论文摘要
我们提出了一种使用Peccei-Quinn（PQ）对称性断裂场的旋转冷凝物和尺寸五算子的旋转冷凝物，该旋转冷凝物为Majorana中微子质量提供。旋转通过SPHALERON过程和Yukawa的相互作用引起了Higgs玻色子和Lepton手性的电荷不对称。尺寸五的相互作用将这些不对称转移到Lepton的不对称性中，然后通过Electroweak Sphaleron过程转移到Baryon不对称中。 QCD axion dark matter can be simultaneously produced by dynamics of the same PQ field via kinetic misalignment or parametric resonance, favoring an axion decay constant $f_a \lesssim 10^{10}$ GeV, or by conventional misalignment and contributions from strings and domain walls with $f_a \sim 10^{11}$ GeV.重子不对称的大小与PQ场的质量相连。在简单的超对称理论中，它独立于紫外线参数，并预测超级合理的质量尺度为$ \ Mathcal {o}（10-10^4）$ tev，取决于中微子的质量，以及在辐射还是物质统治时期的凝胶剂量。我们还构建了一个理论，其中TEV量表是可能的。参数共振可能会产生温暖的轴，并且PQ场的径向分量可能会在罕见的KAON衰减中产生信号，从而在与希格斯混合和深色辐射中产生信号。
We propose a baryogenenesis mechanism that uses a rotating condensate of a Peccei-Quinn (PQ) symmetry breaking field and the dimension-five operator that gives Majorana neutrino masses. The rotation induces charge asymmetries for the Higgs boson and for lepton chirality through sphaleron processes and Yukawa interactions. The dimension-five interaction transfers these asymmetries to the lepton asymmetry, which in turn is transferred into the baryon asymmetry through the electroweak sphaleron process. QCD axion dark matter can be simultaneously produced by dynamics of the same PQ field via kinetic misalignment or parametric resonance, favoring an axion decay constant $f_a \lesssim 10^{10}$ GeV, or by conventional misalignment and contributions from strings and domain walls with $f_a \sim 10^{11}$ GeV. The size of the baryon asymmetry is tied to the mass of the PQ field. In simple supersymmetric theories, it is independent of UV parameters and predicts the supersymmtry breaking mass scale to be $\mathcal{O}(10-10^4)$ TeV, depending on the masses of the neutrinos and whether the condensate is thermalized during a radiation or matter dominated era. We also construct a theory where TeV scale supersymmetry is possible. Parametric resonance may give warm axions, and the radial component of the PQ field may give signals in rare kaon decays from mixing with the Higgs and in dark radiation.
