ALFA Diffractive Analaysis Framework

Design

Data Format

The framework will use D3PD data that contain both ATLAS and ALFA information. It will operate only on ROOT files, so ATHENA support is not needed.

Technical Realisation

Shall it be ROOT standalone package or part of RootCore?

What Shall It Provide

1. A set of good tracks
2. Track matching between detectors
3. Number of reconstructed protons
4. Protons four-momenta

Implementation

Prerequisites

Data

1. The framework shall use TrackingData tree.

Suggestions and Comments

Please, insert here all your ideas concerning the framework

Rafal

• it would be good to have parts of common code for elastic and diffractive analyses
• parts of code that shall be common:
  • lumiblock selection
  • track selection based on quality
  • alignment
  • detector edge cuts
  • kinematic reconstruction
• it would be good to have user-friendly interface
• elastic analyses use ALFA ntuples while diffractive D3PDs, probably an interface class is needed in order to create common code
• elastic analysis use several trees at once, so the framework should be prepared for it

Currently Used Tools and Code

Please, insert here the description of the tools that are being used in the analyses and brief analysis code description or examples.
