Lattice continuum-limit study of nucleon quasi-PDFs / Alexandrou, Constantia (Cyprus U. ; Cyprus Inst.) ; Cichy, Krzysztof (Mickiewicz U., Poznan) ; Constantinou, Martha (Temple U.) ; Green, Jeremy R. (CERN) ; Hadjiyiannakou, Kyriakos (Cyprus U. ; Cyprus Inst.) ; Jansen, Karl (DESY) ; Manigrasso, Floriano (Cyprus U. ; Humboldt U., Berlin ; Rome U., Tor Vergata) ; Scapellato, Aurora (Mickiewicz U., Poznan) ; Steffens, Fernanda (Bonn U.)
The quasi-PDF approach provides a path to computing parton distribution functions (PDFs) using lattice QCD. This approach requires matrix elements of a power-divergent operator in a nucleon at high momentum and one generically expects discretization effects starting at first order in the lattice spacing $a$.

Parton distribution functions of $\Delta^+$ on the lattice / Chai, Yahui (Peking U.) ; Li, Yuan (Peking U.) ; Xia, Shicheng (Peking U.) ; Alexandrou, Constantia (Cyprus Inst. ; Cyprus U.) ; Cichy, Krzysztof (Mickiewicz U., Poznan ; CERN) ; Constantinou, Martha (Temple U.) ; Feng, Xu (Peking U. ; Peking U., Beijing ; CICQM, Beijing ; Peking U., CHEP) ; Hadjiyiannakou, Kyriakos (Cyprus Inst.) ; Jansen, Karl (NIC, Zeuthen) ; Koutsou, Giannis (Cyprus Inst.) et al.
We present results for renormalized matrix elements related to the unpolarized quasi-distribution function of the $\Delta^+$ baryon making use of the large momentum effective theory. Two ensembles of $N_f=2+1+1$ twisted mass fermions with a clover term and pion masses of 250 MeV and 330 MeV are analyzed. [...]

Topological Susceptibility under Gradient Flow / Mejía-Díaz, Héctor (Mexico U., ICN) ; Bietenholz, Wolfgang (Mexico U., ICN) ; Cichy, Krzysztof (Frankfurt U. ; Mickiewicz U., Poznan) ; de Forcrand, Philippe (CERN ; Zurich, ETH) ; Dromard, Arthur (Regensburg U.) ; Gerber, Urs (IFM-UMSNH, Michoacan ; Mexico U., ICN) ; Sandoval, Ilya Orson (Mexico U., ICN)
We study the impact of the Gradient Flow on the topology in various models of lattice field theory. The topological susceptibility $\chi_{\rm t}$ is measured directly, and by the slab method, which is based on the topological content of sub-volumes ("slabs") and estimates $\chi_{\rm t}$ even when the system remains trapped in a fixed topological sector.

The Slab Method to Measure the Topological Susceptibility / Bietenholz, Wolfgang (Mexico U., ICN) ; Cichy, Krzysztof (Frankfurt U. ; Mickiewicz U., Poznan) ; de Forcrand, Philippe (CERN ; ETH, Zurich (main)) ; Dromard, Arthur (Regensburg U. ; Frankfurt U.) ; Gerber, Urs (IFM-UMSNH, Michoacan ; Mexico U., ICN)
In simulations of a model with topological sectors, algorithms which proceed in small update steps tend to get stuck in one sector, especially on fine lattices. This distorts the numerical results, in particular it is not straightforward to measure the topological susceptibility chi_t. [...]
