Standard model contribution to the electric dipole moment of the
  deuteron, $^3$H, and $^3$He nuclei

We calculate for the first time the electric dipole moment (EDM) of the
deuteron, $^3$H, and $^3$He nuclei generated by the one-meson exchange CP-odd
nuclear force in the standard model. The effective $|\Delta S| = 1$ four-quark
operators are matched to the $|\Delta S| = 1$ standard model processes
involving the CP phase of the Cabibbo-Kobayashi-Maskawa matrix at the
electroweak scale and run down to the hadronic scale $\mu = 1$ GeV according to
the renormalization group evolution in the next-to-leading logarithmic order.
At the hadronic scale, the hadron matrix elements are modeled in the
factorization approach. We then obtain the one-meson (pion, eta meson, and
kaon) exchange CP-odd nuclear force, which is the combination of the $|\Delta
S| = 1$ meson-baryon vertices which issue from the penguin operator and the
hyperon-nucleon transition. From this CP-odd nuclear force, the nuclear EDM is
calculated with the realistic Argonne $v18$ interaction and the CP-odd nuclear
force using the Gaussian expansion method. It is found that the EDMs of light
nuclear systems are of order $O(10^{-31}) e $ cm. We also estimate the standard
model contribution to other hadronic CP violating observables such as the EDMs
of $^6$Li, $^9$Be nuclei, and the atomic EDMs of $^{129}$Xe, $^{199}$Hg,
$^{211}$Rn, and $^{225}$Ra generated through the nuclear Schiff moment. We then
analyze the source of theoretical uncertainties and show some possible ways to
overcome them.Comment: 51 pages, 11 figures, published versio
Evaluation of conformal integrals

We present a comprehensive method for the evaluation of a vast class of
integrals representing 3-point functions of conformal field theories in
momentum space. The method leads to analytic, closed-form expressions for all
scalar and tensorial 3-point functions of operators with integer dimensions in
any spacetime dimension. In particular, this encompasses all 3-point functions
of the stress tensor, conserved currents and marginal scalar operators.Comment: 34 page, 1 figure; v3: several typos in formulae correcte
Consistent constraints on the Standard Model Effective Field Theory

We develop the global constraint picture in the (linear) effective field
theory generalisation of the Standard Model, incorporating data from detectors
that operated at PEP, PETRA, TRISTAN, SpS, Tevatron, SLAC, LEPI and LEP II, as
well as low energy precision data. We fit one hundred and three observables. We
develop a theory error metric for this effective field theory, which is
required when constraints on parameters at leading order in the power counting
are to be pushed to the percent level, or beyond, unless the cut off scale is
assumed to be large, $\Lambda \gtrsim \, 3 \, {\rm TeV}$. We more consistently
incorporate theoretical errors in this work, avoiding this assumption, and as a
direct consequence bounds on some leading parameters are relaxed. We show how
an $\rm S,T$ analysis is modified by the theory errors we include as an
illustrative example.Comment: 23 pages, + 19 page appendix, 9 figures, Acknowledgement updated with

Light-cone distribution amplitudes of the baryon octet

We present results of the first ab initio lattice QCD calculation of the
normalization constants and first moments of the leading twist distribution
amplitudes of the full baryon octet, corresponding to the small transverse
distance limit of the associated S-wave light-cone wave functions. The P-wave
(higher twist) normalization constants are evaluated as well. The calculation
is done using $N_f=2+1$ flavors of dynamical (clover) fermions on lattices of
different volumes and pion masses down to 222 MeV. Significant SU(3) flavor
symmetry violation effects in the shape of the distribution amplitudes are
observed.Comment: Update to the version published in JHE
Scenarios for Gluino Coannihilation

