Abstract , using events with a single top quark and an energetic$$\chi $$ W boson. The analysis is based on proton–proton collision data collected with the ATLAS experiment at 13 TeV during LHC Run 2 (2015–2018), corresponding to an integrated luminosity of 139 fb$$\sqrt{s}=$$ . The search considers final states with zero or one charged lepton (electron or muon), at least one$$^{-1}$$ b -jet and large missing transverse momentum. In addition, a result from a previous search considering two-charged-lepton final states is included in the interpretation of the results. The data are found to be in good agreement with the Standard Model predictions and the results are interpreted in terms of 95% confidence-level exclusion limits in the context of a class of dark matter models involving an extended two-Higgs-doublet sector together with a pseudoscalar mediator particle. The search is particularly sensitive to on-shell production of the charged Higgs boson state, , arising from the two-Higgs-doublet mixing, and its semi-invisible decays via the mediator particle,$$H^{\pm }$$ a : . Signal models with$$H^{\pm } \rightarrow W^\pm a (\rightarrow \chi \chi )$$ masses up to 1.5 TeV and$$H^{\pm }$$ a masses up to 350 GeV are excluded assuming a value of 1. For masses of$$\tan \beta $$ a of 150 (250) GeV, values up to 2 are excluded for$$\tan \beta $$ masses between 200 (400) GeV and 1.5 TeV. Signals with$$H^{\pm }$$ values between 20 and 30 are excluded for$$\tan \beta $$ masses between 500 and 800 GeV.$$H^{\pm }$$ -
A bstract Several extensions of the Standard Model predict the production of dark matter particles at the LHC. A search for dark matter particles produced in association with a dark Higgs boson decaying into
W +W − in the final states with$$ {\ell}^{\pm}\nu q{\overline{q}}^{\prime }, $$ ℓ =e, μ is presented. This analysis uses 139 fb− 1ofpp collisions recorded by the ATLAS detector at a centre-of-mass energy of 13 TeV. TheW ± → decays are reconstructed from pairs of calorimeter-measured jets or from track-assisted reclustered jets, a technique aimed at resolving the dense topology from a pair of boosted quarks using jets in the calorimeter and tracking information. The observed data are found to agree with Standard Model predictions. Scenarios with dark Higgs boson masses ranging between 140 and 390 GeV are excluded.$$ q\overline{q^{\prime }} $$ -
Abstract In a Merlin–Arthur proof system, the proof verifier (Arthur) accepts valid proofs (from Merlin) with probability 1, and rejects invalid proofs with probability arbitrarily close to 1. The running time of such a system is defined to be the length of Merlin’s proof plus the running time of Arthur. We provide new Merlin–Arthur proof systems for some key problems in fine-grained complexity. In several cases our proof systems have optimal running time. Our main results include:
Certifying that a list of
n integers has no 3-SUM solution can be done in Merlin–Arthur time . Previously, Carmosino et al. [ITCS 2016] showed that the problem has a nondeterministic algorithm running in$$\tilde{O}(n)$$ time (that is, there is a proof system with proofs of length$$\tilde{O}(n^{1.5})$$ and a deterministic verifier running in$$\tilde{O}(n^{1.5})$$ time).$$\tilde{O}(n^{1.5})$$ Counting the number of
k -cliques with total edge weight equal to zero in ann -node graph can be done in Merlin–Arthur time (where$${\tilde{O}}(n^{\lceil k/2\rceil })$$ ). For odd$$k\ge 3$$ k , this bound can be further improved for sparse graphs: for example, counting the number of zero-weight triangles in anm -edge graph can be done in Merlin–Arthur time . Previous Merlin–Arthur protocols by Williams [CCC’16] and Björklund and Kaski [PODC’16] could only count$${\tilde{O}}(m)$$ k -cliques in unweighted graphs, and had worse running times for smallk .Computing the All-Pairs Shortest Distances matrix for an
n -node graph can be done in Merlin–Arthur time . Note this is optimal, as the matrix can have$$\tilde{O}(n^2)$$ nonzero entries in general. Previously, Carmosino et al. [ITCS 2016] showed that this problem has an$$\Omega (n^2)$$ nondeterministic time algorithm.$$\tilde{O}(n^{2.94})$$ Certifying that an
n -variablek -CNF is unsatisfiable can be done in Merlin–Arthur time . We also observe an algebrization barrier for the previous$$2^{n/2 - n/O(k)}$$ -time Merlin–Arthur protocol of R. Williams [CCC’16] for$$2^{n/2}\cdot \textrm{poly}(n)$$ SAT: in particular, his protocol algebrizes, and we observe there is no algebrizing protocol for$$\#$$ k -UNSAT running in time. Therefore we have to exploit non-algebrizing properties to obtain our new protocol.$$2^{n/2}/n^{\omega (1)}$$ Certifying a Quantified Boolean Formula is true can be done in Merlin–Arthur time
