First we consider the phaseless case, where all quark phases are identically set to zero so that Vφ1 = Vφ2 = I .
A Scaling Law for Quark Masses and the CKM matrix
One sees that there is a local minimum between the two extreme values (Φµ = 0, π), which are tested at LEP searches (µ > 0, µ < 0), but also that it is not so deep as to raise doubts on the exhaustiveness of “phaseless” searches.
Summary of the SUSY Working Group of the 1999 Les Houches Workshop
Stable optimizationless recovery from phaseless linear measurements.
Solving Quadratic Equations via PhaseLift when There Are About As Many Equations As Unknowns
We then discuss how the constrained path and phaseless approximations can be imposed to remove the sign and phase problems in our method.
Finite-Temperature Auxiliary-Field Quantum Monte Carlo for Bose-Fermi Mixtures
We also outline the implementation of the constrained path and phaseless approximations, which can respectively control the sign and phase problems.
