A muon collider would enable the big jump ahead in energy reach that is needed for a
fruitful exploration of fundamental interactions. The challenges of producing muon collisions …

The H1 Collaboration reports the first measurement of the 1-jettiness event shape
observable τ 1 b in neutral-current deep-inelastic electron-proton scattering (DIS). The …

Abstract For High Energy Physics (HEP) experiments, such as the Large Hadron Collider
(LHC) experiments, the calorimeter is a key detector to measure the energy of particles …

The Breit frame provides a natural frame to analyze lepton–proton scattering events. In this
reference frame, the parton model hard interactions between a quark and an exchanged …

The explicit expression for the R-ratio of electron–positron annihilation into hadrons, which
properly accounts for all the effects due to continuation of the spacelike perturbative results …

The renormalization group relations for the higher-order hadronic vacuum polarization
function perturbative expansion coefficients are studied. The folded recurrent and unfolded …

Abstract We update the Standard Model (SM) predictions for the branching ratios of the rare
top-quark decays t→ cg (g), and evaluate the maximum rates that can be reached in the …

Thallium-1223, a superconductor with high critical temperature (T c∼ 120 K) and high
irreversibility line is a promising alternative to copper layers as a low surface impedance …

Recently proposed Future Circular Collider based muon-proton colliders will allow
investigating lepton-hadron interactions at the highest center-of-mass energy. In this study …
