1 Report from Physics WG

2 WG Activities 2

3 Subgroup Activities 1. News from Higgs/EW WG since Last Genera ILD Phone Mtg. (Graham, Junping) new anaysis (fu sim): ZZ-fusion as we as update on ZH for anomaous HVV 250 GeV (Tomohisa, Apri 5 S&A) γh 250 GeV (Yumi Aoki, to be reported) Update on H WW* (Mia, Apri 5 S&A) Update on H μμ (Shin-ichi, May 24 S&A) Update on mh using H bb (Aiakbar Ebrahimi, Apri 5 S&A) update on Poarimetry study (Robert) pubications: Higgs sef-couping anayses; Higgs CP using H τ τ; ongoing

4 Subgroup Activities (continued) 2. News from BSM WG since Last Genera ILD Phone Mtg. (Mikae, Jackie) (1) Light Higgsinos (Jackie Yan, et a) anaysis in the fina stage (to be reported soon) (2) SUSY parameter extraction from resuts of (1) (Suvi-Leena Lehtinen, H. Baer et a.) - cose to fina starting STC4 (May 10 S&A) Paper for (1) and (2) in preparation (3) Search for a Higgs-ike scaar using Zh with Z->μμ (Yan Wang, May 24 S&A)

5 Subgroup Activities (continued) 3. Report from Top/QCD WG (Roman, Hitoshi) Top/QCD - Overview Topic Group Comment ee->tt Fu eptonic, Matrix eement LAL/Tohoku Ongoing anaysis ee->bb LAL Ongoing anaysis, paper and PhD thesis in 2017 Top mass, ee->ttγ IFIC Ongoing anaysis Lightweight organisation Mai and persona Communication Actors know each other Reguar reports at s/w and Anaysis meetings Top mass Threshod, interpretation ee->tt Anomaous coupings using EFT MPP-MPG IFIC Ongoing anaysis Ongoing anaysis Top CPV coupings IFIC/LAL/RWTH Paper in preparation ee->tt, continuum Fuy hadronic??? Under discussion: LAL internship and UCL London Jet agorithms IFIC Standing item with severa appications QCD e.g. apha_s??? Open topic t->ch Warsaw Ongoing anaysis t->cγ MPP Ongoing anaysis Good communication with theory and instrumentation groups Members of ILD Top/QCD pay visibe roes in promoting Top/QCD topics in severa instances Top/QCD studies in ILD are backbone when demonstrating LC physics potentia (w.r.t. Top/QCD) Next major event: Top@LC17, 7-9 June 2017 at CERN Mainy organized by Phiipp Rooff Roman Pösch ILD Meeting 24/5/17 1

6 Top/QCD - Recent news and future events ee->bb anaysis reaches maturity and work on interpretation has started About to become benchmark anaysis in ILD Matrix eement anaysis Further visit of Yo to LAL to condense ideas and recent findings into resuts for top@lc17 and AWLC Advanced draft on CPV paper by Marce (IFIC, LAL + Bernreuther) Top mass measurement using ee->ttγ (IFIC) Issues with photon definition in generator and photon measurement in generator Comprehensive anaysis of top coupings in EFT Framework F. Simon continued on extraction of top mass from threshod (rather phenomenoogie) No news on anomaous top decays Anayses may rather be CLIC oriented QCD sector of working group Jet studies at Vaencia ( standing item ) Sti no group working on apha_s Need to remind/assure community that GigaZ is sti part of ILC program A anayses/studies wi be presented at top@lc17 and (at east partiay) at AWLC17

7 Schedued Conference Taks 1. EPS (Juy 5-12) taks Precision Higgs Measurements at the 250 GeV ILC: in ight of staging ora : Tim Barkow The Potentia of the ILC for Discovering New Partices: ICFA support document ora : Jenny List Toward Precision Top Quark Measurements in e+e- coisions: ILC/CLIC combined ora : Naomi van der Kok Precision EW (inc. TGC, etc.) poster : Robert Kar Semi-private taks Higgs: HVV ora : Tomohisa Ogawa Higgsinos ora : Suvi-Leena Lehtinen e+e- bb poster : Sviatosav Biokin 2. APS DPF (1st week of Aug.) Essentiay the same abstracts have been submitted as EPS. Speaker seection on going.

8 Schedued Conference Taks 1. LCWS 2017 taks in Tuesday afternoon penary physics session: ILD is requested to offer a speaker for New ILC/ SiD resuts on BSM and bottom and top quark physics.

9 Staging Discussion LCC Physics WG is preparing a document on EFT interpretation of Higgs & TGC 250 GeV => neary finished sti ooking for exampe BSM points (!) with >3% deviations in Higgs coupings Parameter Group wi meet this or next week

10 Physics focus schedue May 6: Genera ILD meeting (today) Jun 7: Higgs/EW (Frank) Jun 21: AWLC17 rehearsa (Jenny) further schedue to be announced after physics conveners meeting on June 14 aso avaiabe on Conveners ML: Use this maiing ist to send your tak request.
