Zero-bin subtraction and the q T spectrum beyond leading power (2024)
Journal Article
Ferrera, G., Ju, W., & Schönherr, M. (2024). Zero-bin subtraction and the q T spectrum beyond leading power. Journal of High Energy Physics, 2024(4), Article 5. https://doi.org/10.1007/jhep04%282024%29005

In this paper, we present an algorithm to construct the qT distribution at NLO accuracy to arbitrary power precision, including the assembly of suitable zero-bin subtrahends, in a mathematically well-defined way for a generic choice of rapidity-diver...

The qT and ∆ϕ spectra in W and Z production at the LHC at N3LL′+N2LO (2021)
Journal Article
Ju, W., & Schönherr, M. (2021). The qT and ∆ϕ spectra in W and Z production at the LHC at N3LL′+N2LO. Journal of High Energy Physics, 2021(10), https://doi.org/10.1007/jhep10%282021%29088

The production of weak gauge bosons, W± and Z, are at the core of the LHC precision measurement program. Their transverse momentum spectra as well as their pairwise ratios are key theoretical inputs to many high-precision analyses, ranging from the W...

Invariant-mass distribution of top-quark pairs and top-quark mass determination (2020)
Journal Article
Ju, W., Wang, G., Wang, X., Xu, X., Xu, Y., & Yang, L. L. (2020). Invariant-mass distribution of top-quark pairs and top-quark mass determination. Chinese Physics C, 44(9), Article 091001. https://doi.org/10.1088/1674-1137/44/9/091001

In this study, we investigate the invariant-mass distribution of top-quark pairs near the 2mt threshold, which strongly influences the determination of the top-quark mass mt. Higher-order non-relativistic corrections lead to large contributions, whic... Read More about Invariant-mass distribution of top-quark pairs and top-quark mass determination.

Top quark pair production near threshold: single/double distributions and mass determination (2020)
Journal Article
Ju, W., Wang, G., Wang, X., Xu, X., Xu, Y., & Yang, L. L. (2020). Top quark pair production near threshold: single/double distributions and mass determination. Journal of High Energy Physics, 2020(06), Article 158. https://doi.org/10.1007/jhep06%282020%29158

We investigate top quark pair production near the threshold where the pair invariant mass Mtt¯ approaches 2mt, which provides sensitive observables to extract the top quark mass mt. Using the effective field theory methods, we derive a factorization... Read More about Top quark pair production near threshold: single/double distributions and mass determination.
