Spontaneous Breaking of (2+1)-dimensional Lorentz Symmetry by an antisymmetric tensor

Jia-Hui Huang, Guang-Zhou Guo, Hao-Yu Xie +2

One kind of spontaneous (2+1)-dimensional Lorentz symmetry breaking is discussed. The symmetry breaking pattern is $S O (2, 1) \to S O (1, 1)$ . Using the coset construction formal…

Renormalization of Feynman amplitudes on manifolds by spectral zeta regularization and blow-ups

Nguyen Viet Dang, Bin Zhang

Our goal in this paper is to present a generalization of the spectral zeta regularization for general Feynman amplitudes. Our method uses complex powers of elliptic operators but i…

Branching fraction measurement of $J / ψ \to K_{S} K_{L}$ and search for $J / ψ \to K_{S} K_{S}$

BESIII Collaboration, M. Ablikim, M. N. Achasov +441

Using a sample of $1.31 \times 1 0^{9}$ $J / ψ$ events collected with the BESIII detector at the BEPCII collider, we study the decays of $J / ψ \to K_{S} K_{L}$ and $K_{S} K_{S}$ . The br…

On bifurcation of eigenvalues along convex symplectic paths

Yinshan Chang, Yiming Long, Jian Wang

We consider a continuously differentiable curve $t \mapsto γ (t)$ in the space of $2 n \times 2 n$ real symplectic matrices, which is the solution of the following ODE: $\frac{\mathrm{d…

Search for the rare decays $J / ψ \to D^{0} e^{+} e^{-} + c . c .$ and $ψ (3686) \to D^{0} e^{+} e^{-} + c . c .$

M. Ablikim, M. N. Achasov, S. Ahmed +436

Using the data samples of $(1310.6 \pm 7.2) \times 1 0^{6}$ $J / ψ$ events and $(448.1 \pm 2.9) \times 1 0^{6}$ $ψ (3686)$ events collected with the BESIII detector, we search for the rare d…

Dynamics of social contagions with local trend imitation

Xuzhen Zhu, Wei Wang, Shimin Cai +1

Research on social contagion dynamics has not yet including a theoretical analysis of the ubiquitous local trend imitation (LTI) characteristic. We propose a social contagion model…
