Diffractive Deep Inelastic Scattering in the Dipole Picture at Next-to-Leading Order
We calculate the contribution from the state production to the
diffractive cross sections in deep inelastic scattering at high energy. The
obtained cross section is finite by itself, and consists a part of the full
next-to-leading order result for the diffractive structure functions. Our
calculation for the diffractive structure functions is performed using exact
kinematics, under the shockwave approximation of the scattering process. Once
the calculation is completed, we show that the previously known behaviour at
the high- and large- regime can be extracted from our results by
taking the appropriate limits. Furthermore, we discuss the steps required to
obtain the complete next-to-leading order results for the structure functions
in the color glass condensate (CGC) formalism, and the application of these
results to phenomenology.Comment: DIS2023, talk by HH; 5 pages, 3 figure
Diffractive deep inelastic scattering at NLO in the dipole picture : The qÂŻqg contribution
Publisher Copyright: © 2022 authors.We calculate the contribution from the qq¯g state production to the diffractive cross sections in deep inelastic scattering at high energy. The obtained cross section is finite by itself and a part of the full next-to-leading order result for the diffractive structure functions. We perform the calculation in exact kinematics in the eikonal limit, and show that the previously known high-Q2 and large MX2 results for the structure functions can be extracted from our results in the appropriate limits. We furthermore discuss the steps required to obtain the full next-to-leading order results for the structure functions.Peer reviewe
Diffractive structure function in the dipole picture
We calculate the contribution from the component of a virtual
photon state to the small- diffractive cross section in deep inelastic
scattering in the saturation regime. The obtained cross section is finite by
itself and a part of the full next-to-leading order result. We perform the
calculation in exact kinematics in the eikonal limit, and show that the
previously known high virtuality and large invariant mass results
for the structure functions can be extracted. We furthermore discuss the steps
required to obtain the full next-to-leading order result.Comment: 6 pages, 1 figure. Presented by T.L. at "Diffraction and Low-x 2022,"

Length of Stay in Urban Areas of Circular Migrants from the Mountainous Areas in China
Currently, there is limited literature dealing with the length of stay of circular migrants in urban areas (LSCMU), although many studies have discussed the phenomenon of migration and the determinants of migration. This study attempts to fill this gap using survey data from the mountainous areas of Chongqing, Southwest China. From a comparative perspective, this study divided workers into two groups (a young group aged between 16 and 35 years and an old group aged between 36 and 65 years). The average LSCMU values for the young and old group were 225 days and 174 days, respectively. Two multi-regression models were used to estimate the determinants of LSCMU in the two groups. The results showed that LSCMU was closely related to individual factors in both groups, including gender, age and job training. Family and community factors, including household size, arable land per capita and the distance from market, had much weaker effects on the dependent variable, especially in the older group. It was noticeable that job training had significant positive effects on LSCMU in both groups; these findings have special implications for the urbanization process in China
