• More data• Google spreadsheet• Portuguese

CMS Masterclasses issues from 2014• Lack of 4-vector info:

• CMS Open Data.

• May become available in iSpy-online.

• Number of events per 2 students: still 100.

• Mentors can assign only 50, or

• Remember that doing all 100 is not the goal.

• Google spreadsheet issues:

• CIMA is under development and

• Will require a procedure rewrite.

CIMA:CMS Instrument for Masterclass Analysis

Created by Michael Soirin and Stefan Schoppman, Uni Aachen

Support from Tom McCauley and Dan Karmgard, Notre Dame

A little more like OPloT but students:

• Enter data into CIMA event-by-event.

• Build mass plot themselves.

Tested first time with students yesterday!

Clearly still in development but it works!

Like OPloT, CIMA has admin access to set up and edit data tables.

CMS Masterclass plans

Continue growth.

Mostly stable:

• Same measurement.

• Only minor changes to website.

New:

• CIMA.

• Possible improvements in iSpy-online and data organization.

IPPOG Masterclasses Meeting | CERN 6.11.2014 | Despina Hatzifotiadou

Looking for strange particles in ALICE

Topics

• Current status

• Results presentation

• Activities involving ALICE strangeness masterclasses

• Java version

• Opendata portal

IPPOG Masterclasses Meeting | CERN 6.11.2014 | Despina Hatzifotiadou

Current status : unchanged

First Part

•Students (each group): Visual analysis of 15 events / invariant mass histograms

•Institute (all groups): Add results / merge histograms / comments

Second Part

•Students (each group): Analyse events in a centrality bin - invariant mass histograms

•Students (each group): Fit curve/ subtract background-> find number of Λ, anti-Λ and K0s

•Institute (all groups): Calculate yields of each particle type

(give initial number of events from which each sample has been extracted;

give global efficiency)

•Calculate strangeness enhancement (ratio of yields normalised to Npart)

•Strangeness enhancement plots -> To be presented by Institutes for video-conference

ALICE strangeness masterclasses activities

• Masterclass as part of the Swedish Teachers programme at CERN

(31.10.2014 in 2 PC rooms at the CERN Training Centre)

28 persons (22 teachers and 6 High School students)

• Teachers’ Day in Thessaloniki (Greece) scheduled for 27 November 2014

Organised by EKFE (Centre for Laboratory Equipment for Natural Sciences) with

support from PLINET (Centre for Information Technology)

aim :Testbench for organizing local masterclasses in schools in the future

• Contacts with many Institutes outside Europe (expanding masterclasses WG)

Development of JAVA version

..a first version using JAVA developed by Patryk Marsinkowski (from Warsaw

University of Technology) with the help of Rafal Sarnecki

engineering thesis - February 2014

Basic tools are there ; needs to be completed

•Implement ALICE geometry

•Convert data sets (root files -> txt files)

•....

To be continued

IPPOG Masterclasses Meeting | CERN 6.11.2014 | Despina Hatzifotiadou

New opendata portal under construction

...for education and research : http://opendata.cern.ch/

Fully documented procedure, described athttp://opendata.cern.ch/VM/ALICE#configure

•install Virtual Box;•create a Virtual Machine•configure a Virtual Machine

Once this done, you are in an environment where you have •both ALICE masterclasses (strangeness and RAA) •a simple program producing PT distributions using released ALICE data

Alternative solution for running the masterclasses packagesindependent of operating system and installation of software tools (ROOT)

Large scale analysisROOT based analysis:

read data from a file, do calculations with these data, and fill histograms with the results

students “write code” (only “cut and paste”)challenging to complete the full measurement in time

share tasks among participating institutes

needs preparationdemonstrates the

value/power of collaborative work

International Masterclass 2014 one session April 1, 2014

~60 participants at 4 institutionsCairo, EgyptDarmstadt, GermanyFrankfurt, GermanyPrague, Czech Republic

same measurement as in previous years

no technical problems all groups ‘discovered’ the quark-gluon plasma positive feedback from all groups

R. Averbeck,216/11/2014

Plans for 2015 one session: March 13, 2015

up to now: 4 institutions (one more expected: Cairo, Egypt) new participant: Münster, Germany

no significant changes of the measurement software and instructions are available for

download in various formats, including a bootable DVD image: http://www-alice.gsi.de/masterclass/