. Previously, the only nontrivial result known along these lines was an Arthur–Merlin–Arthur protocol (where Merlin’s proof depends on some of Arthur’s coins) running in$$2^{4n/5}\cdot \textrm{poly}(n)$$ time.$$2^{2n/3}\cdot \textrm{poly}(n)$$ n integers can be done in Merlin–Arthur time , improving on the previous best protocol by Nederlof [IPL 2017] which took$$2^{n/3}\cdot \textrm{poly}(n)$$ time.$$2^{0.49991n}\cdot \textrm{poly}(n)$$ -
Abstract We present a proof of concept for a spectrally selective thermal mid-IR source based on nanopatterned graphene (NPG) with a typical mobility of CVD-grown graphene (up to 3000
), ensuring scalability to large areas. For that, we solve the electrostatic problem of a conducting hyperboloid with an elliptical wormhole in the presence of an$$\hbox {cm}^2\,\hbox {V}^{-1}\,\hbox {s}^{-1}$$ in-plane electric field. The localized surface plasmons (LSPs) on the NPG sheet, partially hybridized with graphene phonons and surface phonons of the neighboring materials, allow for the control and tuning of the thermal emission spectrum in the wavelength regime from to 12$$\lambda =3$$ m by adjusting the size of and distance between the circular holes in a hexagonal or square lattice structure. Most importantly, the LSPs along with an optical cavity increase the emittance of graphene from about 2.3% for pristine graphene to 80% for NPG, thereby outperforming state-of-the-art pristine graphene light sources operating in the near-infrared by at least a factor of 100. According to our COMSOL calculations, a maximum emission power per area of$$\upmu$$ W/$$11\times 10^3$$ at$$\hbox {m}^2$$ K for a bias voltage of$$T=2000$$ V is achieved by controlling the temperature of the hot electrons through the Joule heating. By generalizing Planck’s theory to any grey body and deriving the completely general nonlocal fluctuation-dissipation theorem with nonlocal response of surface plasmons in the random phase approximation, we show that the coherence length of the graphene plasmons and the thermally emitted photons can be as large as 13$$V=23$$ m and 150$$\upmu$$ m, respectively, providing the opportunity to create phased arrays made of nanoantennas represented by the holes in NPG. The spatial phase variation of the coherence allows for beamsteering of the thermal emission in the range between$$\upmu$$ and$$12^\circ$$ by tuning the Fermi energy between$$80^\circ$$ eV and$$E_F=1.0$$ eV through the gate voltage. Our analysis of the nonlocal hydrodynamic response leads to the conjecture that the diffusion length and viscosity in graphene are frequency-dependent. Using finite-difference time domain calculations, coupled mode theory, and RPA, we develop the model of a mid-IR light source based on NPG, which will pave the way to graphene-based optical mid-IR communication, mid-IR color displays, mid-IR spectroscopy, and virus detection.$$E_F=0.25$$ -
Abstract The possibility in supersymmetric scenarios that the dark matter candidate is a Higgsino-like neutralino means that its production can be associated with Higgs bosons. Taking advantage of this fact, we propose a LHC search strategy for gluinos with
leptons in the final state, coming from the decay of a Higgs boson. We consider the strong production of a pair of gluinos, one of which decays into the Higgsino plus jets while the other decays into the bino plus jets. In turn, this bino decays into the Higgsino plus a Higgs boson which finally decays into a$$\tau $$ -lepton pair. Therefore, the experimental signature under study consists of 4 jets, 2$$\tau $$ leptons, and a large amount of missing transverse energy. This work represents a proof of principle of a search that is sensitive to a spectrum such that the gluino does not directly decay to the dark matter candidate but to an intermediate electroweakino that then produces Higgs bosons in its subsequent decay. Our cut-based search strategy allows us to reach, for a LHC center-of-mass energy of 14 TeV and a total integrated luminosity of 1 ab$$\tau $$ , significances of up to 2 standard deviations, considering systematic uncertainties in the SM background of 30%. The projections for 3 ab$$^{-1}$$ are encouraging, with significances at the evidence level, which in more optimistic experimental scenarios could exceed 4 standard deviations.$$^{-1}$$
