String tensions in deformed Yang-Mills theory

We study k-strings in deformed Yang-Mills (dYM) with SU(N) gauge group in the
semiclassically calculable regime on ${\rm I\!R}^3 \times S^1$. Their tensions
T$_{\text{k}}$ are computed in two ways: numerically, for $2$ $\le$ N $\le$
$10$, and via an analytic approach using a re-summed perturbative expansion.
The latter serves both as a consistency check on the numerical results and as a
tool to analytically study the large-N limit. We find that dYM k-string ratios
T$_{\text{k}}$/T$_{\text{1}}$ do not obey the well-known sine- or
Casimir-scaling laws. Instead, we show that the ratios
T$_{\text{k}}$/T$_{\text{1}}$ are bound above by a square root of Casimir
scaling, previously found to hold for stringlike solutions of the MIT Bag
Model. The reason behind this similarity is that dYM dynamically realizes, in a
theoretically controlled setting, the main model assumptions of the Bag Model.
We also compare confining strings in dYM and in other four-dimensional theories
with abelian confinement, notably Seiberg-Witten theory, and show that the
unbroken $Z_N$ center symmetry in dYM leads to different properties of
k-strings in the two theories; for example, a "baryon vertex" exists in dYM but
not in softly-broken Seiberg-Witten theory. Our results also indicate that, at
large values of N, k-strings in dYM do not become free.Comment: v3: To be published version, 78 pages, 7 figures, Added extended

Upper bound on the Abelian gauge coupling from asymptotic safety

We explore the impact of asymptotically safe quantum gravity on the Abelian
gauge coupling in a model including a charged scalar, confirming indications
that asymptotically safe quantum fluctuations of gravity could trigger a
power-law running towards a free fixed point for the gauge coupling above the
Planck scale. Simultaneously, quantum gravity fluctuations balance against
matter fluctuations to generate an interacting fixed point, which acts as a
boundary of the basin of attraction of the free fixed point. This enforces an
upper bound on the infrared value of the Abelian gauge coupling. In the regime
of gravity couplings which in our approximation also allows for a prediction of
the top quark and Higgs mass close to the experimental value [1], we obtain an
upper bound approximately 35% above the infrared value of the hypercharge
coupling in the Standard Model.Comment: 14 pages + appendix, 13 figure
Supersymmetric vortex defects in two dimensions

We study codimension-two BPS defects in 2d N=(2,2) supersymmetric gauge
theories, focusing especially on those characterized by vortex-like
singularities in the dynamical or non-dynamical gauge field. We classify
possible SUSY-preserving boundary conditions on charged matter fields around
the vortex defects, and derive a formula for defect correlators on the squashed
sphere. We also prove an equivalence relation between vortex defects and 0d-2d
coupled systems. Our defect correlators are shown to be consistent with the
mirror symmetry duality between Abelian gauged linear sigma models and
Landau-Ginzburg models, as well as that between the minimal model and its
orbifold. We also study the vortex defects inserted at conical singularities.Comment: 67 pages; v2: typos corrected, references added, v3: typos corrected,

Defect multiplets of N=1 supersymmetry in 4d

Any 4d theory possessing $\mathcal{N}=1$ supersymmetry admits a so called
$\mathcal{S}$-multiplet, containing the conserved energy-momentum tensor and
supercurrent. When a defect is introduced into such a theory, the
$\mathcal{S}$-multiplet receives contributions localised on the defect, which
indicate the breaking of some translation symmetry and consequently also some
supersymmetries. We call this the defect multiplet. We classify such terms
corresponding to half-BPS defects which can be either three-dimensional,
preserving 3d $\mathcal{N}=1$, or two-dimensional, preserving
$\mathcal{N}=(0,2)$. The new terms localised on the defect furnish multiplets
of the reduced symmetry and give rise to the displacement operator
Bootstrapping 3D Fermions with Global Symmetries

