Light Z′ signatures at the LHC
(American Physical Society, 2023)In this work, we discuss a distinctive pp -> Higgs -> Z'Z' -> 4l (l = e, mu) signal at the LHC, where the "Higgs" label refers to the Standard Model-like Higgs state discovered in 2012 or a lighter one in the framework of ... -
The use of double-integral of experimental EPR spectra for tooth enamel EPR dosimetry
(Oxford University Press, 2023)The presence of background signal in tooth enamel EPR dosimetry is the most challenging situation to overcome. This becomes even more important because it obscures the radiation-induced signal, especially at radiation doses ... -
