Do we owe our existence to gravitational waves?
/ Ellis, John (King's Coll. London ; CERN) ; Fields, Brian D. (Illinois U., Urbana) ; Surman, Rebecca (Notre Dame U.)
Two heavy elements essential to human biology are thought to have been produced by the astrophysical $r$-process, which occurs in neutron-rich environments: iodine is a constituent of thyroid hormones that affect many physiological processes including growth and development, body temperature and heart rate, and bromine is essential for tissue development and architecture. Collisions of neutron stars (kilonovae) have been identified as sources of $r$-process elements including tellurium, which is adjacent to iodine in the periodic table, and lanthanides. [...]

UV Completion of Neutral Triple Gauge Couplings
/ Ellis, John (Shanghai Jiaotong U. ; King's Coll. London ; CERN) ; He, Hong-Jian (Shanghai Jiaotong U. ; Shanghai Jiao Tong U. ; Tsinghua U., Beijing ; Peking U., CHEP) ; Xiao, Rui-Qing (Shanghai Jiaotong U. ; King's Coll.

Neutral triple gauge couplings (nTGCs) are manifestation of new physics beyond the Standard Model (SM), as they are absent in the SM and are first generated by dimension-8 operators in the SM Effective Field Theory (SMEFT). [...]

Non-universal SUSY models, $g_\mu -2$, $m_H$ and dark matter
/ Ellis, John (King's Coll. London ; CERN) ; Olive, Keith A. (Minnesota U.) ; Spanos, Vassilis C. (Minnesota U. ; Athens U.)
We study the anomalous magnetic moment of the muon, $g_\mu - 2 \equiv 2 a_\mu$, in the context of supersymmetric models beyond the CMSSM, where the unification of either the gaugino masses $M_{1,2,3}$ or sfermion and Higgs masses is relaxed, taking into account the measured mass of the Higgs boson, $m_H$, the cosmological dark matter density and the direct detection rate. We find that the model with non-unified gaugino masses can make a contribution $\Delta a_\mu\sim 20 \times 10^{-10}$ to the anomalous magnetic moment of the muon, for example if $M_{1,2} \sim 600$ GeV and $M_3\sim 8$ TeV.

Neutral triple gauge couplings (nTGCs) are absent in the Standard Model (SM) and at the dimension-6 level in the Standard Model Effective Field Theory (SMEFT), arising first from dimension-8 operators. As such, they provide a unique window for probing new physics beyond the SM. [...]
