SUMMARY:Electroweak phase transition in the U(1)'-extended MSSM\, NPAC
  (Nuclear/Particle/Astro/Cosmo) Forum\, Eibun Senaha\, National Centra
 l University\, Taiwan
DESCRIPTION:We discuss electroweak phase transition (EWPT) in the secl
 uded<br><br>
\nU(1)'-extended MSSM with/without CP violation.<br><br>

 \nUnlike the MSSM\, the EWPT can be strong first order without a light
  stop.<br><br>
\nIn such a case\, the singlet-like Higgs bosons and th
 e charged Higgs bosons<br><br>
\nplay an important role. It is found t
 hat at least two Higgs bosons should be<br><br>
\nless than 300 GeV fo
 r the strong first order phase transition.<br><br>
\nDepending on the 
 charged Higgs boson mass\, the lightest Higgs boson can be<br><br>
\na
 s large as 220 GeV. It is also found that the CP violating phase in th
 e Higgs sector<br><br>
\ndo not weaken the strength of the first order
  EWPT.<br><br>
