The LHC offers rich opportunities to probe the core of QCD related questions, by studying minimum bias events, double parton interactions, small-x and diffractive scattering, as well as correlations in hadronisation processes. This contribution summarises recent achievements on those topics from the ATLAS Collaboration at the LHC collider. preprint CC-BY-4.0 https://creativecommons.org/licenses/by/4.0/ preprint CERN 2025 PROC CERN CDS-Invenio WebSubmit For annual report SzGeCERN Particle Physics - Experiment SzGeCERN Physics CERN LHC CERN ATLAS CERN Soft QCD CERN Double parton scattering CERN Same sign W pairs CERN Strange hadrons CERN Underlying event CERN Double diffraction CERN Exclusive central production CERN Ordered hadron chains CERN Helical QCD string CERN QCD CERN INTNOTE PRIVATLAS INTNOTEATLASPUBL PREPRINT CERN LHC ATLAS PH-EP ATLAS Collaboration C25-08-25.1 http://cds.cern.ch/record/2949145 Original Communication (restricted to ATLAS) 2803984 1226354 http://cds.cern.ch/record/2951396/files/ATL-PHYS-PROC-2025-129.pdf Stamped by WebSubmit: 16/12/2025 djama@cppm.in2p3.fr n 202570 91 2939468 madison20250825 PUBLIC 000788922CER INTNOTEATLASPUBL ConferencePaper PREPRINT
