A factorization method is introduced to properly supplement the soft-gluon (threshold) resummation contribution from parton distribution functions to the resummed results obtained by the Collins-Soper-Sterman resummation approach. We find that the impact of the threshold-resummation improved PDFs is comparable to the resummation effect of the partonic matrix element and can even predominate in high invariant mass regions. Moreover, the loop-induced gluon-gluon fusion channel in the type-I two-Higgs-doublet model is considered in our calculations. The numerical results show that the electroweak production via quark-antiquark annihilation dominates over the gluon-initiated QCD production by <jats:inline-formula> <jats:tex-math><?CDATA $ 1 \sim 2$?></jats:tex-math> <jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="cpc_45_12_123102_M2.jpg" xlink:type="simple" /> </jats:inline-formula> orders of magnitude. </jats:p>

<jats:title>Abstract</jats:title> <jats:p>We present the analytic calculation of two-loop master integrals that are relevant for <jats:italic>tW</jats:italic> production at hadron colliders. We focus on the integral families with only one massive propagator. After selecting a canonical basis, the differential equations for the master integrals can be transformed into the <jats:italic>d</jats:italic> ln form. The boundaries are determined by simple direct integrations or regularity conditions at kinematic points without physical singularities. The analytical results in this work are expressed in terms of multiple polylogarithms, and have been checked via numerical computations. </jats:p>

<jats:title>Abstract</jats:title> <jats:p>We perform a systematic study on the effect of non-uniform track efficiency correction in higher-order cumulant analysis in heavy-ion collisions. Through analytical derivation, we find that the true values of cumulants can be successfully reproduced by the efficiency correction with an average of the realistic detector efficiency for particles with the same charges within each single phase space. The theoretical conclusions are supported by a toy model simulation by tuning the non-uniformity of the efficiency employed in the track-by-track efficiency correction method. The valid averaged efficiency is found to suppress the statistical uncertainties of the reproduced cumulants dramatically. Thus, usage of the averaged efficiency requires a careful study of phase space dependence. This study is important for carrying out precision measurements of higher-order cumulants in heavy-ion collision experiments at present and in future.</jats:p>

<jats:title>Abstract</jats:title> <jats:p>The flux-weighted average cross sections of <jats:sup>nat</jats:sup>Cd(γ, <jats:italic>xn</jats:italic>)<jats:sup>115g,m,111m,109,107,105,104</jats:sup>Cd and <jats:sup>nat</jats:sup>Cd(γ, <jats:italic>x</jats:italic>)<jats:sup>113g,112,111g,110m</jats:sup>Ag reactions were measured at the bremsstrahlung end-point energies of 50 and 60 MeV. The activation and off-line γ-ray spectrometric technique was carried out using the 100 MeV electron linear accelerator at the Pohang Accelerator Laboratory, Korea. The <jats:sup>nat</jats:sup>Cd(γ, <jats:italic>xn</jats:italic>) reaction cross sections as a function of photon energy were theoretically calculated using the TALYS-1.95 and the EMPIRE-3.2 Malta codes. Then, the flux-weighted average cross sections were obtained from the theoretical values of mono-energetic photons. These values were compared with the flux-weighted values from the present study and were found to be in general agreement. The measured experimental reaction cross-sections and integral yields were described for cadmium and silver isotopes in the <jats:sup>nat</jats:sup>Cd(γ, <jats:italic>xn</jats:italic>)<jats:sup>115g,m,111m,109,107,105,104</jats:sup>Cd and <jats:sup>nat</jats:sup>Cd(γ, <jats:italic>x</jats:italic>)<jats:sup>113g,112,111g,110m</jats:sup>Ag reactions. The isomeric yield ratio (IR) of <jats:sup>115g,m</jats:sup>Cd in the <jats:sup>nat</jats:sup>Cd(γ, <jats:italic>xn</jats:italic>) reaction was determined for the two bremsstrahlung end-point energies. The measured isomeric yield ratios of <jats:sup>115g,m</jats:sup>Cd in the <jats:sup>nat</jats:sup>Cd(γ, <jats:italic>xn</jats:italic>) reaction were also compared with the theoretical values of the nuclear model codes and previously published literature data of the <jats:sup>116</jats:sup>Cd(γ, <jats:italic>n</jats:italic>) and <jats:sup>116</jats:sup>Cd(<jats:italic>n</jats:italic>, 2<jats:italic>n</jats:italic>) reactions. It was found that the IR value increases with increasing projectile energy, which demonstrates the characteristic of excitation energy. However, the higher IR value of <jats:sup>115g,m</jats:sup>Cd in the <jats:sup>116</jats:sup>Cd(<jats:italic>n</jats:italic>, 2<jats:italic>n</jats:italic>) reaction compared to that in the <jats:sup>116</jats:sup>Cd(γ, <jats:italic>n</jats:italic>) reaction indicates the role of compound nuclear spin alongside excitation energy. </jats:p>

<jats:title>Abstract</jats:title> <jats:p>Hundreds of thousands of experimental data sets of nuclear reactions have been systematically collected, and their number is still growing rapidly. The data and their correlations compose a complex system, which underpins nuclear science and technology. We model the nuclear reaction data as weighted evolving networks for the purpose of data verification and validation. The networks are employed to study the growing cross-section data of a neutron induced threshold reaction (<jats:italic>n</jats:italic>,2<jats:italic>n</jats:italic>) and photoneutron reaction. In the networks, the nodes are the historical data, and the weights of the links are the relative deviation between the data points. It is found that the networks exhibit small-world behavior, and their discovery processes are well described by the Heaps law. What makes the networks novel is the mapping relation between the network properties and the salient features of the database: the Heaps exponent corresponds to the exploration efficiency of the specific data set, the distribution of the edge-weights corresponds to the global uncertainty of the data set, and the mean node weight corresponds to the uncertainty of the individual data point. This new perspective to understand the database will be helpful for nuclear data analysis and compilation. </jats:p>
