318. S3 as a modular symmetry: consequences in the quark and Higgs sectors

Myriam Mondragon (Universidad Nacional Autonoma de Mexico UNAM)

Higgs and EW Physics

Plenary

An open problem in the Standard Model relates to the origin of the mass hierarchy among fermions, and its mixing. Different alternatives have been proposed by adding extra symmetries that relate the three generations of fermions and by extending the Higgs sector. In particular, it has been shown that the S3 symmetry has given good results if two extra Higgs doublets are added to the Standard...

130. Nucleon Structure Functions at Large x

Prof. Sebastian Kuhn (ODU)

1/10/23, 11:20 AM

Plenary

Parton distribution functions at high momentum fraction x continue to be of high interest. On the one hand, they can test predictions from models, effective theories and pQCD in the valence region, where most of the nucleon momentum is carried by a single quark. On the other hand, PDFs at high x and moderate Q2 are linked, via DGLAP evolution, to moderate x and high Q2 kinematics relevant for...

341. QED Corrections to Azimuthal Asymmetries of SIDIS Cross sections

Andrei Afanasev

1/10/23, 11:55 AM

Plenary

We analyze an impact of QED corrections on observables of semi-inclusive deep-inelastic scattering (SIDIS) of electrons and muons on a proton target. It is shown that both the radiative effects and two-photon exchange generate new azimuthal dependent-terms and corresponding 𝑐𝑜𝑠(𝑛𝜙) moments. A quark-diquark model of a nucleon was used in the calculations of two-photon effects which appear to be...
