Introduction

 

In this seminar we highlight and discuss in detail recent results from the Large Hadron Collider, CERN. A special focus is placed on particularly exciting measurements and searches for new physics with a high physics impact.
 

Topics

We are open to any topics you propose, so if there is a measurement you always wanted to understand better, please go ahead and suggest it! Other possible topics for talks that we consider particularly interesting at the moment are (in no particular order):

  1. Excess in the diphoton invariant mass spectrum at 750 GeV in Run 2 (and why not in Run 1?) by ATLAS and CMS
  2. Excess in the diboson invariant mass spectrum at 2 TeV in Run 1 (and Run 2?) by ATLAS and CMS
  3. Excess in events with a same sign lepton pair + multiple b-quark jets (multi-top quark) by ATLAS in Run 1
  4. Measurement of the top quark mass at the LHC (direct or indirect) by ATLAS and CMS
  5. Excess of events with two leptons and two jets in search for right-handed massive neutrinos by CMS in Run 1
  6. Excess in the search for Higgs decays to a tau lepton and a muon by CMS and ATLAS in Run 1
  7. Excess of events with two leptons from Z->ll decays, jets, and missing transverse momentum (SUSY) by ATLAS and CMS in Run 1
  8. Direct measurement of the Yukawa coupling of the top quark using ttH events (ATLAS and CMS, "too strong")
  9. Indirect measurement of the Yukawa coupling of the top quark from a global fit (ATLAS and CMS, "too strong")
  10. Excess in search for Bs -> µµ decays by LHCb
  11. Excesses in Bs -> K*µµ, Bs -> phi µµ measurements (and global fit in effective field theory) by LHCb
  12. Lepton universality violation in B→D(*)+tau/B→D(*)+µ by LHCb, BaBar, and Belle
  13. Lepton universality violation in B→K+e/B→K+µ by LHCb
  14. Discovery of the pentaquark by LHCb
  15. Vub : Lambdab -> p mu nu
  16. CKM angle gamma: B± -> D0K±

Formalia

The seminar takes place on Tuesdays 16h00-17h00 (note we start at 16h00 sharp, not c.t.), first date 19.04.16. Registration through Übungsgruppenverwaltung.

Requirements

  • Independent literature research of the topic, in particular related publications. The talk supervisor gives a central publication as a starting point. Please contact him on time.
  • Logical outline and preparation of the talk
  • Dry-run talk with supervisor
  • 45 min talk (maximum), 15 min discussion
  • 6 ECTS credit points

Course of seminar:

  • 19. April 2016: First seminar meeting, organisatorial issues, choice of topics (if not yet happened), choice of talk dates
  • At the latest in week (n-3): discuss logical outline and a concept sketch of the talk with the supervisor. There is a possibility to discuss important physics question, for which we reserve about 1/2h
