CosMIn: The Solution to the Cosmological Constant Problem
  The current acceleration of the universe can be modeled in terms of a
cosmological constant. We show that the extremely small value of \Lambda L_P^2
~ 3.4 x 10^{-122}, the holy grail of theoretical physics, can be understood in
terms of a new, dimensionless, conserved number CosMIn (N), which counts the
number of modes crossing the Hubble radius during the three phases of evolution
of the universe. Theoretical considerations suggest that N ~ 4\pi. This single
postulate leads us to the correct, observed numerical value of the cosmological
constant! This approach also provides a unified picture of cosmic evolution
relating the early inflationary phase to the late-time accelerating phase.
