Implementation of Maxwell's equations in the reconstruction of the magnetic field in the $g-2$ storage ring / Bodwin, Geoffrey T. (Argonne) ; Chung, Hee Sok (Argonne ; Munich, Tech. U. ; CERN) ; Repond, José (Argonne)
We present a method for implementing the constraints that are implied by Maxwell's equations in fits to measurements of the magnetic field in the muon storage ring of the $g-2$ experiment. The method that we use makes use of toroidal-harmonic solutions of Laplace's equation. [...]

Higgs-boson decays to a vector quarkonium plus a photon revisited / Bodwin, Geoffrey T. (Argonne) ; Chung, Hee Sok (CERN) ; Ee, June-Haak (Korea U.) ; Lee, Jungil (Korea U.)
In this addendum to Phys.\ Rev.\ D {\bf 95}, 054018 (2017) we recompute the rates for the decays of the Higgs boson to a vector quarkonium plus a photon, where the vector quarkonium is $J/\psi$, $\Upsilon(1S)$, $\Upsilon(2S)$, or $\Upsilon(3S)$. We correct an error in the Abel-Pad\'e summation formula that was used to carry out the evolution of the quarkonium light-cone distribution amplitude in Phys.\ Rev.\ D {\bf 95}, 054018 (2017). [...]

$Z$-boson decays to a vector quarkonium plus a photon / Bodwin, Geoffrey T. (Argonne) ; Chung, Hee Sok (CERN) ; Ee, June-Haak (Korea U.) ; Lee, Jungil (Korea U.)
We compute the decay rates for the processes $Z\to V+\gamma$, where $Z$ is the $Z$ boson, $\gamma$ is the photon, and $V$ is one of the vector quarkonia $J/\psi$ or $\Upsilon(nS)$, with $n=1$, $2$, or $3$. Our computations include corrections through relative orders $\alpha_s$ and $v^2$ and resummations of logarithms of $m_Z^2/m_Q^2$, to all orders in $\alpha_s$, at NLL accuracy. [...]

Fragmentation contributions to hadroproduction of prompt $J/\psi$, $\chi_{cJ}$, and $\psi(2S)$ states / Chung, Hee Sok (CERN)
We compute leading-power fragmentation corrections to hadroproduction of charmonium states J/ψ, χcJ , and ψ(2S) in the nonrelativistic QCD factorization formalism. We include fragmentation functions through order α 2 s and parton production cross sections through order α 3 s . [...]

Measuring the Higgs-charm coupling with heavy quarkonia / Chung, Hee Sok (CERN)
We present a calculation of the Higgs boson decay into a quarkonium plus a photon and show that the branching ratio is sensitive to both the magnitude and sign of the Higgs-heavy quark coupling. Our numerical results include relativistic corrections, as well as logarithms of the Higgs mass divided by the heavy quark mass resummed to all orders in αs , which is carried out in the next-to-leading logarithmic accuracy. [...]

Higgs-Stoponium Mixing Near the Stop-Antistop Threshold / Bodwin, Geoffrey T. (Argonne) ; Chung, Hee Sok (Argonne ; CERN) ; Wagner, Carlos E. M. (Argonne ; Chicago U., EFI)
Supersymmetric extensions of the standard model contain additional heavy neutral Higgs bosons that are coupled to heavy scalar top quarks (stops). This system exhibits interesting field theoretic phenomena when the Higgs mass is close to the stop-antistop production threshold. [...]

New approach to the resummation of logarithms in Higgs-boson decays to a vector quarkonium plus a photon / Bodwin, Geoffrey T. (Argonne) ; Chung, Hee Sok (CERN) ; Ee, June-Haak (Korea U.) ; Lee, Jungil (Korea U.)
We present a calculation of the rates for Higgs-boson decays to a vector heavy-quarkonium state plus a photon, where the heavy quarkonium states are the J/psi and the Upsilon(nS) states, with n=1, 2, or 3. The calculation is carried out in the light-cone formalism, combined with nonrelativistic QCD factorization, and is accurate at leading order in m_Q^2/m_H^2, where m_Q is the heavy-quark mass and m_H is the Higgs-boson mass.
