Dear colleagues,

here is a summary of the bullet points for the Flavor Group (not including overlap with other groups like top FCNCs):

Low Energy flavor and CP violation observables narrow the parameter space of various 
models of New Physics at the TeV scale: New physics has to have either a non-trivial flavor 
structure (i.e. not introduce flavor breaking wildly different than the Yukawa couplings) or be 
flavor blind.

This flavor structure can be tested at high energy:
- studies generally require more statistics than just discovery of new particles because in 
most cases the FV modes are subleading (but there are a few cases which there can still 
be O(1) effects)
- high energy probes provide complementary information to low energy measurements
- leptonic machines, except >= 1TeV colliders not likely to be relevant for quark flavor violation (given current LHC results)
but still important for precision flavor studies if lepton partners (e.g. sleptons) found in the next run of the LHC


Possible story:

A discovery of a "stop" below a TeV decaying mostly to 3rd generation and 
few hundred GeV light "chargino" in the first 14TeV LHC run. With no other squarks in sight the 
question of the flavor structure become very relevant. Combined investigation of charm observables 
and b physics observables at the LHCb upgrade and BelleII together with probing subleading flavor 
violating decays of the newly found stop at the HL LHC narrow down the main characteristics of the flavor 
structure of the discovered squark sector. Further discovery of other squarks at the end of the HL LHC or 
HE LHC upgrade confirm the pictures. Finally precision study of the light stop at a HE e+e- narrows down 
some of the mixing parameters.

regards,

Marina,
Soeren
and Michele
