Stable product
New:
• H
• 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

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/
