Naturalness Workshop

[Joshua Rosaler]

Dear All,

My colleagues have graciously informed me that my last e-mail reached a
somewhat wider audience than anticipated. Here then, without further ado -
and with apologies for clogging all of your inboxes - is the advertisement
for our Aachen workshop on naturalness. Please note that the deadline for
applications is Jan. 31.

Very Best Wishes,
Josh


*Title: *Workshop on "Naturalness, Hierarchy, and Fine-Tuning"


*Workshop Description:* The requirement of naturalness has long served as
an influential constraint on model-building in elementary particle physics.
Yet there are many ways of understanding what, precisely, this requirement
amounts to, from restrictions on the amount of fine-tuning that a model can
exhibit, to prohibitions on sensitive dependence between physics at
different scales, to the requirement that dimensionless parameters defining
the Lagrangian of a theory all be of order one unless protected by a
symmetry. This workshop aims to clarify the relationships among these
concepts of naturalness and their connection to the hierarchy problem, as
well as to assess arguments for and against imposing various forms of
naturalness as a requirement on particle physics model-building. It
will bring together researchers in philosophy of physics and theoretical
particle physics whose expertise touches either directly on the subject
of naturalness or on closely related issues concerning effective field
theory, renormalization, and the physical interpretation of quantum field
theory.
