Recently, a model of gauge mediation with sequestered supersymmetry (SUSY) breaking was proposed. In this model, the mass of the gravitino is O(100) GeV without causing the flavor-changing neutral-current problem. In contrast to traditional gauge mediation, the gravitino is not the lightest SUSY particle, and the neutralino is the candidate of the dark matter. In this paper, we investigate phenomenological aspects of the model and discuss the possibility of the direct detection of the dark matter. In particular, we focus on the light neutralino case and find that the light-Higgsino scenario such as the focus point is interesting in the light of the recent CDMS result.

Witten effect, anomaly inflow, and charge teleportation

Hajime Fukuda, Kazuya Yonekura

Summary: This study examines the phenomenon of charge teleportation between two spatially separated objects without exchanging charged particles, which is achieved through anomaly inflow and implies the presence of anomalous quantum mechanics. Despite charge violation in the anomalous theories living on these objects, the total charge between the two spatially separated objects remains conserved.

General anomaly matching by Goldstone bosons

Kazuya Yonekura

Summary: In this paper, we show how Goldstone bosons can reproduce anomalies of UV theories under the symmetry group G at the nonperturbative level through a general definition of Wess-Zumino-Witten terms. The hidden local symmetry (H) over cap, used to describe Goldstone bosons in the coset construction G/H, plays a crucial role and leads to generalized theta-angles of the hidden local gauge group (H) over cap. This concept is illustrated using SO(N-c) (or Spin(N-c)) QCD-like theories in four dimensions.

Revisiting electroweak radiative corrections to b → sll in SMEFT

Motoi Endo, Satoshi Mishima, Daiki Ueda

Summary: This study revisits electroweak radiative corrections to Standard Model Effective Field Theory (SMEFT) operators relevant to B-meson semileptonic decays. One-loop matching formulas onto the low-energy effective field theory are provided without imposing any flavor symmetry, showcasing gauge independence in the R-xi gauge especially when dealing with quark-flavor mixings.

Topological violation of global symmetries in quantum gravity

Kazuya Yonekura

Summary: The paper discusses a topological reason why global symmetries are not conserved in quantum gravity, particularly when originating from compactification of a higher form symmetry. This mechanism is purely topological and does not necessitate any explicit breaking term in the UV Lagrangian. It is noted that local current conservation does not imply global charge conservation in a sum over geometries in the path integral.

The Atiyah-Patodi-Singer index theorem from the axial anomaly

Shun K. Kobayashi, Kazuya Yonekura

Summary: The paper provides a simple derivation of the Atiyah-Patodi-Singer (APS) index theorem and its generalization using the path integral of massless Dirac fermions. It shows that APS boundary conditions and their generalizations can be identified as physical state vectors in the Hilbert space of the massless fermion theory, with the APS eta-invariant representing the axial charge of the physical states.

Non-resonant new physics search at the LHC for the b → cτν anomalies

Motoi Endo, Syuhei Iguro, Teppei Kitahara, Michihisa Takeuchi, Ryoutaro Watanabe

Summary: Motivated by anomalies in b -> c tau(nu) over bar processes, we study non-resonant searches for new physics at the LHC involving tau leptons, b-jets, and missing transverse momentum. The analysis explores both effective field theory frameworks and explicit leptoquark models, finding sensitivity to leptoquark mass and improved detection capabilities over conventional searches. Probing the parameter space suggested by anomalies and investigating angular correlations among particles are key considerations for discriminating between different scenarios.

Anomaly Inflow and p-Form Gauge Theories

Chang-Tse Hsieh, Yuji Tachikawa, Kazuya Yonekura

Summary: The focus of this study is on the gravitational and Green-Schwarz type anomalies of chiral and non-chiral p-form gauge fields. These anomalies naturally arise as boundary modes of higher-dimensional bulk topological phases. By computing the Atiyah-Patodi-Singer eta-invariant, we provide a systematic description of the total bulk-boundary system, analogous to the realization of a chiral fermion on the boundary of a massive fermion. The SL(2, Z) anomaly of the 4D Maxwell theory is determined using our formalism, and we also investigate the worldvolume theories of D-branes and M5-branes in different string, M, and F theories.

Global anomalies in 8d supergravity

Yasunori Lee, Kazuya Yonekura

Summary: In this paper, we study the gauge and gravitational anomalies of fermions and 2-form fields on eight-dimensional spin manifolds. By using spectral sequence techniques, we classify possible global gauge anomalies and identify their explicit generator manifolds. It is found that fermions in the adjoint representation of any simple Lie group and gravitinos in 8d N = 1 supergravity theory have anomalies. We also discuss how the anomalies of 2-form fields cancel against the fermion anomalies in certain supergravity theories, as well as how the gravitino anomalies are canceled by topological degrees of freedom in another class of theories.

Heterotic global anomalies and torsion Witten index

Kazuya Yonekura

Summary: We study the structure of anomalies in general heterotic string theories by considering general 2-dimensional N=(0,1) supersymmetric quantum field theories. The results show that perturbative anomalies correspond to the Witten index of SQFTs, while global anomalies correspond to a torsion version of the Witten index.

Cosmic F- and D-strings from pure Yang-Mills theory

Masaki Yamada, Kazuya Yonekura

Summary: We discuss the formation of cosmic strings or macroscopic color flux tubes after the deconfinement/con-finement phase transition in the pure Yang-Mills theory. These cosmic strings, based on holographic dual descriptions, can be interpreted as F-strings or D-strings in the gravity side, depending on the structure of the gauge group. The reconnection probabilities of F- and D-strings are suppressed by factors of 1/N^2 and e^-cN, respectively, in the large-N limit. The formation of color flux tubes after the phase transition is similar to the formation of local cosmic strings after spontaneous symmetry breaking in the weak-U(1) gauge theory. We use a velocity-dependent one-scale model to describe the dynamics of the string network and calculate the gravitational wave signals from string loops, considering the dependence on the size of produced string loops.

Cosmic strings from pure Yang-Mills theory

Masaki Yamada, Kazuya Yonekura

Summary: This study discusses the formation of cosmic strings or macroscopic color flux tubes in the phase transition from the deconfinement to confinement phase in pure Yang-Mills theory. The holographic dual descriptions suggest that the cosmic strings are related to fundamental strings or wrapped D-branes in gravity side, with reconnection probability being suppressed. The study shows that the pure YM theory provides a simple realization of cosmic F-and D-strings.

New physics interpretation of W-boson mass anomaly

Motoi Endo, Satoshi Mishima

Summary: Recently, the CDF Collaboration reported an updated result on the measurement of the W-boson mass, which showed a deviation of 7 sigma from the standard model prediction. This discrepancy may indicate the presence of new contributions to the Fermi coupling constant. Simple extensions of the standard model were studied, and it was found that the tension implies the existence of new physics at multi-TeV scales if the new coupling to the electron and/or muon is of order unity.