We study the conformal bootstrap for 4-point functions of fermions $\langle
\psi_i \psi_j \psi_k \psi_{\ell} \rangle$ in parity-preserving 3d CFTs, where
$\psi_i$ transforms as a vector under an $O(N)$ global symmetry. We compute
bounds on scaling dimensions and central charges, finding features in our
bounds that appear to coincide with the $O(N)$ symmetric Gross-Neveu-Yukawa
fixed points. Our computations are in perfect agreement with the $1/N$
expansion at large $N$ and allow us to make nontrivial predictions at small
$N$. For values of $N$ for which the Gross-Neveu-Yukawa universality classes
are relevant to condensed-matter systems, we compare our results to previous
analytic and numerical results.Comment: 29 pages, 7 figure
LHC Search for Right-handed Neutrinos in $Z^\prime$ Models

We consider right-handed neutrino pair production in generic $Z^\prime$
models. We propose a new, model-independent analysis using final states
containing a pair of same-sign muons. A key aspect of this analysis is the
reconstruction of the RH neutrino mass, which leads to a significantly improved
sensitivity. Within the $U(1)_{(B-L)_{3}}$ model, we find that at the HL-LHC it
will be possible to probe RH neutrino masses in the range $0.2\lesssim M_{N_R}
\lesssim 1.1\,$TeV.Comment: 6 pages, 5 figure
6d surface defects from massive type IIA

We present a new BPS flow within minimal $\mathcal{N}=1$ supergravity in
seven dimensions describing a warped $\textrm{AdS}_{3}$ background supported by
a "dyonic" profile of the three-form. Furthermore, we discuss the holographic
interpretation of the above solution in terms of a defect $\textrm{SCFT}_{2}$
inside the 6d $(1,0)$ theory dual to the AdS in the asymptotic region. Finally
we provide the brane picture of the aforementioned defect CFT as D2- and
wrapped D4-branes ending on a D6 - NS5 - D8 funnel in massive type IIA string
theory.Comment: 16 pages, 2 figures; v2: minor corrections, published version; v3:

One Thousand and One Bubbles

We propose a novel strategy that permits the construction of completely
general five-dimensional microstate geometries on a Gibbons-Hawking space. Our
scheme is based on two steps. First, we rewrite the bubble equations as a
system of linear equations that can be easily solved. Second, we conjecture
that the presence or absence of closed timelike curves in the solution can be
detected through the evaluation of an algebraic relation. The construction we
propose is systematic and covers the whole space of parameters, so it can be
applied to find all five-dimensional BPS microstate geometries on a
Gibbons-Hawking base. As a first result of this approach, we find that the
spectrum of scaling solutions becomes much larger when non-Abelian fields are
present. We use our method to describe several smooth horizonless multicenter
solutions with the asymptotic charges of three-charge (Abelian and non-Abelian)
black holes. In particular, we describe solutions with the centers lying on
lines and circles that can be specified with exact precision. We show the power
of our method by explicitly constructing a 50-center solution. Moreover, we use
it to find the first smooth five-dimensional microstate geometries with
arbitrarily small angular momentum.Comment: 33 pages. v2: typos correcte
Extremal Vanishing Horizon Kerr-AdS Black Holes at Ultraspinning Limit

By utilizing the ultraspinning limit we generate a new class of extremal
vanishing horizon (EVH) black holes in odd dimensions ($d\geq5$). Starting from
the general multi-spinning Kerr-AdS metrics, we show the EVH limit commutes
with the ultraspinning limit, in which the resulting solutions possess a
non-compact but finite area manifold for all $(t,r\neq r_+)=const.$ slices. We
also demonstrate the near horizon geometries of obtained ultraspinning EVH
solutions contain an AdS$_3$ throats, where it would be a BTZ black hole in the
near EVH cases. The commutativity of the ultraspinning and near horizon limits
for EVH solutions is confirmed as well. Furthermore, we discuss only
five-dimensional case near the EVH point can be viewed as a super-entropic
black hole. We also show that the thermodynamics of the obtained solutions
agree with the BTZ black hole. Moreover we investigate the EVH/CFT proposal,
demonstrating the entropy of $2$d dual CFT and Bekenstein-Hawking entropy are
equivalent.Comment: 29 pages, 3 figure
ADE String Chains and Mirror Symmetry

