Reparametrization Invariance of Heavy Quark Effective Theory at O(1/m_Q^3)
Ch. Balzereit
We extend the investigation of the reparametrization invariance of Heavy Quark Effective Theory to O(1/m_Q^3). We show that to this order reparametrization invariance can only be m…
Spectator Effects in Heavy Quark Effective Theory at O(1/m_Q^3)
Christopher Balzereit
We complete the one loop renormalization of the HQET lagrangian at O(1/m_Q^3) including four fermion operators with two heavy and two light quark fields in the operator basis. It i…
Evolution of the Light Cone Distribution Function for a Heavy Quark
C. Balzereit, W. Kilian, T. Mannel
We compute the one-loop anomalous dimension for the light cone distribution function of a heavy quark and solve the corresponding evolution equation analytically. Some implications…
Renormalizing Heavy Quark Effective Theory at O(1/m_Q^3)
Christopher Balzereit
We present a calculation of the renormalized HQET Lagrangian at order O(1/m_Q^3) in the one particle sector. The anomalous dimensions of local operators and time ordered products o…
Heavy Quark Effective Field Theory at O(1/m_Q^2). II. QCD Corrections to the Currents
Christopher Balzereit, Thorsten Ohl
We present a calculation of the renormalized heavy-light and heavy-heavy currents in HQET at order O(1/m_Q^2).
Heavy Quark Effective Field Theory at O(1/m_Q^2). I. QCD Corrections to the Lagrangian
Christopher Balzereit, Thorsten Ohl
We present a new calculation of the renormalized HQET Lagrangian at order O(1/m_Q^2) and discuss the consequences of the BRST invariance of QCD and the reparameterization invarianc…
