Higgs BOSON and Nonstability of electroweak vacuUM

The need to search for new physics associated with the problems of the standard model [1] leads to the need to use the appropriate theoretical apparatus such as the theory of D-branes [2, 3]. In this case, complex nonlinear equations describing processes at high energies and their solutions are replaced by considering vector bundles and by calculation of their topological invariants — analogs of solutions of nonlinear equations. Such topological invariants of type IIB superstring theory are the Ramon-Ramon (RR) charges described by K-theory [4]. Examples of calculating of the RR charges for several cases of spaces of extra dimensions are considered. The possibilities of embedding Calabi-Yau spaces suggest the phase transitions between different soliton states in vacuum, described by topological invariants. Such transitions are connected with the existence of a multiverse with different vacua. This explains the instability of the electroweak vacuum presented in Fig.1
