EXTRACTING MODEL PARAMETERS - ARE OUR
TECHNIQUES FIT FOR THE JOB?Patrick Meade

Outline
Number of ways to extract data from models have been/are being developed (more in Dirk’s talk)
Are these techniques robust? What models do we actually care about?
Models that have a point – can in principle talk about extracting parameters Old Standards (with some new twists perhaps) Newly Needed Ones
Models that don’t (at least from theory point of view) How quickly adaptable are the techniques
for new models?

Models that we care about?
How do we decide which to “fit”?

Fitting easy because motivated models have few parameters and
distinct signatures?

Other Models?
As model builders we have a lot of ways out so make sure techniques
for fitting are adaptive

New Models?
How do we think about fitting when new physics pops up? Effective lagrangians/Models
Again we need to be adaptive!

“Un”motivated Models
How do we characterize them? Effective lagrangians / form factors? Leftover questions from Matt’s talk
yesterday?

Thanks to the Organizers!(that came!)
Thanks especially to Tilman! Graham has your present but forgot to wrap it,
you’ll get it at lunch