We study supersymmetric scenarios in which the gluino is the next-to-lightest
supersymmetric particle (NLSP), with a mass sufficiently close to that of the
lightest supersymmetric particle (LSP) that gluino coannihilation becomes
important. One of these scenarios is the MSSM with soft supersymmetry-breaking
squark and slepton masses that are universal at an input GUT renormalization
scale, but with non-universal gaugino masses. The other scenario is an
extension of the MSSM to include vector-like supermultiplets. In both
scenarios, we identify the regions of parameter space where gluino
coannihilation is important, and discuss their relations to other regions of
parameter space where other mechanisms bring the dark matter density into the
range allowed by cosmology. In the case of the non-universal MSSM scenario, we
find that the allowed range of parameter space is constrained by the
requirement of electroweak symmetry breaking, the avoidance of a charged LSP
and the measured mass of the Higgs boson, in particular, as well as the
appearance of other dark matter (co)annihilation processes. Nevertheless, LSP
masses $m_\chi \lesssim 8$~TeV with the correct dark matter density are quite
possible. In the case of pure gravity mediation with additional vector-like
supermultiplets, changes to the anomaly-mediated gluino mass and the threshold
effects associated with these states can make the gluino almost degenerate with
the LSP, and we find a similar upper bound.Comment: 25 pages, 22 figure
Virasoro vacuum block at next-to-leading order in the heavy-light limit

We consider the semiclassical limit of the vacuum Virasoro block describing
the diagonal 4-point correlation functions on the sphere. At large central
charge c, after exponentiation, it depends on two fixed ratios h_H/c and h_L/c,
where h_{H, L} are the conformal dimensions of the 4-point function operators.
The semiclassical block may be expanded in powers of the light ratio h_L/c and
the leading non-trivial (linear) order is known in closed form as a function of
h_H/c. Recently, this contribution has been matched against AdS_3 gravity
calculations where heavy operators build up a classical geometry corresponding
to a BTZ black hole, while the light operators are described by a geodesic in
this background. Here, we compute for the first time the next-to-leading
quadratic correction O((h_L/c)^{2}), again in closed form for generic heavy
operator ratio h_H/c. The result is a highly non-trivial extension of the
leading order and may be relevant for further refined AdS_{3}/CFT_{2} tests.
Applications to the two-interval R\'enyi entropy are also presented.Comment: 22 pages. v2 references adde
Non-BPS multi-bubble microstate geometries

We construct the first smooth horizonless supergravity solutions that have
two topologically-nontrivial three-cycles supported by flux, and that have the
same mass and charges as a non-extremal D1-D5-P black hole. Our configurations
are solutions to six-dimensional ungauged supergravity coupled to a tensor
multiplet, and uplift to solutions of Type IIB supergravity. The solutions
represent multi-center generalizations of the non-BPS solutions of Jejjala,
Madden, Ross, and Titchener, which have over-rotating angular momenta. By
adding an additional Gibbons-Hawking center, we succeed in lowering one of the
two angular momenta below the cosmic censorship bound, and bringing the other
very close to this bound. Our results demonstrate that it is possible to
construct multi-center horizonless solutions corresponding to non-extremal
black holes, and offer the prospect of ultimately establishing that
finite-temperature black holes have nontrivial structure at the horizon.Comment: 40 page
A supersymmetric Skyrme model

Construction of a supersymmetric extension of the Skyrme term was a
long-standing problem because of the auxiliary field problem; that is, the
auxiliary field may propagate and cannot be eliminated, and the problem of
having fourth-order time derivative terms. In this paper, we construct for the
first time a supersymmetric extension of the Skyrme term in four spacetime
dimensions, in the manifestly supersymmetric superfield formalism that does not
suffer from the auxiliary field problem. Chiral symmetry breaking in
supersymmetric theories results not only in Nambu-Goldstone (NG) bosons (pions)
but also in the same number of quasi-NG bosons so that the low-energy theory is
described by an SL(N,C)-valued matrix field instead of SU(N) for NG bosons. The
solution of auxiliary fields is trivial on the canonical branch of the
auxiliary field equation, in which case our model results in a fourth-order
derivative term that is not the Skyrme term. For the case of SL(2,C), we find
explicitly a nontrivial solution to the algebraic auxiliary field equations
that we call a non-canonical branch, which when substituted back into the
Lagrangian gives a Skyrme-like model. If we restrict to a submanifold, where
quasi-NG bosons are turned off, which is tantamount to restricting the Skyrme
field to SU(2), then the fourth-order derivative term reduces exactly to the
standard Skyrme term. Our model is the first example of a nontrivial auxiliary
field solution in a multi-component model.Comment: LaTeX: 21 pages, no figures; V2: published version (minor