6d superconformal field theories (SCFTs) are the SCFTs in the highest
possible dimension. They can be geometrically engineered in F-theory by
compactifying on non-compact elliptic Calabi-Yau manifolds. In this paper we
focus on the class of SCFTs whose base geometry is determined by $-2$ curves
intersecting according to ADE Dynkin diagrams and derive the corresponding
mirror Calabi-Yau manifold. The mirror geometry is uniquely determined in terms
of the mirror curve which has also an interpretation in terms of the
Seiberg-Witten curve of the four-dimensional theory arising from torus
compactification. Adding the affine node of the ADE quiver to the base
geometry, we connect to recent results on SYZ mirror symmetry for the $A$ case
and provide a physical interpretation in terms of little string theory. Our
results, however, go beyond this case as our construction naturally covers the
$D$ and $E$ cases as well.Comment: version 2: typos corrected, 30 pages, 8 figure
Transverse momentum in double parton scattering: factorisation,
  evolution and matching

We give a description of double parton scattering with measured transverse
momenta in the final state, extending the formalism for factorisation and
resummation developed by Collins, Soper and Sterman for the production of
colourless particles. After a detailed analysis of their colour structure, we
derive and solve evolution equations in rapidity and renormalisation scale for
the relevant soft factors and double parton distributions. We show how in the
perturbative regime, transverse momentum dependent double parton distributions
can be expressed in terms of simpler nonperturbative quantities and compute
several of the corresponding perturbative kernels at one-loop accuracy. We then
show how the coherent sum of single and double parton scattering can be
simplified for perturbatively large transverse momenta, and we discuss to which
order resummation can be performed with presently available results. As an
auxiliary result, we derive a simple form for the square root factor in the
Collins construction of transverse momentum dependent parton distributions.Comment: 113 pages, 14 figures. v2: additional discussion, especially in

Wrapping rules (in) string theory

In this paper we show that the number of all 1/2-BPS branes in string theory
compactified on a torus can be derived by universal wrapping rules whose
formulation we present. These rules even apply to branes in less than ten
dimensions whose ten-dimensional origin is an exotic brane. In that case the
wrapping rules contain an additional combinatorial factor that is related to
the highest dimension in which the ten-dimensional exotic brane, after
compactification, can be realized as a standard brane. We show that the
wrapping rules also apply to cases with less supersymmetry. As a specific
example, we discuss the compactification of IIA/IIB string theory on
$(T^4/{\mathbb{Z}_2}) \times T^n$.Comment: 21 page
Comments on Higher Rank Wilson Loops in ${\cal N}=2^*$

For ${\cal N}=2^*$ theory with $U(N)$ gauge group we evaluate expectation
values of Wilson loops in representations described by a rectangular Young
tableau with $n$ rows and $k$ columns. The evaluation reduces to a two-matrix
model and we explain, using a combination of numerical and analytical
techniques, the general properties of the eigenvalue distributions in various
regimes of parameters $(N,\lambda,n,k)$ where $\lambda$ is the 't Hooft
coupling. In the large $N$ limit we present analytic results for the leading
and sub-leading contributions. In the particular cases of only one row or one
column we reproduce previously known results for the totally symmetry and
totally antisymmetric representations. We also extensively discusss the ${\cal
N}=4$ limit of the ${\cal N}=2^*$ theory. While establishing these connections
we clarify aspects of various orders of limits and how to relax them; we also
find it useful to explicitly address details of the genus expansion. As a
result, for the totally symmetric Wilson loop we find new contributions that
improve the comparison with the dual holographic computation at one loop order
in the appropriate regime.Comment: 28 pages, 4 figures. v2: References added. v3: More references, JHEP

Black hole holography and mean field evolution

Holographic theories representing black holes are expected to exhibit quantum
chaos. We argue if the laws of quantum mechanics are expected to hold for
observers inside such black holes, then such holographic theories must have a
mean field approximation valid for typical black hole states, and for
timescales approaching the scrambling time. Using simple spin models as
examples, we examine the predictions of such an approach for observers inside
black holes, and more speculatively inside cosmological horizons.Comment: 11 pages, 5 figure
Locally non-geometric fluxes and missing momenta in M-theory

