    • Q and lepton symmetries. In this case, a lepton asymmetry is generated, which can be converted into a baryon asymmetry through sphaleron effects. As a concrete example, we discuss this possibility later in detail.

    • note
    • Here we assume that the PQ scalar fields, which are responsible for the spontaneous PQ symmetry breaking in the present universe, have negative mass squared of the order of the Hubble parameter squared during inflation. Then we can avoid the problem of axion domain walls. In addition, cold dark matter can also be explained by the axion in our scenario as a by-product of adopting the PQ symmetry.

    • de [18]. The result for a flat direction which includes squarks will be given in publication [12]. But, while the forms of C and D become more complicated, the essential result does not change.
