Bounds on large extra dimensions from the photon fusion process in SN1987A
V H Satheeshkumar1,2 and P K Suresh1
Show affiliationsThe constraint on the Arkani-Hamed, Dimopoulos and Dvali model of extra dimensions coming from photon annihilation into Kaluza–Klein gravitons in supernova cores is revisited. In the two-photon process, for a conservative choice of the core parameters, we obtain the bound on the fundamental Planck scale 
TeV. The combined rate of energy loss due to nucleon–nucleon bremsstrahlung and photon annihilation processes is rederived, and it shows that the combined bounds add only a second decimal place to M*. The present study may strengthen the results that are available in the current literature for the graviton emission from SN1987A, which puts very strong constraints on models with large extra dimensions for the case of n = 3.
