Nonlinear Dynamics of Rapidly Driven Systems
Afshin Besharat, Alexander A. Penin
We consider systems characterized by the presence of a rapidly oscillating force. A general method is presented for the construction of the effective action governing the large-sca…
High-Energy Evolution of Power-Suppressed Amplitudes
Maximilian Delto, Alexander Penin, Lorenzo Tancredi
We present a new class of evolution equations which govern the high-energy behavior of power-suppressed scattering amplitudes. The equations can be viewed as a renormalization grou…
Dynamical Confinement and Magnetic Traps for Charges and Spins
Afshin Besharat, Alexander A. Penin
We use the effective field theory approach to systematically study the dynamics of classical and quantum systems in an oscillating magnetic field. We find that the fast field oscil…
Light quark mediated Higgs boson production in association with a jet at the next-to-next-leading order and beyond
Tao Liu, Alexander A. Penin, Abdur Rehman
We study the light quark effect on the Higgs boson production in association with a jet at the LHC in the intermediate transverse momentum region between the quark and the Higgs bo…
Bottomonium Hyperfine Splitting on the Lattice and in the Continuum
M. Baker, A. A. Penin, D. Seidel +1
We revise the analysis of the bottomonium hyperfine splitting within the lattice nonrelativistic QCD. The Wilson coefficients of the radiatively improved lattice action are evaluat…
Hyperfine splitting in positronium to : one-photon annihilation contribution
Marc Baker, Peter Marquard, Alexander Penin +2
We present the complete result for the one-photon annihilation contribution to the hyperfine splitting of the ground state energy levels in positronium. Numerica…
