Charm-Anticharm Asymmetries in Photoproduction from Heavy-Quark Recombination
Eric Braaten, Yu Jia, Thomas Mehen
The asymmetries between charm and anticharm mesons observed in fixed-target photoproduction experiments are an order of magnitude larger than the asymmetries predicted by conventio…
B Production Asymmetries in Perturbative QCD
Eric Braaten, Yu Jia, Thomas Mehen
This paper explores a new mechanism for B production in which a b quark combines with a light parton from the hard-scattering process before hadronizing into the B hadron. This rec…
The Dilute Bose-Einstein Condensate with Large Scattering Length
Eric Braaten, H. -W. Hammer, Thomas Mehen
We study a dilute Bose gas of atoms whose scattering length a is large compared to the range of their interaction. We calculate the energy density of the homogeneous Bose-Einstein…
Solution to the 3-Loop -Derivable Approximation for Massless Scalar Thermodynamics
Eric Braaten, Emmanuel Petitgirard
We develop a systematic method for solving the 3-loop -derivable approximation to the thermodynamics of the massless field theory. The method involves expanding sum-integr…
Solution to the 3-loop -derivable Approximation for Scalar Thermodynamics
Eric Braaten, Emmanuel Petitgirard
We solve the 3-loop -derivable approximation to the thermodynamics of the massless field theory by reducing it to a 1-parameter variational problem. The thermodynamic pote…
Three-body recombination into deep bound states in a Bose gas with large scattering length
Eric Braaten, H. -W. Hammer
An effective field theory for the three-body system with large scattering length a is applied to three-body recombination into deep bound states in a Bose gas. The recombination co…
