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. Search for new resonances in diboson invariant mass spectrum by ATLAS (2.5 sigma)
  2. W mass measurement by ATLAS (first W mass result from LHC) and its relevance
  3. Measurement of Hbb coupling in Zh and Vh at ATLAS (both channels low)
  4. Searches for new resonances using dijets by ATLAS (or CMS) at low and high mass (strong sensitivity if New Physics couples to hadrons)
  5. Search for new resonances decaying into a lepton and missing transverse momentum with ATLAS (strong sensitivity to W-like new particles)
  6. Searches for Dark Matter produced in association with a Higgs boson by ATLAS (complementarity between h --> bb and h --> yy channels)
  7. Stop 0 lepton search with CMS (some excess)
  8. Direct measurement of the Yukawa coupling of the top quark using ttH events (ATLAS and CMS, all 3 channels high)
  9. Indirect measurement of the Yukawa coupling of the top quark from a global fit
  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 five new Omega_c states by LHCb
  15. Vub : Lambdab -> p mu nu
  16. CKM angle gamma: B± -> D0K±

Übungsgruppen

The seminar takes place on Tuedays 16:00 in Room 1.403. The talk dates will be posted here when finalised. 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:

  • 18 April 2017: 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
  • At the latest in week (n-1): dry run talk with the supervisor
  • After your talk: paper-like (with title, abstract, references etc) summary write-up of the topic, maximum 10 pages
