[BDXlist] [EXTERNAL] BDX in JLab at 24 GeV white paper

Tue May 30 07:40:48 EDT 2023

Dear Colleagues

Attached you can find the new plot. 

About the text, I propose to add the following sentence to the caption of the figure :

“The 90% CL  BDX sensitivity by using a 22 GeV (green line) electron beam. Limits are given for the scaling parameter y, proportional to the LDM-SM interaction cross section, as a function
of the LDM mass mχ. The curve refers to the ideal case of a zero-background measurement, considering a 300 MeV energy threshold and assuming an overall 20% signal efficiency”

Let me know if this you agree with this modification and you have any comments/suggestions within today. After that I will ask to Patrizia the possibility of text changing. 

Best regards
Mariangela
