    More details Close

    In this paper, we construct new models for the Anderson duals $(I\Omega^G)^*$ to the stable tangential $G$-bordism theories and their differential extensions. The cohomology theory $(I\Omega^G)^*$ is conjectured by Freed and Hopkins [FH21 ] to classify deformation classes of possibly non-topological invertible quantum field theories (QFT's). Our model is made by abstractizing certain properties of invertible QFT's, thus supporting their conjecture.

  14. Topological violation of global symmetries in quantum gravity

    Journal of High Energy Physics　2021　(9)　2021/09

    Publisher: Springer Science and Business Media LLC

    DOI： 10.1007/jhep09(2021)036 　

    eISSN： 1029-8479

    More details Close

    Abstract We discuss a topological reason why global symmetries are not conserved in quantum gravity, at least when the symmetry comes from compactification of a higher form symmetry. The mechanism is purely topological and does not require any explicit breaking term in the UV Lagrangian. Local current conservation does not imply global charge conservation in a sum over geometries in the path integral. We explicitly consider the shift symmetry of an axion-like field which originates from the compactification of a p-form gauge field. Our topological construction is motivated by the brane/black-brane correspondence, brane instantons, and an idea that virtual black branes of a simple kind may be realized by surgery on spacetime manifolds.

  15. Atiyah-Patodi-Singer index theorem from axial anomaly

    Kazuya Yonekura

    Prog Theor Exp Phys (2021)　2021/03/19

    DOI： 10.1093/ptep/ptab061 　

    More details Close

    We give a very simple derivation of the Atiyah-Patodi-Singer (APS) index theorem and its small generalization by using the path integral of massless Dirac fermions. It is based on the Fujikawa's argument for the relation between the axial anomaly and the Atiyah-Singer index theorem, and only a minor modification of that argument is sufficient to show the APS index theorem. The key ingredient is the identification of the APS boundary condition and its generalization as physical state vectors in the Hilbert space of the massless fermion theory. The APS $\eta$-invariant appears as the axial charge of the physical states.

  16. General anomaly matching by Goldstone bosons

    Kazuya Yonekura

    Journal of High Energy Physics　2021　(3)　2021/03

    Publisher: Springer Science and Business Media LLC

    DOI： 10.1007/jhep03(2021)057 　

    eISSN： 1029-8479

    More details Close

    Abstract We describe how Goldstone bosons of spontaneous symmetry breaking G → H can reproduce anomalies of UV theories under the symmetry group G at the nonpertur- bative level. This is done by giving a general definition of Wess-Zumino-Witten terms in terms of the invertible field theories in d + 1 dimensions which describe the anomalies of d-dimensional UV theories. The hidden local symmetry $$ \hat{H} $$ , which is used to describe Goldstone bosons in coset construction G/H , plays an important role. Our definition also naturally leads to generalized θ-angles of the hidden local gauge group $$ \hat{H} $$. We illustrate this point by SO(Nc) (or Spin(Nc)) QCD-like theories in four dimensions.

  17. Witten effect, anomaly inflow, and charge teleportation

    Kazuya Yonekura

    2020/10/05

    DOI： 10.1007/jhep01(2021)119 　

    More details Close

    We study a phenomenon that electric charges are "teleported" between two spatially separated objects without exchanging charged particles at all. For example, this phenomenon happens between a magnetic monopole and an axion string in four dimensions, two vortices in three dimensions, and two M5-branes in M-theory in which M2-charges are teleported. This is realized by anomaly inflow into these objects in the presence of cubic Chern-Simons terms. In particular, the Witten effect on magnetic monopoles can be understood as a general consequence of anomaly inflow, which implies that some anomalous quantum mechanics must live on them. Charge violation occurs in the anomalous theories living on these objects, but it happens in such a way that the total charge is conserved between the two spatially separated objects. We derive a formula for the amount of the charge which is teleported between the two objects in terms of the linking number of their world volumes in spacetime.

    Supersymmetry is a very important symmetry of modern high energy physics, and plays a central role in both phenomenology and string theory. The most important consequence of this symmetry is that quantum corrections in quantum field theory tend to cancel. However, this property of supersymmetry causes an apparent contradiction, which is known as the anomaly puzzle. In this article I would like to discuss this anomaly puzzle.

    場の量子論の量子異常における指数定理の重要性はかねてから知られていた。境界が無い多様体上におけるAtiyah-Singerの指数定理は有名だが、非摂動的なアノマリーを記述するのにはそれを拡張したAtiyah-Patodi-Singerの指数定理が重要であることが徐々に認識されてきた。これは境界がある多様体上での指数定理である。 Atiyah-Singerの指数定理は藤川の方法により物理的な導出が知られていた。フェルミオンの軸性変換を行うと経路積分の積分測度が不変でなく、量子異常によって変更を受ける。その事実からフェルミオンのゼロモードの個数をゲージ場の局所的な関数の積分で書ける。私の研究でこの藤川の方法の自然な拡張を行うことにAtiyah-Patodi-Singerの指数定理の物理的な導出を行うことに成功した。 境界がある多様体上では、多様体の内部だけではなく境界からの寄与が加わる。この境界からの寄与の物理的な解釈を見つけることがポイントであった。軸性変換を考えるとそこからネーターの定理によって導かれる電流が存在し、その電荷が軸性変換のチャージを与える。Atiyah-Patodi-Singer指数定理の境界からの寄与はeta不変量という幾何学的不変量で与えられるが、この不変量が、境界条件が定める軸性対称性の電荷によって自然に解釈されることがわかった。これにより、数学的な導出は非常に難しかったAtiyah-Patodi-Singer指数定理を物理的に自然かつ簡単に導出できた。

    今年度はLarge Hadron Collider (LHC)実験において、非常に重要な発見がなされました。素粒子の標準模型においてヒッグス粒子が現在まで唯一未発見でしたが、LHCにおいてヒッグス粒子と解釈可能な新粒子が発見されました。さらにその粒子の質量はおよそ125GeV程度であるということも決定されています。もしこれがヒッグス粒子であるなら、この発見は超対称模型に大きな影響を与えます。超対称標準模型においては、125GeVのヒッグス粒子の質量を最も単純に説明するには超対称パートナーの粒子の質量が従来期待されていた質量より重い10TeV程度である必要があります。 その一方で、超対称性模型の一つとして低エネルギーゲージ伝達機構というものが知られています。通常の超対称模型はグラビトンの超対称パートナーであるグラビティーノが初期宇宙において様々な問題を引き起こしますが、グラビティーノが16eVより軽いときはそのような問題は無いことが知られています。低エネルギーゲージ伝達機構は16eVより軽いグラビティーノを実現できるほぼ唯一の機構でありますが、しかしグラビティーノが16eVより軽いと、単純な模型では超対称パートナーの質量が10TeVほど重くなれないことが知られていました。 私は低エネルギーゲージ伝達機構において125GeVのヒッグス質量が実現する方法を研究しました。その方法の一つは超対称標準模型に新たなシングレット場を導入することです。従来行われてきた導入法では低エネルギーゲージ伝達機構において125GeVのヒッグス質量を説明できないことを示すと同時に、導入法を少し変更すれば125GeVヒッグスを実現できることを示しました。ヒッグス質量125GeVを説明する別の方法として、理論が強結合である場合も調べました。このようなときは、まず強結合の効果で超対称パートナーの質量が10TeVになりうることを示し、さらには強結合な低エネルギーゲージ伝達機構において、従来知られていなかった効果によってヒッグス質量が大きくなることを発見しました。