A Novel Insulator by Holographic Q-lattices

We construct a bulk geometry with Q-lattice structure, which is implemented
by two gauge fields and a coupling between the lattice and the Maxwell field.
This gravity dual model can describe a novel insulator which exhibits some key
features analogous to Mott insulator. In particular, a hard gap in insulating
phase as well as vanishing DC conductivity can be simultaneously achieved. In
addition, we discuss the non-Drude behavior of the optical conductivity in low
frequency region in insulating phase, which exhibits some novel characteristics
different from ordinary Mott insulator.Comment: 14 pages, 6 figure
Charged hadrons in local finite-volume QED+QCD with C* boundary
  conditions

In order to calculate QED corrections to hadronic physical quantities by
means of lattice simulations, a coherent description of electrically-charged
states in finite volume is needed. In the usual periodic setup, Gauss's law and
large gauge transformations forbid the propagation of electrically-charged
states. A possible solution to this problem, which does not violate the axioms
of local quantum field theory, has been proposed by Wiese and Polley, and is
based on the use of C* boundary conditions. We present a thorough analysis of
the properties and symmetries of QED in isolation and QED coupled to QCD, with
C* boundary conditions. In particular we learn that a certain class of
electrically-charged states can be constructed in this setup in a fully
consistent fashion, without relying on gauge fixing. We argue that this class
of states covers most of the interesting phenomenological applications in the
framework of numerical simulations. We also calculate finite-volume corrections
to the mass of stable charged particles and show that these are much smaller
than in non-local formulations of QED.Comment: 63 pages. The main body spans 24 pages. The paper contains 4 extended

Relaxing the Electroweak Scale: the Role of Broken dS Symmetry

Recently, a novel mechanism to address the hierarchy problem has been
proposed \cite{Graham:2015cka}, where the hierarchy between weak scale physics
and any putative `cutoff' $M$ is translated into a parametrically large field
excursion for the so-called relaxion field, driving the Higgs mass to values
much less than $M$ through cosmological dynamics. In its simplest incarnation,
the relaxion mechanism requires nothing beyond the standard model other than an
axion (the relaxion field) and an inflaton. In this note, we critically
re-examine the requirements for successfully realizing the relaxion mechanism
and point out that parametrically larger field excursions can be obtained for a
given number of e-folds by simply requiring that the background break exact de
Sitter invariance. We discuss several corollaries of this observation,
including the interplay between the upper bound on the scale $M$ and the order
parameter $\epsilon$ associated with the breaking of dS symmetry, and entertain
the possibility that the relaxion could play the role of a curvaton. We find
that a successful realization of the mechanism is possible with as few as
$\mathcal O (10^3)$ e-foldings, albeit with a reduced cutoff $M \sim 10^6$ GeV
for a dark QCD axion and outline a minimal scenario that can be made consistent
with CMB observations.Comment: 16 pages, 3 figures. Version to appear in JHE
On universal knot polynomials

We present a universal knot polynomials for 2- and 3-strand torus knots in
adjoint representation, by universalization of appropriate Rosso-Jones formula.
According to universality, these polynomials coincide with adjoined colored
HOMFLY and Kauffman polynomials at SL and SO/Sp lines on Vogel's plane, and
give their exceptional group's counterparts on exceptional line. We demonstrate
that [m,n]=[n,m] topological invariance, when applicable, take place on the
entire Vogel's plane. We also suggest the universal form of invariant of figure
eight knot in adjoint representation, and suggest existence of such
universalization for any knot in adjoint and its descendant representation.
Properties of universal polynomials and applications of these results are
discussed.Comment: 26 pages, a number of misprints corrected, section 2.4 mainly sent to

Dyonic ISO(7) supergravity and the duality hierarchy

Motivated by its well defined higher dimensional origin, a detailed study of
$D=4$ $\mathcal{N}=8$ supergravity with a dyonically gauged $\textrm{ISO}(7) =
\textrm{SO}(7) \ltimes \mathbb{R}^7$ gauge group is performed. We write down
the Lagrangian and describe the tensor and duality hierarchies, focusing on an
interesting subsector with closed field equations and supersymmetry
transformations. We then truncate the $\mathcal{N}=8$ theory to some smaller
sectors with $\mathcal{N}=2$ and $\mathcal{N}=1$ supersymmetry and SU(3),
$\textrm{G}_2$ and SO(4) bosonic symmetry. Canonical and superpotential
formulations for these sectors are given, and their vacuum structure and
spectra is analysed. Unlike the purely electric ISO(7) gauging, the dyonic
gauging displays a rich structure of vacua, all of them AdS. We recover all
previously known ones and find a new $\mathcal{N}=1$ vacuum with SU(3) symmetry
and various non-supersymmetric vacua, all of them stable within the full
$\mathcal{N}=8$ theory.Comment: 52 pages, 4 tables. v2: Section 2.4 on critical points added. v3:

