Resummed photon spectrum from dark matter annihilation for intermediate and narrow energy resolution

Abstract

The annihilation cross section of weakly interacting TeV scale dark matter particles ${\chi }^0$ into photons is affected by large quantum corrections due to electroweak Sudakov logarithms and the Sommerfeld effect. We extend our previous work on the resummation of the semi-inclusive photon energy spectrum in ${\chi }^0{\chi }^0\to \gamma +X$ in the vicinity of the maximal photon energy $E_{\gamma }=m_{\chi }$ with NLL' accuracy from the case of narrow photon energy resolution $E_{\mathrm{res}}^{\gamma }$ of order $m_W^2/m_{\chi }$ to intermediate resolution of order $E_{\mathrm{res}}^{\gamma }\sim m_W$. We also provide details on the previous narrow resolution calculation. The two calculations, performed in different effective field theory set-ups for the wino dark matter model, are then shown to match well, providing an accurate representation up to energy resolutions of about 300 GeV.
