Wriggling Microtubules Explain Coupling Active Defects Curvature
2017/10/26
Imagine a tiny donut-shaped droplet, covered with wriggling worms. The worms are packed so tightly together that they must locally line up with respect to each other. In this situation, we would say t...
Meson Loops and the gD*D\pi Coupling
Effective Lagrangian Chiral symmetry Hadronic loop model Heavy form factor QCD sum rule
2010/10/13
The D¤Dp form factor is evaluated at low and moderate Q2 in a hadronic loop model, for off-shell D mesons. The results contain arbitrary constants, which are fixed so as to match a previous QCD sum ru...
On the One-loop Yukowa Coupling Beta Function to Order Yg2 in a General a Gauge and Its Gauge Indepence
one-loop Yukawa Gauge Indepence Order Yg2
2010/4/19
We present the calculation of the one-loop Yukawa coupling beta function to order Yg2 in a general a gauge, where Y and g are Yukawa and gauge couplings. We show explicitly how the gauge parameter a c...
