Scalar Casimir Effect on a Two-Dimensional Sphere with a Wu--Yang Magnetic Monopole

Jun-Cheng Zhang, Xiao-Yin Pan, Juhao Wu +1

We investigate the Casimir effect of a complex scalar field on a two-dimensional sphere threaded by a fixed Wu--Yang magnetic monopole at the center. In this background the charged…

Why Barriola--Vilenkin Global Monopoles Cannot Rotate?

Yi Lu, Xiao-Yin Pan, Meng-Yun Lai +1

The Barriola--Vilenkin global monopoles are topological defects predicted by certain grand unified theories and have been extensively studied for their astrophysical and cosmologic…

Finite-Distance Gravitational Lensing of a Global Monopole in a Schwarzschild-de Sitter Spacetime

Yi Lu, Xiao-Yin Pan, Meng-Yun Lai +1

We investigate the gravitational lensing of a Schwarzschild-de Sitter black hole with a global monopole at finite distances. In this asymptotically nonflat spacetime, the deflectio…

Two-loop planar master integrals for NNLO QCD corrections to W-pair production in quark-antiquark annihilation

Wen-Jie He, Ren-You Zhang, Liang Han +6

The planar two-loop scalar Feynman integrals contributing to the massive NNLO QCD corrections for -boson pair production via quark-antiquark annihilation can be classified into…

Mixed QCD-EW corrections to -pair production at electron-positron colliders

Zhe Li, Ren-You Zhang, Shu-Xiang Li +5

The discrepancy between the CDF measurement and the Standard Model theoretical prediction for the -boson mass underscores the importance of conducting high-precision studies on…

On the quantization of AB phase in nonlinear systems

Xi Liu, Qing-hai Wang, Jiangbin Gong

Self-intersecting energy band structures in momentum space can be induced by nonlinearity at the mean-field level, with the so-called nonlinear Dirac cones as one intriguing conseq…
