摘要：

In this paper we show that, analogously to how it occurs for black holes, there exist three well-defined laws for Lorentzian wormhole thermodynamics and that these laws are related to a thermal phantomlike radiation process coming from the wormhole throat. It is argued that the existence of wormholes could be manifested by means such as radiation. These results are obtained by analyzing the Hayward formalism of spherically symmetric solutions containing trapping horizons, the phenomenon of phantom accretion onto wormholes, and the development of phantom thermodynamics.
