The ΔΔ dibaryon resonance d⁎(2380) with (JP,I)=(3+,0) is studied theoretically on the basis of the 3-flavor lattice QCD simulation with heavy pion masses (mπ=679,841 and 1018 MeV). By using the HAL QCD method, the central Δ-Δ potential in the S37 channel

Identifying MaaS schemes that maximise economic benefits through an economic appraisal

European Journal of Transport and Infrastructure Research, 2022
Mobility-as-a-Service (MaaS) is a new concept of transport mobility where various mobility services such as public transport, taxi and sometimes rideshare services are offered as a bundle with subscription payment.

Quantum simulations of hadron dynamics in the Schwinger model using 112 qubits [PDF]

Physical Review D
Hadron wavepackets are prepared and time evolved in the Schwinger model using 112 qubits of IBM's 133-qubit Heron quantum computer ibm_torino. The initialization of the hadron wavepacket is performed in two steps. First, the vacuum is prepared across the

Total top-quark pair-production cross section at hadron colliders through O(αS(4)). [PDF]

Physical Review Letters, 2013
We compute the next-to-next-to-leading order (NNLO) quantum chromodynamics (QCD) correction to the total cross section for the reaction gg → tt + X. Together with the partonic channels we computed previously, the result derived in this Letter completes ...

Entropy in hadron-hadron collisions [PDF]

Physical Review D, 2000
We analyse the entropy properties in the proton-proton 1800 GeV events from the PYTHIA/JETSET Monte Carlo generator following a recent proposal concerning the measurement of entropy in multiparticle systems. The dependence on the number of bins and on the size of the phase-space region is investigated.

Resonances in heavy meson–heavy baryon coupled-channel interactions

European Physical Journal C: Particles and Fields, 2022
The interactions of $${\bar{D}}^{(*)} \Lambda _c - {\bar{D}}^{(*)}\Sigma _c^{(*)}$$ D ¯ ( ∗ ) Λ c - D ¯ ( ∗ ) Σ c ( ∗ ) are studied within the framework of a dynamical coupled-channel approach.

Hadron melting and QCD thermodynamics [PDF]

, 2013
We study in this paper mechanisms of hadron melting based on the spectral representation of hadronic quantum channels, and examine the hadron width dependence of the pressure.

Hadron multiplicities [PDF]

Physics Reports, 2001
We review results on hadron multiplicities in high energy particle collisions. Both theory and experiment are discussed. The general procedures used to describe particle multiplicity in Quantum Chromodynamics (QCD) are summarized. The QCD equations for the generating functions of the multiplicity distributions are presented both for fixed and running ...

On the scalar $$\varvec{\pi K}$$ π K form factor beyond the elastic region

European Physical Journal C: Particles and Fields, 2021
Pion–kaon ( $$\pi K$$ π K ) pairs occur frequently as final states in heavy-particle decays. A consistent treatment of $$\pi K$$ π K scattering and production amplitudes over a wide energy range is therefore mandatory for multiple applications: in ...
