Zero-mode product expansions and higher order couplings in gauge backgrounds
Masaki Honda, Tatsuo Kobayashi, Hajime Otsuka
We study a four-dimensional low-energy effective field theory derived from extra dimensional field theories with general gauge backgrounds. We find that products among fermionic ze…
heterotic standard model vacua in general Calabi-Yau compactifications
Hajime Otsuka, Kenta Takemoto
We study a direct flux breaking scenario in heterotic string theory on general Calabi-Yau threefolds. The direct flux breaking, corresponding to hypercharge flux breaking…
Affleck-Dine baryogenesis in the SUSY Dine-Fischler-Srednicki-Zhitnitsky axion model without R-parity
Kensuke Akita, Hajime Otsuka
We investigate the baryon asymmetry in the supersymmetry Dine-Fischler-Srednicki-Zhitnitsky axion model without R-parity. It turns out that the R-parity violating terms economicall…
SO(32) heterotic line bundle models
Hajime Otsuka
We search for the three-generation standard-like and/or Pati-Salam models from the heterotic string theory on smooth, quotient complete intersection Calabi-Yau threefolds…
