Nucleon and nuclear structure through dilepton production
I. V. Anikin, N. Batzell, M. Boer +29
Transverse momentum distributions and generalized parton distributions provide a comprehensive framework for the three-dimensional imaging of the nucleon and the nucleus experiment…
Gluons and the quark sea at high energies: distributions, polarization, tomography
D. Boer, M. Diehl, R. Milner +186
This report is based on a ten-week program on "Gluons and the quark sea at high-energies", which took place at the Institute for Nuclear Theory in Seattle in Fall 2010. The princip…
Towards a fitting procedure for deeply virtual Compton scattering at next-to-leading order and beyond
K. Kumericki, D. Müller, K. Passek-Kumericki
Combining dispersion and operator product expansion techniques, we derive the conformal partial wave decomposition of the virtual Compton scattering amplitude in terms of complex c…
Long vs. short distance dispersive two-photon K_L \to μ^+ μ^- amplitude
J. O. Eeg, K. Kumericki, I. Picek
We report on the calculation of the two-loop electroweak, two-photon mediated short-distance dispersive K_L \to μ^+μ^- decay amplitude. QCD corrections change the sign of this co…
Nucleon strangeness as the response to a strangeness-sensitive probe in a class of hadron models
D. Klabucar, K. Kumericki, B. Melic +1
On top of its valence quarks, the full nucleon ground state may contain appreciable admixture of s-\bar{s} pairs already at small momentum transfers. This paper discusses strangene…
ePIC Early Science Report
D. Abbott, N. Abdelrahman, S. Abhijit +781
This Early Science Report from the ePIC Collaboration outlines the compelling physics program achievable during the first years of operation of the Electron-Ion Collider (EIC), pri…
Deeply virtual Compton scattering beyond next-to-leading order: the flavor singlet case
K. Kumericki, D. Müller, K. Passek-Kumericki +1
We study radiative corrections to deeply virtual Compton scattering in the kinematics of HERA collider experiments to next--to--leading and next--to--next--to--leading order. In th…
Soft gluon contributions to the B --> K eta' amplitude in a low energy bosonization model
J. O. Eeg, K. Kumericki, I. Picek
Intriguing B --> K eta' decays provide a unique opportunity to study a joining of two-gluon configurations arising from the penguin b --> sG and b --> sGG transitions, with those i…
Quark off-shell contributions to in a bound-state approach
D. Kekez, D. Klabucar, K. Kumericki +1
We present a new piece of evidence in favour of the importance of the quark off-shellness in the kaon. The matrix elements of the flavour-changing operators for comp…
The double radiative annihilation of the heavy-light fermion bound states
J. O. Eeg, K. Kumericki, I. Picek
We consider the double-radiative decays of heavy-light QED and QCD atoms, and . Especially, we take under scrutiny contributions coming…
On the instanton-induced portion of the nucleon strangeness
D. Klabucar, K. Kumericki, B. Melic +1
We calculate the instanton contribution to the proton strangeness in the MIT bag enriched by the presence of a dilute instanton liquid. The evaluation is based on expressing the nu…
On the dispersive two-photon K_L -> μ^+ μ^- amplitude
J. O. Eeg, K. Kumericki, I. Picek
We present a full account of the two-loop electroweak, two-photon mediated short-distance dispersive decay amplitude. QCD corrections change the sign of this ampl…
Bound-state effects in μ^+ e^- \to γγand \bar{B}^{0}_s \to γγdecays
J. O. Eeg, K. Kumericki, I. Picek
We demonstrate that in the double-radiative decays of heavy-light QED and QCD atoms, μ^{+} e^{-} \to γγand \bar{B}^{0}_{s} \to γγ, there is a contribution coming from operator…
On the Singlet Penguin in B --> K eta' decay
J. O. Eeg, K. Kumericki, I. Picek
New contributions to the short-distance b --> s eta' transition are considered. They correspond to the quark and gluon content of eta'. Although substantially larger than the refer…
On the Short Distance Part of the QCD Anomaly Contribution to the b --> s eta' Amplitude
J. O. Eeg, K. Kumericki, I. Picek
In addressing the B --> eta' K puzzle, there has been a considerable hope in the literature to resolve it by the QCD anomaly contribution to the b --> s eta' amplitude. This contri…
GPD sum rules: a tool to reveal the quark angular momentum
K. Kumericki, D. Mueller, K. Passek-Kumericki
In deeply virtual exclusive electroproduction to leading order accuracy one accesses generalized parton distributions on their cross-over trajectory. Combining Lorentz covariance a…
On Distinguishing Non-Standard Interactions from Radiative Corrections in Neutrino-Electron Scattering
K. Kumericki, I. Picek
We present a contribution of higher order to neutrino-electron scattering that is a charged-current counterpart of both the anomalous axial-vector triangle and possible non-standar…
