ATLAS双光子过剩的贝叶斯因子

Bayes-factor of the ATLAS diphoton excess

Andrew Fowlie

摘要:

根据ATLAS 8 TeV 20.3/fb、13 TeV 3.2/fb和13 TeV 15.4/fb的数据,我们提出了双伽马共振($\digamma$)与SM的贝叶斯因子的计算,避开了解释频率统计学意义的任何困难。我们尽可能匹配ATLAS分析中的参数化。根据8 TeV 20.3/fb和13 TeV 3.2/fb的ATLAS数据,我们计算出$\digamma$与标准模型相比的可解释性增加了大约8,这在一定程度上证明了对$\digamma$模型的兴趣。然而,根据15.4/fb的数据,总的来说,$\digamma$不利约0.7。

英文摘要:

We present a calculation of Bayes-factors for the digamma resonance ($\digamma$) versus the SM in light of ATLAS 8 TeV 20.3/fb, 13 TeV 3.2/fb and 13 TeV 15.4/fb data, sidestepping any difficulties in interpreting significances in frequentist statistics. We matched, wherever possible, parameterisations in the ATLAS analysis. We calculated that the plausibility of the $\digamma$ versus the Standard Model increased by about eight in light of the 8 TeV 20.3/fb and 13 TeV 3.2/fb ATLAS data, somewhat justifying interest in $\digamma$ models. All told, however, in light of 15.4/fb data, the $\digamma$ was disfavoured by about 0.7.
