Localization of gauge fileds on brane via higgs mechanism

Speakers

  • Masaki KAWAGUCHI

Description

We study a localization mechanism of gauge fields on a 3-brane in Yang-Mills-Higgs models with a modified kinetic term of gauge fields in non-compact extra dimensions (D>4). The localization mechanism is carried out when the Higgs field locally condenses on the 3-brane. Hence, the Higgs mechanism yields, in addition to two conventional roles (spontaneous symmetry breaking of the gauge symmetry and generating mass for chiral fermions), a new important consequence, namely, localization of the gauge fields on a 3-brane. The lightest localized gauge field is massless (massive) if the Higgs field is neutral (charged) to the gauge field.
