A Proof of the Explicit Minimal-basis Expansion of Tree Amplitudes in Gauge Field Theory
Yi-Xin Chen, Yi-Jian Du, Bo Feng
In last couple years, an important relation (BCJ relation) between color-ordered tree-level scattering amplitudes of gauge theory has inspired many studies. This relation implies t…
On tree amplitudes with gluons coupled to gravitons
Yi-Xin Chen, Yi-Jian Du, Bo Feng
In this paper, we study the tree amplitudes with gluons coupled to gravitons. We first study the relations among the mixed amplitudes. With BCFW on-shell recursion relation, we wil…
Black hole phase transitions in Hořava-Lifshitz gravity
Qiao-Jun Cao, Yi-Xin Chen, Kai-Nan Shao
We study black hole phase transitions in (deformed) Hořava-Lifshitz (H-L) gravity, including the charged black hole and KS black hole. Stability of black holes in H-L gravity and t…
Thermodynamical Metrics and Black Hole Phase Transitions
Haishan Liu, H. Lu, Mingxing Luo +1
An important phase transition in black hole thermodynamics is associated with the divergence of the specific heat with fixed charge and angular momenta, yet one can demonstrate tha…
Note on New KLT relations
Bo Feng, Song He, Rijun Huang +1
In this short note, we present two results about KLT relations discussed in recent several papers. Our first result is the re-derivation of Mason-Skinner MHV amplitude by applying…
Hidden Conformal Symmetry of Rotating Black Hole with four Charges
Kai-Nan Shao, Zhibai Zhang
Kerr/CFT correspondence exhibits many remarkable connections between the near horizon Kerr black hole and a CFT. Recently, a hidden conformal symmetry in the solution space of Kerr…
