CosMIn: The Solution to the Cosmological Constant Problem

TL;DR

The paper proposes a novel approach to explain the tiny value of the cosmological constant by introducing a conserved number, CosMIn, which counts modes crossing the Hubble radius, unifying early and late universe phases.

Contribution

It introduces the dimensionless conserved number CosMIn, linking cosmic evolution phases and explaining the cosmological constant's observed value.

Findings

CosMIn is approximately 4π, matching theoretical expectations.

The approach reproduces the observed small value of mbda.

Provides a unified framework for early inflation and late acceleration.

Abstract

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.
