    “…Here, we outline the steps required to express the $0\nu\beta\beta$ half-life in terms of the effective interactions, focusing on the dimension-five operator that induces a Majorana mass for the neutrinos. This process involves the evolution of the operators down to scales of a few GeV where they can be matched onto Chiral Perturbation Theory. …”

    “…In this work, we summarize the current status of plans for the FPF, including recent progress in civil engineering in identifying promising sites for the FPF; the FPF experiments currently envisioned to realize the FPF’s physics potential; and the many Standard Model and new physics topics that will be advanced by the FPF, including searches for long-lived particles, probes of dark matter and dark sectors, high-statistics studies of TeV neutrinos of all three flavors, aspects of perturbative and non-perturbative QCD, and high-energy astroparticle physics.…”

    “…Fully leptonic final states have been considered, selecting events with exactly two opposite-sign leptons (either electrons or muons) and missing transverse energy due to the escaping neutrinos. Additionally, at least two jets with large pseudorapidity gap (\ensuremath{\Delta\eta_{\mathrm{jj}}}) and high invariant mass (\ensuremath{m_{\mathrm{jj}}}) are required, which are produced in association with the two W bosons. …”

    “…We present the argument that the geometrical beauty of the ADDK Manyfold Universe is enough to exclude the "exotic" forms of "Dark Matter" predicted by some physical theories but never observed experimentally.We argue that if "Dark Matter" can raise by 7 times the spinning rotation of spiral arms of Galaxies around their Nuclei then "Dark Matter" should have been detected at least in our Galaxy by a very precise instrument as the NASA Chandra Satellite.Since nothing has been found and something so massive to raise 7 times the spinning speed of spiral arms cannot evade detection by highly accurate instruments we conclude that the "exotic forms of Dark Matter" which means to say WIMPS,Axions,Neutralinos,Heavy or Strange Neutrinos or other exotic forms of "Baryonic Dark Matter" dont have physical existance and we propose the natural and geometrical beauty of the Manyfold Universe provides the physical and correct explanation for "Dark Matter". …”

    “…In addition to detecting mu /sup +/ mu /sup -/ events arising from electromagnetic sources (e.g. rho to mu /sup +/ mu /sup -/, psi to mu /sup +/ mu /sup -/ etc.) they have observed mu /sup +/ mu /sup -/ pairs associated with a significant amount of missing energy indicative of final state neutrinos. Interpreting these data as production of DD pairs followed by single or double muonic decays leads to a model dependent estimate of total production cross-section of order 15 mu b. (14 refs).…”

Although never observed as elementary particles, quasiparticles with Weyl dispersion have recently been experimentally discovered in solid-state systems causing a furore in the research community. …”

    “…Following a CMS study, we investigate theoretical issues in using measurements of gamma + 2-jet production to predict the irreducible background to searches for missing energy plus two jets that originates from Z + 2-jet production where the Z boson decays to neutrinos. We compute ratios of gamma + 2-jet to Z + 2-jet production cross sections and kinematic distributions at next-to-leading order in alpha_s, as well as using a parton shower matched to leading-order matrix elements. …”

    “…Instead, it suffices if new CP-violating interactions at high energies result in primordial charge asymmetries, which are then reprocessed into a nonvanishing B−L asymmetry by right-handed neutrinos (RHNs) at lower energies. In this paper, we study this novel mechanism known as wash-in leptogenesis, utilizing axion inflation as the source of high-scale CP violation. …”
