An experimental program with high duty-cycle polarized and unpolarized positron beams at Jefferson Lab
Positron beams, both polarized and unpolarized, are identified as important ingredients for the experimental programs at the next generation of lepton accelerators. In the context of the hadronic physics progr...

Open AccessMass sum rules of the electron in quantum electrodynamics
Different decompositions of the nucleon mass, in terms of the masses and energies of the underlying constituents, have been proposed in the literature. We explore the corresponding sum rules in quantum electro...

Open AccessElectron-Ion Collider: The next QCD frontier
This White Paper presents the science case of an Electron-Ion Collider (EIC), focused on the structure and interactions of gluon-dominated matter, with the intent to articulate it to the broader nuclear scienc...

Open AccessTransverse-momentum-dependent parton distribution/fragmentation functions at an electron-ion collider
We present a summary of a recent workshop held at Duke University on Partonic Transverse Momentum in Hadrons: Quark Spin-Orbit Correlations and Quark-Gluon Interactions. The transverse-momentum-dependent parto...

Parity-violating spin asymmetries in polarized proton-proton scattering with hadronic final states
Longitudinal, parity-violating single spin asymmetries in proton-proton collisions for RHIC kinematics are considered. The focus of this study is on the production of a single jet as well as a hadron containin...

Overview of Recent Model Calculations of Single Spin Asymmetries
Over the past years a lot of progress has been made in the understanding of single spin asymmetries in hard scattering processes. We briefly review this subject, covering the non-vanishing of time-reversal odd...

Twist-3 single-spin asymmetries in semi-inclusive deep-inelastic scattering
The single-spin asymmetries for a longitudinally polarized lepton beam or a longitudinally polarized nucleon target in semi-inclusive deep-inelastic scattering are twist-3 observables. We study these asymmetri...

Detailed spectroscopy of superdeformed actinide nuclei
Progress in the experimental techniques used to investigate superdeformed fission isomers in the actinides allowed for detailed spectroscopic results of collective properties as well as for the identification ...

Introduction of a ketogenic diet in young infants
The ketogenic diet is a rational treatment for pyruvate dehydrogenase complex deficiency (McKusick 312170) and GLUT1 deficiency syndrome (McKusick 138140). An increasing number of patients are diagnosed in ear...

Nuclear structure of 181Hf studied in (n, γ) and (d, p) reactions
The level structure in 181Hf is studied by using (n, γ) and (d, p) reactions. Gamma-gamma coincidences permit an unambiguous placement of the majority of gamma transitions in the level scheme up to 1.8 MeV, while...

Supersymmetry in the spectra of complex atomic nuclei
Evidence is observed for the existence of supersymmetry from the study of the odd-odd nucleus 196Au using the 197Au( \(\vec d\) ...

Towards complete spectroscopy of 193Os
Strong evidence for the existence of supersymmetry in atomic nuclei has been found in the quartet of nuclei 194,195Pt, 195,196Au [1–3]. Our attention is now focused a second quartet of nuclei, that is 193,194Ir,

Dispersion relation formalism for virtual Compton scattering off the proton
We present in detail a dispersion relation formalism for virtual Compton scattering (VCS) off the proton from threshold into the Δ(1232)-resonance region. Such a formalism can be used as a tool to extract the ...

Hyperdeformation and clusterization in the actinide region
The 233U(d,pf)234U, and the 235U(d,pf)236U reactions have been studied with high energy resolution. The observed fission resonances were described as members of rotational bands with rotational parameters charact...

Experiments on the Magnetism of Sc Implanted into Metals
The study of dilute Sc impurities in either heavier d-transition metals or in alkali metal hosts is difficult due to their limited solubility; however, the large host-impurity mismatch in these systems makes them...

Detailed spectroscopy in the superdeformed second minimum of 240Pu
Spectroscopic studies in the superdeformed shape isomer of 240Pu using γ-spectroscopy, conversion electron spectroscopy and transmission resonance spectroscopy have been performed. In a high-resolution and high-e...

Semi-exclusive production of photons at HERA
We study the feasibility of measuring the semi-exclusive photon production \(\gamma + p \to \gamma + Y\) at HERA. The cross section of photons produced at large transverse momen...

Soft and hard Pomeron in the structure function of the proton at low x and low \(Q^2\)
We study inclusive electroproduction on the proton at low x and low \(Q^2\) using a soft and a hard Pomeron. The contribution of the soft Pomeron is based on the Stochastic Vacu...
