Full positivity bounds for anomalous quartic gauge couplings in SMEFT
Fu-Ming Chang, Zhuo-Yan Chen, Shuang-Yong Zhou
Electroweak boson scattering at the LHC provides a crucial avenue for probing physics beyond the Standard Model, particularly regarding deviations in quartic gauge couplings. We de…

Boson star superradiance with spinning effects and in time domain
Fu-Ming Chang, He-Yu Gao, Víctor Jaramillo +2
Superradiance, the process by which waves are amplified through energy and angular momentum transfer, can also occur in horizonless objects like boson stars, due to both the real s…

Spinning -ball Superradiance in 3+1D
Guo-Dong Zhang, Fu-Ming Chang, Paul M. Saffin +2
Recently, it has been found that a -ball can amplify waves incident upon it, due to rotation in the internal space and the interaction of the two modes in the complex scalar fie…
