energy spectra in KamLAND.
Main panel,
experimental points together with the total expectation (thin dotted black line).
Also shown are the total expected spectrum excluding the geoneutrino signal (thick solid black line),
the expected signals from
(dot-dashed red line) and
(dotted green line) geoneutrinos,
and the backgrounds due to reactor
(dashed light blue line),
reactions (dotted brown line),
and random coincidences (dashed purple line).
Inset,
expected spectra extended to higher energy.
The geoneutrino spectra are calculated from our reference model,
which assumes 16 TW radiogenic power from
and
 .
The error bars represent ±
1 standard deviation intervals.
