1
Beyond the standard model
wan ahmad tajuddin wan abdullah jabatan fizik universiti malaya
2
Current challenges in particle physics and cosmology
Phenomenology of the Standard Model - strong nuclear force - flavours - GUTs - Higgs sector Supersymmetry - does it exist? - role in unifying gravity with other forces TOE Dark matter and dark energy
3
Strong force – quantum chromodynamics
fragmentation exotic states
4
Flavours 3 generations? Leptonic sector – massive neutrinos
Weak eigenstates not energy eigenstates Leptonic sector – massive neutrinos - Majorana or Dirac? 3 generations?
5
CP (charge-parity) violation –
matter-antimatter asymmetry
6
Hierarchy problem supersymmetry? extra dimensions?
7
Grand Unification - how is QCD unified w electroweak?
gauge bosons, leptoquarks proton decay
8
Supersymmetry Supergravity – unification with gravity Superpartners?
GUT Gravity from fields
9
Theories of everything
Extra dimensions Superstrings Branes, M, etc QCD + EW from curvature
10
Dark matter – non-baryonic – stable neutrinos? – flavours
superparticles? from galaxy rotation; cosmology
11
Dark energy what?
12
Efforts in experimental particle physics by Malaysia
Energy frontier LHC Intensity frontier JPARC Belle SuperKEKB Cosmic frontier
13
ZEUS High energy electron on proton
- ended 2007, data analysis still ongoing electronics – read-out control hadron caloimetry fragmentation – baryons, strange correlations pentaquarks particle production – exlusive, diffractive
14
Data MC exclusive Y'
15
CMS TeV proton on proton - running electromagnetic calorimetry grid
jets SUSY
16
Belle II High intensity B factory - operating 2014 drift chamber
muon detector Monte Carlo cloud rare events - exclusive
17
COMET High intensity muon beam - initial stages Monte Carlo
flavour-changing muons
