1. Implications of the field-theoretic approach to the perfect fluid.Towards the end of the previous fiscal year a reformulation of the perfect fluid was developed. This time, we further expand on the consequences this formalism. Our field-theoretic description allows for the creation and annihilation of fluid itself even within the classical framework; for instance, some class of gauge coupling enables to describe the radiation and absorption of the gauge field accompanied by the change of the intrinsic-mass energy of fluid. We have found that the Lagrangian density governing the dynamics of the fluid contains four phases and incompressible states, two of which are stable. These novel phases are allowed without violation of causality and are discussed within the context of a two-fluid systems. Results were presented at COSMO-16 and are to be submitted for publication.2. Leptogenesis in Chern-Simons modified gravityIn this part, we concentrate on tests of dynamical Chern-Simons (CS) modified gravity, which is currently only weakly constrained by binary pulsar observations. dCS gravity has also been shown to lead to a theory with torsion, in the presence of fermions this torsion corrections result into new two-fermion point interactions. This interaction, mediated by the axial current, was studied in the problem of neutrino-antineutrino asymmetry during the inflationary period. The net particle per helicity was calculated and translated into baryon asymmetry, this quantity dependent on the theta-parameter is constrained by WMAP observations on baryogenesis, work in progress.

1。现场理论方法对完美流体的含义。在上一个财政年度的结束时，已经开发了完美流体的重新制定。这次，我们进一步扩展了这种形式主义的后果。我们的现场理论描述允许在经典框架内创造和歼灭流体本身。例如，某些量规耦合使量规场的辐射和吸收伴随着流体的内在质量能量的变化。我们发现，管理流体动力学的拉格朗日密度包含四个相和不可压缩状态，其中两个稳定。这些新型阶段被允许而不会违反因果关系，并在两流体系统的背景下进行了讨论。结果在Cosmo-16提出，并将提交出版。2。 Chern-Simons修饰重力的瘦素发生在本部分，我们集中于动态Chern-Simons（CS）修饰的重力测试，目前仅受到二元脉冲星观测的薄弱约束。 DCS重力也已显示出具有扭转的理论，在存在fermions的情况下，这种扭转校正导致了新的两效点相互作用。通过轴向电流介导的这种相互作用是在膨胀期间中微 - 抗氨基酸不对称性的问题中研究的。计算每个螺旋度的净粒子并将其转化为重子不对称，该数量取决于theta参数受到wmap观察到的男性生成，正在进行的工作。
