Neutrinophilic DM annihilation in a model with $U (1)_{L_{μ} - L_{τ}} \times U (1)_{H}$ gauge symmetry

Keiko I. Nagao, Takaaki Nomura, Hiroshi Okada +1

We propose a model with two different extra $U (1)$ gauge symmetries; muon minus tauon symmetry $U (1)_{L_{μ} - L_{τ}}$ and hidden symmetry $U (1)_{H}$ . Then, we explain muon anomalous magn…

Strong decays of singly heavy baryons from a chiral effective theory of diquarks

Yonghee Kim, Makoto Oka, Daiki Suenaga +1

A chiral effective theory of scalar and vector diquarks is formulated, which is based on $S U (3)_{R} \times S U (3)_{L}$ chiral symmetry and includes interactions between scalar and vector…

Pseudo-Nambu-Goldstone Dark Matter from Non-Abelian Gauge Symmetry

Hajime Otsuka, Takashi Shimomura, Koji Tsumura +2

We propose a pseudo-Nambu-Goldstone boson (pNGB) dark matter (DM) model based on an additional non-Abelian gauge symmetry $S U (2)_{D}$ . The gauge symmetry $S U (2)_{D}$ is spontaneously b…

Search for Lepton Flavor Violating Decay at FASER

Takeshi Araki, Kento Asai, Hidetoshi Otono +2

FASER is one of the promising experiments which search for long-lived particles beyond the Standard Model. In this paper, we consider charged lepton flavor violation (CLFV) via a l…

Generalized Matter Parities from Finite Modular Symmetries

Tatsuo Kobayashi, Satsuki Nishimura, Hajime Otsuka +2

We classify a supersymmetric extension of the Standard Model by discrete symmetries originating from finite modular symmetries $Γ_{N}$ . Since all the couplings in supersymmetric theo…

Residual flavor symmetry breaking in the landscape of modular flavor models

Keiya Ishiguro, Hiroshi Okada, Hajime Otsuka

We study a symmetry breaking of residual flavor symmetries realized at fixed points of the moduli space. In the supersymmetric modular invariant theories, a small departure of the…

Phenomenological implications on a hidden sector from the Festina Lente bound

Kayoung Ban, Dhong Yeon Cheong, Hiroshi Okada +3

We apply the Festina Lente (FL) bound on a hidden sector with $U (1)$ gauge symmetries. Since the FL bound puts a lower bound on masses of particles charged under the $U (1)$ gauge s…

Scalar Dark Matter with a $μτ$ Flavored Mediator

Kento Asai, Coh Miyao, Shohei Okawa +1

We study a renormalizable scalar singlet dark matter model based on $Z_{4}$ lepton flavor symmetry. A $μτ$ -philic scalar doublet is introduced to explain the discrepancy between the…

Anomaly flow by an Aharonov-Bohm phase

Shuichiro Funatsu, Hisaki Hatanaka, Yutaka Hosotani +2

In gauge-Higgs unification (GHU), gauge symmetry is dynamically broken by an Aharonov-Bohm (AB) phase, $θ_{H}$ , in the fifth dimension. We analyze $S U (2)$ GHU with an $S U (2)$ doublet…

Bhabha scattering in the gauge-Higgs unification

Shuichiro Funatsu, Hisaki Hatanaka, Yutaka Hosotani +2

We examine effects of $Z^{'}$ bosons in gauge-Higgs unification (GHU) models at $e^{+} e^{-} \to e^{+} e^{-}$ Bhabha scatterings. We evaluate differen…

Tau Neutrinos in the Next Decade: from GeV to EeV

Roshan Mammen Abraham, Jaime Alvarez-Muñiz, Carlos A. Argüelles +63

Tau neutrinos are the least studied particle in the Standard Model. This whitepaper discusses the current and expected upcoming status of tau neutrino physics with attention to the…

Doubly heavy tetraquarks in a chiral-diquark picture

Yonghee Kim, Makoto Oka, Kei Suzuki

Energy spectrum of doubly heavy tetraquarks, $T_{QQ}$ ( $QQ q ˉ q ˉ$ with $Q = c, b$ and $q = u, d, s$ ), is studied in the potential chiral-diquark model. Using the chiral e…

4D modular flavor symmetric models inspired by higher dimensional theory

Shota Kikuchi, Tatsuo Kobayashi, Hajime Otsuka +3

We study a scenario to derive four-dimensional modular flavor symmetric models from higher dimensional theory by assuming the compactification consistent with the modular symmetry.…
