DESCRIPTION:Speakers: Monika Ghimiray ()\nIn this seminar\, I will present
  the analysis of same-sign WW and WZ boson production in association with 
 two jets in proton-proton collisions at a centre-of-mass energy of √s = 
 13.6 TeV. The analysis uses data collected by the CMS detector during 2022
 –2026\, corresponding to an integrated luminosity of 308 fb−1. The mea
 surements are performed in the leptonic decay channels W±Z → ℓ±νℓ
 ′+ℓ′− and W±W± → ℓ±νℓ′±ν\, where ℓ\, ℓ′ = e\, 
 μ. Both inclusive and differential fiducial cross sections are measured a
 s a function of several kinematic observables. In addition\, I will discus
 s the search for possible effects of physics beyond the Standard Model thr
 ough nomalous quartic gauge couplings (aQGCs)\, interpreted within the fra
 mework of the Standard Model Effective Field Theory (SMEFT) using dimensio
 n-8 oper-\nators. The sensitivity of different kinematic observables to th
 ese operators is investigated to identify the most sensitive variables and
  derive constraints on the corresponding Wilson coefficients. Finally\, th
 e dependence of these constraints on the EFT cutoff scale Λ is studied us
 ing the clipping technique.\n\nhttps://events.ncbj.gov.pl/event/509/contri