We use exceptional field theory to describe locally non-geometric spaces of
M-theory of more than three dimensions. For these spaces, we find a new set of
locally non-geometric fluxes which lie in the R-R sector in the weak-coupling
limit and can typically be characterised by mixed symmetry tensors. These
spaces thus provide new examples of non-geometric backgrounds which go beyond
the NS-NS sector of string theory. Starting from twisted tori we construct
duality chains that lead to these new non-geometric backgrounds and we show
that, just as in the four-dimensional case, there are missing momenta
associated to the mixed symmetry tensors.Comment: 49 pages; v2: Published version, minor changes mad
Partially composite Higgs models: Phenomenology and RG analysis

We study the phenomenology of partially composite-Higgs models where
electroweak symmetry breaking is dynamically induced, and the Higgs is a
mixture of a composite and an elementary state. The models considered have
explicit realizations in terms of gauge-Yukawa theories with new strongly
interacting fermions coupled to elementary scalars and allow for a very SM-like
Higgs state. We study constraints on their parameter spaces from vacuum
stability and perturbativity as well as from LHC results and find that
requiring vacuum stability up to the compositeness scale already imposes
relevant constraints. A small part of parameter space around the classically
conformal limit is stable up to the Planck scale. This is however already
strongly disfavored by LHC results. In different limits, the models realize
both (partially) composite-Higgs and (bosonic) technicolor models and a
dynamical extension of the fundamental Goldstone-Higgs model. Therefore, they
provide a general framework for exploring the phenomenology of composite
dynamics.Comment: 24 pages, 11 figures. v2 matches the published versio
Entanglement of heavy quark impurities and generalized gravitational
  entropy

We calculate the contribution from non-conformal heavy quark sources to the
entanglement entropy (EE) of a spherical region in N=4 SUSY Yang-Mills theory.
We apply the generalized gravitational entropy method to non-conformal probe
D-brane embeddings in AdS_5 x S^5, dual to pointlike impurities exhibiting
flows between quarks in large-rank tensor representations and the fundamental
representation. For the D5-brane embedding which describes the screening of
fundamental quarks in the UV to the antisymmetric tensor representation in the
IR, the EE excess decreases non-monotonically towards its IR asymptotic value,
tracking the qualitative behaviour of the one-point function of static fields
sourced by the impurity. We also examine two classes of D3-brane embeddings,
one which connects a symmetric representation source in the UV to fundamental
quarks in the IR, and a second category which yields the symmetric
representation source on the Coulomb branch. The EE excess for the former
increases from the UV to the IR, whilst decreasing and becoming negative for
the latter. In all cases, the probe free energy on hyperbolic space with
\beta=2\pi, increases monotonically towards the IR, supporting its
interpretation as a relative entropy. We identify universal corrections,
depending logarithmically on the VEV, for the symmetric representation on the
Coulomb branch.Comment: 40 pages, 10 figure
Adiabatic suppression of the axion abundance and isocurvature due to
  coupling to hidden monopoles

The string theory predicts many light fields called moduli and axions, which
cause a cosmological problem due to the overproduction of their coherent
oscillation after inflation. One of the prominent solutions is an adiabatic
suppression mechanism, which, however, is non-trivial to achieve in the case of
axions because it necessitates a large effective mass term which decreases as a
function of time. The purpose of this paper is twofold. First, we provide an
analytic method to calculate the cosmological abundance of coherent oscillation
in a general situation under the adiabatic suppression mechanism. Secondly, we
apply our method to some concrete examples, including the one where a string
axion acquires a large effective mass due to the Witten effect in the presence
of hidden monopoles.Comment: 30 pages, 3 figure
Sudakov Representation of the Cachazo-He-Yuan Scattering Equations
  Formalism

We show that the use of Sudakov variables greatly simplifies the study of the
solutions to the scattering equations in the Cachazo-He-Yuan formalism. We work
in the center-of-mass frame for the two incoming particles, which partially
fixes the SL(2,C) redundancy in the integrand defining the scattering
amplitudes, the remaining freedom translates into a global shift in the
azimuthal angle of the outgoing particles. Studying four- and five-particle
amplitudes, we see how an appropriate choice of this phase allows for algebraic
simplifications when finding solutions to the scattering equations, as well as
in the expression of the scattering amplitudes in terms of the locations of the
punctures in the sphere. These punctures themselves are remarkably simple
functions of the Sudakov parameters.Comment: 30 pages, 4 figures. Typos removed. Final version published in JHE
Rindler Fluid with Weak Momentum Relaxation

