Matter-parity as a residual gauge symmetry: Probing a theory of cosmological dark matter
Physics Letters B, 2017 We discuss a non-supersymmetric scenario which addresses the origin of the matter-parity symmetry, PM=(−1)3(B−L)+2s, leading to a viable Dirac fermion dark matter candidate.

Chiral Photocurrent in Parity-Violating Magnet and Enhanced Response in Topological Antiferromagnet
Physical Review X, 2021 Rectified electric current induced by irradiating light, a so-called photocurrent, is an established phenomenon in optoelectronic physics. In this paper, we present a comprehensive classification of the photocurrent response arising from the parity ...

Parity-Time-Anyonic Coupled Resonators System With Tunable Exceptional Points
IEEE Access, 2019 The Hermiticity of physical observable is the fundamental axioms in quantum mechanics. However, it is found that several non-Hermitian Hamiltonian still have real eigenvalues, especially the parity-time symmetric system.

Probing the Planck Scale with Proton Decay [PDF]
, 2004 We advocate the idea that proton decay may probe physics at the Planck scale instead of the GUT scale. This is possible because supersymmetric theories have dimension-5 operators that can induce proton decay at dangerous rates, even with R-parity ...

RK(⁎) from RPV-SUSY sneutrinos
Nuclear Physics B, 2023 We analyze the lepton flavor universality violation (LFV) in process b→sℓ+ℓ− in an R-parity violating supersymmetric (RPV-SUSY) scenario. The most recent update on RK from the LHCb collaboration suggests approximately 3.1σ deviation from the Standard ...

Muon-proton Colliders: Leptoquarks, Contact Interactions and Extra Dimensions [PDF]
, 2000 We discuss the physics potential of the $\mu p$ collider; especially, leptoquarks, leptogluons, R-parity violating squarks, contact interactions, and large extra dimensions. We calculate the sensitivity reach for these new physics at $\mu p$ colliders of

Towards the precision measurement of CP violation in B → D * μν decays at LHCb
Journal of High Energy Physics, 2023 Measurement of CP-violating observables in semileptonic decays is a sensitive null-test of the Standard Model: any CP violation would be an unambiguous sign of New Physics effects.

Emergent spin-valley-orbital physics by spontaneous parity breaking [PDF]
Journal of Physics: Condensed Matter, 2016 The spin-orbit coupling in the absence of spatial inversion symmetry plays an important role in realizing intriguing electronic states in solids, such as topological insulators and unconventional superconductivity. Usually, the inversion symmetry breaking is inherent in the lattice structures, and hence, it is not easy to control these interesting ...

Negative Parity Baryons in the QCD Sum Rule [PDF]
, 1997 Masses and couplings of the negative parity excited baryons are studied in the QCD sum rule. Separation of the negative-parity spectrum is proposed and is applied to the flavor octet and singlet baryons.
