The strong CP problem is solved in Parity symmetric theories, with the electroweak gauge group containing SU(2)_{L}× SU(2)_{R}broken by the minimal set of Higgs fields. Neutrino masses may be explained by adding the same number of gauge singlet fermions as the number of generations. The neutrino masses vanish at treelevel and are only radiatively generated, leading to larger couplings of righthanded neutrinos to Standard Model particles than with the treelevel seesaw mechanism. We compute these radiative corrections and the mixing angles between left and righthanded neutrinos. We discuss sensitivities to these righthanded neutrinos from a variety of future experiments that search for heavy neutral leptons with masses from tens of MeV to the multiTeV scale.

A bstract We study a renormalizable model of Dirac fermion dark matter (DM) that communicates with the Standard Model (SM) through a pair of mediators — one scalar, one fermion — in the representation ( 6 , 1 , $$ \frac{4}{3} $$ 4 3 ) of the SM gauge group SU(3) c × SU(2) L × U(1) Y . While such assignments preclude direct coupling of the dark matter to the Standard Model at tree level, we examine the many effective operators generated at oneloop order when the mediators are heavy, and find that they are often phenomenologically relevant. We reinterpret dijet and pairproduced resonance and jets + $$ {E}_{\mathrm{T}}^{\mathrm{miss}} $$ E T miss searches at the Large Hadron Collider (LHC) in order to constrain the mediator sector, and we examine an array of DM constraints ranging from the observed relic density Ω χ $$ {h}_{\mathrm{Planck}}^2 $$ h Planck 2 to indirect and direct searches for dark matter. Treelevel annihilation, available for DM masses starting at the TeV scale, is required in order to produce Ω χ $$ {h}_{\mathrm{Planck}}^2 $$ h Planck 2 through freezeout, but loops — led by the dimensionfive DM magnetic dipole moment — are nonetheless able to produce signals large enough to be constrained, particularly by the XENON1T experiment. In some benchmarks, we find a fair amount of parameter space left open by experiment and compatible with freezeout. In other scenarios, however, the open space is quite small, suggesting a need for further modelbuilding and/or nonstandard cosmologies.more » « less

A bstract The standard model Higgs quartic coupling vanishes at (10 9 − 10 13 ) GeV. We study SU(2) L × SU(2) R × U(1) B−L theories that incorporate the Higgs Parity mechanism, where this becomes the scale of LeftRight symmetry breaking, v R . Furthermore, these theories solve the strong CP problem and predict three righthanded neutrinos. We introduce cosmologies where SU(2) R × U(1) B−L gauge interactions produce righthanded neutrinos via the freezeout or freezein mechanisms. In both cases, we find the parameter space where the lightest righthanded neutrino is dark matter and the decay of a heavier one creates the baryon asymmetry of the universe via leptogenesis. A theory of flavor is constructed that naturally accounts for the lightness and stability of the righthanded neutrino dark matter, while maintaining sufficient baryon asymmetry. The dark matter abundance and successful natural leptogenesis require v R to be in the range (10 10 − 10 13 ) GeV for freezeout, in remarkable agreement with the scale where the Higgs quartic coupling vanishes, whereas freezein requires v R ≳ 10 9 GeV. The allowed parameter space can be probed by the warmness of dark matter, precise determinations of the top quark mass and QCD coupling by future colliders and lattice computations, and measurement of the neutrino mass hierarchy.more » « less

We describe the confining instabilities of a proposed quantum spin liquid underlying the pseudogap metal state of the holedoped cuprates. The spin liquid can be described by a SU(2) gauge theory of
N _{f}= 2 massless Dirac fermions carrying fundamental gauge charges—this is the lowenergy theory of a meanfield state of fermionic spinons moving on the square lattice withπ flux per plaquette in the ℤ_{2}center of SU(2). This theory has an emergent SO(5)_{f}global symmetry and is presumed to confine at low energies to the Néel state. At nonzero doping (or smaller Hubbard repulsionU at halffilling), we argue that confinement occurs via the Higgs condensation of bosonic chargons carrying fundamental SU(2) gauge charges also moving inπ ℤ_{2}flux. At halffilling, the lowenergy theory of the Higgs sector hasN _{b}= 2 relativistic bosons with a possible emergent SO(5)_{b}global symmetry describing rotations between ad wave superconductor, period2 charge stripes, and the timereversal breaking “d density wave” state. We propose a conformal SU(2) gauge theory withN _{f}= 2 fundamental fermions,N _{b}= 2 fundamental bosons, and a SO(5)_{f}×SO(5)_{b}global symmetry, which describes a deconfined quantum critical point between a confining state which breaks SO(5)_{f}and a confining state which breaks SO(5)_{b}. The pattern of symmetry breaking within both SO(5)s is determined by terms likely irrelevant at the critical point, which can be chosen to obtain a transition between Néel order andd wave superconductivity. A similar theory applies at nonzero doping and largeU , with longerrange couplings of the chargons leading to charge order with longer periods. 
Abstract The coherent photoproduction of $$\mathrm{J}/\psi $$ J / ψ and $${\uppsi '}$$ ψ ′ mesons was measured in ultraperipheral Pb–Pb collisions at a centerofmass energy $$\sqrt{s_{\mathrm {NN}}}~=~5.02$$ s NN = 5.02 TeV with the ALICE detector. Charmonia are detected in the central rapidity region for events where the hadronic interactions are strongly suppressed. The $$\mathrm{J}/\psi $$ J / ψ is reconstructed using the dilepton ( $$l^{+} l^{}$$ l + l  ) and proton–antiproton decay channels, while for the $${\uppsi '}$$ ψ ′ the dilepton and the $$l^{+} l^{} \pi ^{+} \pi ^{}$$ l + l  π + π  decay channels are studied. The analysis is based on an event sample corresponding to an integrated luminosity of about 233 $$\mu {\mathrm{b}}^{1}$$ μ b  1 . The results are compared with theoretical models for coherent $$\mathrm{J}/\psi $$ J / ψ and $${\uppsi '}$$ ψ ′ photoproduction. The coherent cross section is found to be in a good agreement with models incorporating moderate nuclear gluon shadowing of about 0.64 at a Bjorken x of around $$6\times 10^{4}$$ 6 × 10  4 , such as the EPS09 parametrization, however none of the models is able to fully describe the rapidity dependence of the coherent $$\mathrm{J}/\psi $$ J / ψ cross section including ALICE measurements at forward rapidity. The ratio of $${\uppsi '}$$ ψ ′ to $$\mathrm{J}/\psi $$ J / ψ coherent photoproduction cross sections was also measured and found to be consistent with the one for photoproduction off protons.more » « less
