Higgs Potential and Naturalness After the Higgs Discovery by Yuta Hamada

By Yuta Hamada

This thesis specializes in the theoretical starting place of the normal version legitimate as much as the Planck scale, according to the present experimental proof from the massive Hadron Collider. The thesis comprises subject matters: (1) to open up a brand new window of the Higgs inflation state of affairs, and (2) to discover a brand new strategy to the naturalness challenge in particle physics. 

In the 1st region, at the Higgs inflation situation, the writer effectively improves a wide worth challenge on a coupling consistent correct to the Higgs mass within the general version, within which the coupling worth of the order of 105 predicted in a traditional state of affairs is decreased to the order of 10. This end result makes the Higgs inflation extra appealing as the small price of coupling is traditional within the context of ultraviolet final touch akin to string concept. within the moment quarter, the writer offers a brand new resolution to the naturalness challenge, of why the cosmological consistent and the Higgs mass are tremendous small in comparison with the Planck scale. in accordance with the infant universe idea initially proposed by means of Coleman, the smallness of these amounts is effectively defined with out introducing any extra new debris proper on the TeV power scale.
