Normalize by T ~ 100 GeV in SM is common (unique) area of triangle B.A.U. from Electroweak Baryogenesis? CPV Too Small in SM WMAP Why? Jarlskog Invariant in SM3 (need 3 generation in KM) masses too small !
Only fac. 30 in CPV per se B.A.U. from Electroweak Baryogenesis? CPV Too Small in SM WMAP If shift by One Generation in SM4(need 3 generation in KM) ~ 10+15 Gain Gain mostly in Large Yukawa Couplings !
Carena, Megevand, Quirós, Wagner, NPB’05 • Fermion • Couple Strongly to Higgs Can “Boil” Higgs Soup • mF/T Not small Cannot use above m/T expansion • Not too large Does not decouple too early Upshot: relativistic d.o.f. g* become g*(f), effective reheating by F decoupling around Tc Stronger Transition B.A.U. from Electroweak Baryogenesis? Order of Phase Transition Too much equlibration in SM washes away B.A. at high T Cubic term too small Extra Heavy Bosons (usual approach)

B.A.U. from Electroweak Baryogenesis? CPV Order of Phase Transition Can 4th Generation Restore Electroweak Baryogenesis ? Can we use this to Demand to see NP b → s CPV ?
V. Discussion and Conclusion • 4thgeneration not in such great conflict with EWPrT • Kribs, Plehn, Spannowsky, Tait, PRD’07 • Issue of “UV completion” for EWBG picture (vacuum stability) • Heavy 4th generation above 600 GeV (unitarity limit) • could lead to EWSB No Higgs ? Holdom, JHEP’06 • t’ & b’ can be discovered at LHC !
