Three-state complex valued spins coupled to binary branched polymers in two-dimensional quantum gravity
NUCL PHYS B-PROC SUP 63 (1998) 754-756
Abstract:
A model of complex spins (corresponding to a non-minimal model in the language of CFT) coupled to the binary branched polymer sector of quantum gravity is considered. We show that this leads to new behaviour.Quantifying uncertainties in primordial nucleosynthesis without Monte Carlo simulations

Abstract:
We present a simple method for determining the (correlated) uncertainties of the light element abundances expected from big bang nucleosynthesis, which avoids the need for lengthy Monte Carlo simulations. Our approach helps to clarify the role of the different nuclear reactions contributing to a particular elemental abundance and makes it easy to implement energy-independent changes in the measured reaction rates. As an application, we demonstrate how this method simplifies the statistical estimation of the nucleon-to-photon ratio through comparison of the standard BBN predictions with the observationally inferred abundances.Quantifying uncertainties in primordial nucleosynthesis without Monte Carlo simulations
