About
Data focuses on high-energy physics events involving the Z boson, a neutral elementary particle that mediates the weak force. The primary purpose of this resource is to facilitate the development of machine learning models capable of distinguishing between two key decay modes of the Z boson. These modes are Zee (decay into two electrons) and Zmumu (decay into two muons), both of which produce lepton pairs with an invariant mass close to that of the Z boson. This resource is essential for binary classification tasks in particle physics research.
Columns
The dataset includes several features describing the event and the resulting leptons:
- Run: The unique run number identifying the data collection period for the event.
- Event: The specific event number recorded.
- pt (pt1, pt2): The transverse momentum of the observed lepton (either muon or electron), measured in units of GeV. The mean transverse momentum for the first lepton is 39.1, with a maximum recorded value of 269.
- eta (eta1, eta2): The pseudorapidity of the lepton. The mean pseudorapidity for the first lepton is -0.14.
- phi (phi1, phi2): The phi angle of the lepton, measured in radians.
- Q (Q1, Q2): The charge of the observed lepton (either -1 or 1).
- class: The target variable, distinguishing between Zee and Zmumu decay events.
Distribution
The information is available in a single CSV file, named
Z_boson.csv, which is 1.55 MB in size. The dataset contains 20,000 valid records. All primary feature columns, such as those detailing momentum, angle, and charge, maintain perfect data quality with 100% validity and no missing or mismatched entries.Usage
This resource is perfectly suited for analysts and physicists looking to apply binary classification techniques to experimental data. It enables the building of predictive models to identify and classify particle decay modes. Users can employ the data for detailed data analytics and exploratory studies to understand the kinematic properties of leptons resulting from Z boson decay.
Coverage
The material exclusively covers physics events related to Z boson decay, specifically Zee and Zmumu events. The scope is defined by 20,000 recorded observations detailing the kinematic properties of the resulting lepton pairs. The data is static and no future updates are anticipated.
