In curved space time inside the shell of TeV black holes, many gluons and quarks produce due to Unruh effect, interact with each other and create Higgs boson. We study the Unruh effect and show that the inside state of the black hole for gluons and quarks can be represented by a maximally entangled two-mode squeezed state of inside and matter Hilbert spaces of black hole. We consider different channels for Higgs boson production inside the shell and outside the shell of mini black holes at LHC and obtain its cross section in each channel. Comparing the Higgs boson production outside and inside the shell ,we observe that at lower mass MBH < 4T eV and at higher mass MBH > 9T eV , the Higgs boson will not be produced outside the shell of black hole,However this particle can be produced inside the shell for 2.5T eV < MBH < 12.5T eV .Also comparing Higgs production via quark or gluon interaction we find that the outside the shell of black hole is able to produce a quark for 3T eV < MBH < 10T eV ; and eventually for MBH < 3T eV andMBH > 12.5T eV the black hole can only emit massless gluons.However inside the shell of black hole is able to produce a quark for 2.5T eV < MBH < 14T eV .Comparing these Higgs boson cross sections with Higgs boson cross sections in Perturbative Quantum Chromo Dynamics (P QCD), we find that the micro black hole can be a source for Higgs production at LHC. Finally we calculate the effects of Higgs boson radiation due to inside the shell and outside the shell of mini black holes on hadronic cross section at LHC. We observe that as the order of perturbation theory increases, this effect becomes systematically more effective, because at higher orders there exists more channels for Higgs production and their decay of Higgs into massive quark-anti quarks in our calculation. At smaller mass, (MBH < 2T eV ),the NNLO contribution is large while the cross sections at NLO and at LO are rising at MBH < 3T eV andMBH > 4T eV respectively and exhibit a turn-over at moderate values of black hole mass. The peak moves from about 5TeV (LO) to 2.5TeV (NNLO). These results are different from references due to effects of Higgs boson production and decay inside the event Horizon.It ′ s concluded that the processes of hadronization inside the event horizon of mini black holes is affected the hadronic cross section outside the event horizon and can be observed at LHC.
