nuclear matrix elements in the interacting boson model (IBM-2) with light and heavy neutrino
exchange are given for all nuclei of interest from 48Ca to 238U. The question of quenching of the
axial vector coupling constant gA in nuclei is discussed. Possible additional scenarios, such as
Majoron emission, and mechanisms, such as sterile neutrino exchanges, are also discussed.

Impact of the quenching of gA on the sensitivity of 0νββ experiments
Suhonen, Jouni (American Physical Society, 2017)Detection of the neutrinoless ββ (0νββ) decay is of high priority in the particle- and neutrino-physics communities. The detectability of this decay mode is strongly influenced by the value of the weak axial-vector coupling ... -
Jet quenching as a probe of the initial stages in heavy-ion collisions
Andres, Carlota; Armesto, Néstor; Niemi, Harri; Paatelainen, Risto; Salgado, Carlos A. (Elsevier, 2020)Jet quenching provides a very flexible variety of observables which are sensitive to different energy- and time-scales of the strongly interacting matter created in heavy-ion collisions. Exploiting this versatility would ... -
113Cdβ-decay spectrum and gA quenching using spectral moments
Kostensalo, Joel; Lisi, Eligio; Marrone, Antonio; Suhonen, Jouni (American Physical Society (APS), 2023)We present an alternative analysis of the 113Cdβ-decay electron energy spectrum in terms of spectral moments μn, corresponding to the averaged values of nth powers of the β particle energy. The zeroth moment μ0 is related ... -
