SIDIS WG meeting

Tuesday 2 Apr 2024, 08:30 → 10:00 US/Eastern

Ralf Seidel presented his studies on radiative corrections.

- Based on unpolarized Djangoh simlation at 18 x 275 GeV

• Djangoh has ISR and FSR correctly included

- Effects are overall moderate (at the percent level) but can get significant for some kinemaic regions

• At moderate Q², ISR events can populate higher x values
• Effecs get stronger for higher Q² values
• Effects especially visible in the y distribution and at high P_T.

- Next step: Test impact on azimuthal asymmtries.

08:30 → 08:40 Announcements

Speakers: Charlotte Van Hulse, Stefan Diehl (JLU Giessen and UCONN)

08:40 → 09:00 ISR/FSR effects on SIDIS variables

Speaker: Ralf Seidl (RIKEN)
