论文摘要
重新加热过程中量子质量和反颗粒对的产生和振荡导致全息和巨大的对等离子体状态。该等离子体中颗粒和反颗粒密度的扰动形成声波,其特征在于对称和不对称密度对比。通过得出声波方程并识别最低的扰动模式(零波数)的频率,研究表明,与地平线大小相比,这些模式的波长表明在重新加热过程中超级术交叉的可能性。这种交叉导致地平线内观察者可观察到的粒子 - 抗粒子不对称。大规模颗粒和抗粒细胞腐烂到重子,产生了净baryon数量,可能解释了重生。计算出的Baryon数量与室内比与观察数据保持一致。该交叉还解释了当前宇宙中暗物质粒子 - 抗粒子的不对称性。该研究还探索了非零波数的扰动模式,代表了深色的声波。这些模式退出了地平线并在重组后重新进入,并有可能在大长度尺度上印在物质功率谱上,并影响大型结构和星系的形成。
Quantum massive particle and antiparticle pair production and oscillation during reheating result in a holographic and massive pair plasma state. Perturbations in the densities of particles and antiparticles within this plasma form acoustic waves, characterized by symmetric and asymmetric density contrasts. By deriving the acoustic wave equations and identifying the frequencies of the lowest-lying perturbation modes (with zero wave number), the study shows that the wavelengths of these modes, when compared with the horizon size, suggest the possibility of superhorizon crossing during reheating. This crossing leads to particle-antiparticle asymmetry observable by an observer inside the horizon. The decay of massive particles and antiparticles into baryons generates a net baryon number, potentially explaining baryogenesis. The calculated baryon number-to-entropy ratio aligns with observational data. This crossing also accounts for dark matter particle-antiparticle asymmetry in the present Universe. The study also explores perturbation modes with nonzero wave numbers, representing dark-matter acoustic waves. These modes exited the horizon and re-entered after recombination, potentially imprinting on the matter power spectrum at large length scales and influencing the formation of large-scale structures and galaxies.
