David Affiliation: National Chiao-Tung University Email address: dlin1971@gmail.com Title: Study of the Higgs-Yukawa Theory at the Strong-Yukawa Regime Authors: John Bulava, Philipp Gerhold, George W.-S. Hou, Karl Jansen, C.-J. David Lin, Kei-Ichi Nagai, Attila Nagy, Kenji Ogawa, Brian Smigielski Type: Parallel Session: Applications beyond QCD Abstract: We present an on-going project on the Higgs-Yukawa theory in the regime of large bare Yukawa coupling. We use the overlap fermion and the pHMC algorithm in this work. Our preliminary study shows that there exists a symmetric phase (vanishing scalar vacuum expectation value) in this regime. We also comment on the investigation of the spectrum. talk at Lattice 2011 Remote Talk tomorrow
