DESCRIPTION:Nikita Blinov (SLAC)\nMany theories require augmenting the Sta
 ndard Model with additional scalar fields with large order one couplings. 
 We present a new solution to the hierarchy problem for these scalar fields
 . I will discuss Z2-symmetric theories where the Standard Model Higgs pote
 ntial has two vacua. The Z2 copy of the Higgs lives in the minimum far fro
 m the origin while our Higgs occupies the minimum near the origin of the p
 otential. This approach results in a theory with multiple light scalar fie
 lds but with only a single hierarchy problem\, since the bare mass is tied
  to the Higgs mass by a discrete symmetry. The new scalar does not have a 
 new hierarchy problem associated with it because its expectation value and
  mass are generated by dimensional transmutation of the scalar quartic cou
 pling. The location of the second Higgs minimum is not a free parameter\, 
 but is rather a function of the matter content of the theory. As a result\
 , these theories are extremely predictive. We develop this idea in the con
 text of a solution to the strong CP problem. We show this mechanism postdi
 cts the top Yukawa to be within 1σ of the currently measured value and pr
 edicts scalar color octets within reach of a future collider.
