We are organizing a one-week school on MadGraph for LHC physics simulation at KIAS (Korea Institute for Advanced Studies) in Seoul, from Oct/24(Mon) to Oct/29(Sat).

The main lecturers/tutors of the school are as follows:

Johan Alwall (Fermilab)

MG5/ME overview, PS/MLM

Benjamin Fuks (Strasbourg)

FeynRules/UFO

Olivier Mattelaer (Louvain)

MG5/UFO/ALOHA

Rikkert Frederix (Zurich)

MadLoop/MadFKS/aMC@NLO

Grigory Kirilin (KEK)

PS/CKKW/Jets

Junichi Kanzaki (KEK)

MG/ME on GPU

MG5 is the latest version of MadGraph written in Python language, which allows us to generates codes for scattering matrix elements for any models described by a quantum field theory Lagrangian. ME stands for MadEvent which generates parton or hadronic events based on the matrix element. Matching of parton shower (PS) and matrix element is the key for realistic even simulations, and the MLM method with Pythia PS is adopted in ME. Johan and Olivier are the original authors of MG5 which solved many outstanding problem of the old MadGraph (Long-Stelzer, 1994) and is in the core of the following exciting developments.

FeynRules is a Mathematica package which produces Feynman Rules of an arbitrary Lagrangian model in the Universal FeynRules Output (UFO) format, which can then be made into Automatic Language-independent Output Helicity Amplitude (ALOHA) that is used to compute helicity amplitudes of any processes by MG5/ME. In short, you can now perform full LHC event simulation for any new physics models, as long as you can express them in the QFT language, once you master FeynRules and MG5/ME. Benjamin extended FeynRules to allow superfield formulation for MSSM and its extentions, and together with Olivier and others invented UFO. Up to this stage, both lectures and tutorials will be given in the school.

Another recent development is that MadGraph has been used to obtain loop corrections to tree-level amplitudes by using Cut-Tools (MadLoop), and by combining real emission with FKS counterterm events (MadFKS) automatic Monte Carlo parton shower event generation at NLO level of accuracy (aMC@NLO) has been achieved. Lectures by Rikkert will explain theoretical basis of these recent developments, and MC@NLO will be introduced in the tutorial session.

Interpretation of LHC physics results (well, also that of Tevatron results) requires deep understanding of QCD, especially that of parton shower which connects observable hadron jets and matrix elements of short distance physics which carry new physics information. Grigory's lectures will review theoretical basis of QCD parton shower and how jet observables should be analyzed.

Simulation of standard model background events often requires significant computation time. Fast parallel computation of matrix elements and event simulation on Graphic Processing Unit (GPU) have been developed at KEK, and Junichi will report on its latest status and give an on-line demonstration.

From Monday to Friday we will have three 1-hour lectures and one 3-hour tutorial session:

Details will yet to be discussed among lecturers/tutors, and will be given to all the participants. The participants will be requested to install tools (including MG5/Python and FeynRules/Mathematica) one week before the starting of the school. The list of, and links to, the required tools will be sent in a later bulletin. Linux or MAC operation system will be needed to run those tools.

The five 3-hours tutorial sessions are the core of the school, and we would like to restrict the number of students to be less than 30, in order to allow all the students to master the basic use of various tools.

Please fill in the following application form and send to

kaoru.hagiwara@kek.jp with cc to pko@kias.re.kr .

We accept all qualified students (those who have publication in collider physics or have good training in particle physics phenomenology), as well as post-doc's, staff's and seniors who have recent publication in collider phenomenology. Experimentalists working on new physics search are also encouraged to apply, and those who wishes to learn tools on this occasion may be considered if vacancy arises.

No deadline is set, since the school is only a month ahead of us. We make decision for each applicant, and inform of the acceptance/pending status immediately, until the number of accepted students reaches 30.

Registration fee of 50,000KW (or 4,000JPY, 40EUR, 50USD) will be collected upon registration, to cover coffee/tea/banquet.

Small amount of budget is available for those students who need local support.

We look forward to welcoming all of you who wish to contribute to new physics discovery at the LHC !
