\frac{5}{6}\left(1-\frac{16m_M}{5M_p}\right){\left(\frac{e}{q_M}\right)}^2$. If these magnetic monopoles were with total magnetic charge $q_M=\pm e$ and a small mass $m=m_M∕n$, there would be a large number of small quantum magnetic monopoles which could be candidates to explain the presence of dark matter with a 30.97% of the energy in the primordial universe at the Planck era. The case of milli-magnetically charged particles is also analysed. We demonstrate that magnetic monopoles (MM) with masses less than $3.6\times 10^3$ GeV, can exist with a very small charges of up to $10^{-14}e$, which are quantities of interest for searches to be performed in the ATLAS and MoEDAL experiments.

我使用统一自旋场（USF）讨论预充气过程中磁单极子的产生，作为量子真空的激发来自大量带电矢量玻色子的凝结。对于拥有原始能量的原始宇宙${\mathrm{中号}}_p$，以及使用普朗克总电荷产生的磁性单极子 $q_{\mathrm{中号}}=q_P=\pm Ë∕\sqrt{\alpha }$ 和总质量 ${米}_{\mathrm{中号}}$，在对作用进行量化之后，可以通过以下公式给出精细结构常数： $\alpha =\frac{5}{6}\left(\mathrm{1个}-\frac{16{米}_{\mathrm{中号}}}{5{\mathrm{中号}}_p}\right){\left(\frac{Ë}{q_{\mathrm{中号}}}\right)}^2$。如果这些磁单极带总电荷$q_{\mathrm{中号}}=\pm Ë$ 和一小块 $米={米}_{\mathrm{中号}}∕ñ$，将会有大量小的量子磁单极子，它们可以用来解释普朗克时代原始宇宙中能量占30.97％的暗物质的存在。还分析了带有小磁性电荷的颗粒的情况。我们证明质量小于的磁单极（MM）$3。6\times \mathrm{1个}{0}^3$ GeV可以以很小的电荷存在 $\mathrm{1个}{0}^{-14}Ë$，这是在ATLAS和MoEDAL实验中进行搜索所需的数量。