We realize the weak momentum relaxation in Rindler fluid, which lives on the
time-like cutoff surface in an accelerating frame of flat spacetime. The
translational invariance is broken by massless scalar fields with weak
strength. Both of the Ward identity and the momentum relaxation rate of Rindler
fluid are obtained, with higher order correction in terms of the strength of
momentum relaxation. The Rindler fluid with momentum relaxation could also be
approached through the near horizon limit of cutoff AdS fluid with momentum
relaxation, which lives on a finite time-like cutoff surface in Anti-de
Sitter(AdS) spacetime, and further could be connected with the holographic
conformal fluid living on AdS boundary at infinity. Thus, in the holographic
Wilson renormalization group flow of the fluid/gravity correspondence with
momentum relaxation, the Rindler fluid can be considered as the Infrared
Radiation(IR) fixed point, and the holographic conformal fluid plays the role
of the ultraviolet(UV) fixed point.Comment: 23 pages. Matches the published version, main results are summarized

Spectrum universality properties of holographic Chern-Simons theories

We give a master formula for the spin-2 spectrum of a class of
three-dimensional Chern-Simons theories at large $N$, with flavour group
containing SU(3), that arise as infrared fixed points of the D2-brane
worldvolume field theory and have AdS$_4$ duals in massive type IIA
supergravity. We use this formula to compute the spin-2 spectrum of the
individual theories, discuss its supermultiplet structure and, for an ${\cal
N}=2$ theory in this class, the spectrum of protected operators with spin 2. We
also show that the trace of the Kaluza-Klein graviton mass matrix on the dual
AdS$_4$ solutions enjoys certain universality properties. These are shown to
relate the class of AdS$_4$ massive IIA solutions under consideration to a
similar class of AdS$_4$ solutions of $D=11$ supergravity with the same
symmetries. Finally, for the ${\cal N}=2$ AdS$_4$ solution in this class, we
study the entire spectrum at lowest Kaluza-Klein level and relate it to an
analogue solution in $D=11$ supergravity.Comment: 35 pages, 4 tables. v2: Reference added, minor typos corrected and a

On the Local Frame in Nonlinear Higher-Spin Equations

Properties of the resolution operator ${\rm d}_{loc}^*$ in higher-spin
equations, that leads to local current interactions at the cubic order and
minimally nonlocal higher-order corrections, are formulated in terms of the
condition on the class of master fields of higher-spin theory that restricts
both the dependence on the spinor $Y$, $Z$ variables and on the contractions of
indices between the constituent fields in bilinear terms. The Green function in
the sector of zero-forms is found for the case of constituent fields carrying
helicities of opposite signs. It is shown that the local resolution ${\rm
d}_{loc}^*$ differs from the conventional De Rham resolution ${\rm d}_Z^*$ by a
non-local shift.Comment: 26 pages; V2: typos corrected, version published in JHE
Contrasting SYK-like Models

We contrast some aspects of various SYK-like models with large-$N$ melonic
behavior. First, we note that ungauged tensor models can exhibit symmetry
breaking, even though these are 0+1 dimensional theories. Related to this, we
show that when gauged, some of them admit no singlets, and are anomalous. The
uncolored Majorana tensor model with even $N$ is a simple case where gauge
singlets can exist in the spectrum. We outline a strategy for solving for the
singlet spectrum, taking advantage of the results in arXiv:1706.05364, and
reproduce the singlet states expected in $N=2$. In the second part of the
paper, we contrast the random matrix aspects of some ungauged tensor models,
the original SYK model, and a model due to Gross and Rosenhaus. The latter,
even though disorder averaged, shows parallels with the Gurau-Witten model. In
particular, the two models fall into identical Andreev ensembles as a function
of $N$. In an appendix, we contrast the (expected) spectra of AdS$_2$ quantum
gravity, SYK and SYK-like tensor models, and the zeros of the Riemann Zeta
function.Comment: 45 pages, 17 figures; v2: minor improvements and rearrangements, refs
