BlackMax Update Meeting

Monday 16 Dec 2013, 11:00 → 13:00 Europe/Zurich

CERN

11:00 → 11:20 BlackMax3 Update

Speaker: Mr Warren Carlson (University of the Witwatersrand)

Slides BlackMax2Plots_Figures7_8_9.pdf BlackMax-Development-Meeting-2013-12-17(2).pdf

List of outstanding issues:

• Need to check that the units throughout the code are indeed in GeV
• Compare the different definitions of the extradimensional Gravitational Constant and Planck Scale used in the code with the ones in the literature (BlackMax Manual and published paper)
• Add units and legend to all plots
• In slide 9 of the talk, why is the range of the Hawking Temperature so little? Possible problem with units. The Schwarzschild radius units seem wrong too
• Also in slide 9, why is the range different for each value of n?
• To make direct comparisons with BlackMax, need to reproduce figures 1 and 2 of the BlackMax paper

11:20 → 11:40 BlacMax 3 Update 18th December

Speaker: Mr Warren Carlson

Slides BlackMax-Development-Meeting-2013-12-18.pdf

List of checks/outstanding issues:

• Check the gamma function against a standard one used in Mathematica/Maple (or against code found online)
• Dimensions of the M^* formula, at the moment that looks dimensionless
• Saw tooth behaviour in slide 3, plot each separate part of the function to understand where it comes from. Might be an issue with the gamma function
• Check formula in slide 5 against the literature
• Provide values for R_Sch and G_D from BlackMax2

11:40 → 12:00 BlackMax3 discussion 19th December

• Functions_NoCorrection.pdf

List of outstanding tasks:

• Remake the plots reproducing BlackMax2 results with the correct labels (done)
• BlackMax3: Validate all the Math libraries
• BlackMax3: Check throughout the code that the convention for the number of dimensions is consistent: can use "d" for total number of spacelike dimensions and "n" for the number of extra dimensions
• Need to reproduce figure 1 from the BlackMax PRD paper as a stepping stone towards reproducing figures 2-6
