[phys4phys] [institut] Laboratory for High-Energy Physics Seminar, 6th March

[Ema Maričić]

Dear colleagues,

You are cordially invited to the Laboratory for High-Energy Physics 
seminar, which will be held on 6 March (Friday) at 14:00 CET. We will 
have a seminar by Dr. Alberto Carnelli (French National Centre for 
Scientific Research), in the library reading room "Dr Dragan Popović" of 
the Institute of Physics Belgrade. Title and abstract follow.

Vector boson scattering at the LHC

The seminar provides an overview of diboson production measurements at 
the Large Hadron Collider (LHC), with a focus on results from the ATLAS 
experiment obtained during Run 2 data-taking and offering a look at 
future developments. Diboson processes involve the production of two 
electroweak gauge bosons (WW, WZ, ZZ) and are essential for testing the 
predictions of the Standard Model, particularly the structure of 
electroweak interactions and gauge boson couplings. In the talk we will 
distinguish between inclusive diboson production and vector boson 
scattering (VBS), the latter being a rarer process where two bosons are 
produced alongside forward jets and is especially sensitive to new 
physics effects. Measurements of cross sections, differential 
distributions, and polarization states are discussed, along with 
interpretations using Effective Field Theory (EFT) to constrain 
anomalous triple and quartic gauge couplings. Recent results will be 
presented on the observation of electroweak diboson production in 
several channels (such as same-sign WW, WZ, and ZZ with jets) and 
emerging studies of boson polarization, which probe the electroweak 
symmetry breaking mechanism.

Kind regards,