Brane induced supersymmetry breaking and de Sitter supergravity

We obtain a four-dimensional supergravity with spontaneously broken
supersymmetry allowing for de Sitter vacua by coupling a superspace action of
minimal N=1, D=4 supergravity to a locally supersymmetric generalization of the
Volkov-Akulov goldstino action describing the dynamics of a space-filling
non-BPS 3-brane in N=1, D=4 superspace. To the quadratic order in the goldstino
field the obtained action coincides with earlier constructions of
supergravities with nilpotent superfields, while matching the higher-order
contributions will require a non-linear redefinition of fields. In the unitary
gauge, in which the goldstino field is set to zero, the action coincides with
that of Volkov and Soroka. We also show how a nilpotency constraint on a chiral
curvature superfield emerges in this formulation.Comment: 29 pages, v2: typos corrected, references adde
Low-derivative operators of the Standard Model effective field theory
  via Hilbert series methods

In this work, we explore an extension of Hilbert series techniques to count
operators that include derivatives. For sufficiently low-derivative operators,
we find an algorithm that gives the number of invariant operators, properly
accounting for redundancies due to the equations of motion and integration by
parts. Specifically, the technique can be applied whenever there is only one
Lorentz invariant for a given partitioning of derivatives among the fields. At
higher numbers of derivatives, equation of motion redundancies can be removed,
but the increased number of Lorentz contractions spoils the subtraction of
integration by parts redundancies. While restricted, this technique is
sufficient to automatically generate the complete set of invariant operators of
the Standard Model effective field theory for dimensions 6 and 7 (for arbitrary
numbers of flavors). At dimension 8, the algorithm does not automatically
generate the complete operator set; however, it suffices for all but five
classes of operators. For these remaining classes, there is a well defined
procedure to manually determine the number of invariants. Using these methods,
we thereby derive the set of 535 dimension-8 $N_f = 1$ operators.Comment: 32 pages, corrected small mistakes, added reference
Higher-Order QCD Predictions for Dark Matter Production in Mono-$Z$
  Searches at the LHC

We present theoretical predictions for mono-$Z$ production in the search for
dark matter in Run-II at the LHC, including next-to-leading order QCD
corrections and parton-shower effects. We consider generic simplified models
with vector and scalar $s$-channel mediators. The calculation is performed by
implementing the simplified models in the FeynRules/MadGraph5_aMC@NLO
framework, which allows us to include higher-order QCD corrections and
parton-shower effects in an automated way. We find that these corrections are
sizeable and help to reduce the theoretical uncertainties. We also investigate
the discovery potential in several benchmark scenarios in the 13 TeV run at the
LHC.Comment: 29 pages, 12 figures; v2: references adde
Impact of sterile neutrinos on nuclear-assisted cLFV processes

We discuss charged lepton flavour violating processes occurring in the
presence of muonic atoms, such as muon-electron conversion in nuclei
$\text{CR}(\mu -e, \text{ N})$, the (Coulomb enhanced) decay of muonic atoms
into a pair of electrons BR($\mu^- e^- \to e^- e^-$, N), as well as Muonium
conversion and decay, $\text{Mu}-\bar{\text{Mu}}$ and $\text{Mu}\to e^+ e^-$.
Any experimental signal of these observables calls for scenarios of physics
beyond the Standard Model. In this work, we consider minimal extensions of the
Standard Model via the addition of sterile fermions, providing the
corresponding complete analytical expressions for all the considered
observables. We first consider an "ad hoc" extension with a single sterile
fermion state, and investigate its impact on the above observables. Two well
motivated mechanisms of neutrino mass generation are then considered: the
Inverse Seesaw embedded into the Standard Model, and the $\nu$MSM. Our study
reveals that, depending on their mass range and on the active-sterile mixing
angles, sterile neutrinos can give significant contributions to the above
mentioned observables, some of them even lying within present and future
sensitivity of dedicated cLFV experiments. We complete the analysis by
confronting our results to other (direct and indirect) searches for sterile
fermions.Comment: 32 pages, 11 figures. v2: minor revision, matches published version

Prospects for Spin-1 Resonance Search at 13 TeV LHC and the ATLAS
  Diboson Excess

Motivated by ATLAS diboson excess around 2 TeV, we investigate a
phenomenology of spin-1 resonances in a model where electroweak sector in the
SM is weakly coupled to strong dynamics. The spin-1 resonances, W' and Z', are
introduced as effective degrees of freedom of the dynamical sector. We explore
several theoretical constraints by investigating the scalar potential of the
model as well as the current bounds from the LHC and precision measurements. It
is found that the main decay modes are V' -> VV and V' -> Vh, and the V' width
is narrow enough so that the ATLAS diboson excess can be explained. In order to
investigate future prospects, we also perform collider simulations at the 13
TeV LHC, and obtain a model independent expected exclusion limit for the
process pp -> W' -> WZ -> JJ. We find a parameter space where the diboson
excess can be explained, and are within a reach of the LHC at the integrated
luminosity of 10 fb-1 and 13 TeV.Comment: 38 pages, 19 figures, 1 table; minor changes, references added,

Model independent constraints on four-lepton operators

We obtain constraints on four-lepton interactions in the effective field
theory with dimension-6 operators. To this end, we combine the experimental
input from Z boson measurements in LEP-1, W boson mass and decays, muon and tau
decays, lepton pair production in LEP-2, neutrino scattering on electrons, and
parity violating electron scattering. The analysis does not rely on any
assumptions about the flavor structure of the dimension-6 operators. Our main
results are the confidence intervals for Wilson coefficients of 16
lepton-flavor conserving four-lepton operators, together with the full
correlation matrix. Consequences for leptophilic models beyond the Standard
Model are discussed.Comment: 26 pages; v2: refs added, discussion of Michel parameters extende
Varieties of Abelian mirror symmetry on $\mathbb{RP}^2 \times
  \mathbb{S}^1$

We study 3d mirror symmetry with loop operators, Wilson loop and Vortex loop,
and multi-flavor mirror symmetry through utilizing the $\mathbb{RP}^2 \times
\mathbb{S}^1$ index formula. The key identity which makes the above description
work well is the mod 2 version of the Fourier analysis, and we study such
structure, the S-operation in the context of a SL$(2,\mathbb{Z})$ action on 3d
SCFTs. We observed that two types of the parity conditions basically associated
with gauge symmetries which we call $\mathcal{P}$-type and $\mathcal{CP}$-type
are interchanged under mirror symmetry. We will also comment on the
T-operation.Comment: 24 pages; v2: reference added; v3: formulas modified, comments added,

Phenomenology of NMSSM in TeV scale mirage mediation

We study the next-to-minimal supersymmetric standard model (NMSSM) with the
TeV scale mirage mediation, which is known as a solution for the little
hierarchy problem in supersymmetry. Our previous study showed that 125 GeV
Higgs boson is realized with O(10) % fine-tuning for 1.5 TeV gluino (1 TeV
stop) mass. The $\mu$ term could be as large as 500 GeV without sacrificing the
fine-tuning thanks to a cancellation mechanism. The singlet-doublet mixing is
suppressed by $\tan\beta$. In this paper, we further extend this analysis. We
argue that approximate scale symmetries play a role behind the suppression of
the singlet-doublet mixing. They reduce the mixing matrix to a simple form that
is useful to understand the results of the numerical analysis. We perform a
comprehensive analysis of the fine-tuning including the singlet sector by
introducing a simple formula for the fine-tuning measure. This shows that the
singlet mass of the least fine-tuning is favored by the LEP anomaly for
moderate $\tan\beta$. We also discuss prospects for the precision measurements
of the Higgs couplings at LHC and ILC and direct/indirect dark matter searches
in the model.Comment: 47 pages, 46 figures, version accepted by JHE

bi-local representation we discuss the emergent bulk space-time and
construction of (Higher spin) fields. We note the presence of `evanescent'
