Boosting Higgs pair production in the bbˉbbˉb\bar{b}b\bar{b} final state with multivariate techniques

The measurement of Higgs pair production will be a cornerstone of the LHC program in the coming years. Double Higgs production provides a crucial window upon the mechanism of electroweak symmetry breaking and has a unique sensitivity to the Higgs trilinear coupling. We study the feasibility of a measurement of Higgs pair production in the $b\bar{b}b\bar{b}$ final state at the LHC. Our analysis is based on a combination of traditional cut-based methods with state-of-the-art multivariate techniques. We account for all relevant backgrounds, including the contributions from light and charm jet mis-identification, which are ultimately comparable in size to the irreducible $4b$ QCD background. We demonstrate the robustness of our analysis strategy in a high pileup environment. For an integrated luminosity of $\mathcal{L}=3$ ab$^{-1}$, a signal significance of $S/\sqrt{B}\simeq 3$ is obtained, indicating that the $b\bar{b}b\bar{b}$ final state alone could allow for the observation of double Higgs production at the High-Luminosity LHC.Comment: 47 pages, 22 figures. v2: updated references, added comparison of post-MVA kinematic distributions. v3: matches published version in EPJ

Coherent vibrations of submicron spherical gold shells in a photonic crystal

Coherent acoustic radial oscillations of thin spherical gold shells of submicron diameter excited by an ultrashort optical pulse are observed in the form of pronounced modulations of the transient reflectivity on a subnanosecond time scale. Strong acousto-optical coupling in a photonic crystal enhances the modulation of the transient reflectivity up to 4%. The frequency of these oscillations is demonstrated to be in good agreement with Lamb theory of free gold shells.Comment: Error in Eqs.2 and 3 corrected; Tabl. I corrected; Fig.1 revised; a model that explains the dependence of the oscillation amplitude of the transient reflectivity with wavelength adde

Low-Reynolds-number gravity-driven migration and deformation of bubbles near a free surface

International audienceWe investigate numerically the axisymmetric migration of bubbles toward a free surface, using a boundary-integral technique. Our careful numerical implementation allows to study the bubble(s) deformation and film drainage; it is benchmarked against several tests. The rise of one bubble toward a free surface is studied and the computed bubble shape compared with the results of Princen [J. Colloid Interface Sci. 18, 178 (1963)]. The liquid film between the bubble and the free surface is found to drain exponentially in time in full agreement with the experimental work of Debre'geas et al. [Science 279, 1704 (1998)]. Our numerical results also cast some light on the role played by the deformation of the fluid interfaces and it turns out that for weakly deformed interfaces (high surface tension or a tiny bubble) the film drainage is faster than for a large fluid deformation. By introducing one or two additional bubble(s) below the first one, we examine to which extent the previous trends are affected by bubble-bubble interactions. For instance, for a 2-bubble chain, decreasing the bubblebubble separation increases the deformation of the last bubble in the chain. Finally, the exponential drainage of the film between the free surface and the closest bubble is preserved, yet the drainage is enhanced

Siting prisons, sighting communities: geographies of objection in a planning process

This paper reviews the planning process for a Scottish prison located near a former mining village. Analysing the letters of objection submitted by residents offers an opportunity to explore local views about prison and community and to relate these to the unique social and spatial history of the area. The planning process itself structured how residents were able to express themselves and defined what counted as a relevant objection. After deconstructing this process, the paper then restores and uses as a framework for analysis three geographies of objection stripped from local responses to the development proposal: the emotional, temporal, and spatial. Emotional expressions of objection added intensity and gave meaning to claims about the historical decline of the region and also conveyed a deep sense of the proposed building site as a lived space. Particular grounds of opposition—over fear of strangers, the fragility of a local orchid, and the pollution from mining—provide an opportunity to explore the complex nature of place meaning and community identity, ultimately leading to a conclusion that the meaning of place is always in flux. The paper argues that Simmel’s classic concept of the stranger, as the outsider who comes to stay, offers a useful analytic in understanding how the quality of proximal remoteness that prisons and other unwanted developments constitute participates in a constantly evolving sense of the local

Bed Site Selection of Fawn Pronghorn in Custer State Park, South Dakota

We evaluated pronghorn (Antilocapra americana) fawn bedding site characteristics on a prairie and ponderosa pine (Pinus ponderosa) landscape interface in Custer State Park, South Dakota. We radio-marked 16 adult female pronghorn and collected bed site information from their fawns during 2007~2008. We compared bed site selection with random sites (n = 74) during 2 periods; the early hiding phase when fawns were 1 ~28 days of age (n = 23 bed sites) and the later group phase when fawns were 29~60 days of age (n = 52 bed sites). During the hiding phase fawns selected dry prairie-seminatural mixed grassland at the course-scale level; group phase fawns selected prairie dog (Cynomys ludoviciana) dominated grasslands and dry prairie-seminatural mixed grassland at the course-scale. Evaluation at the fine-scale indicated fawns during the group phase period selected bed sites that had greater forb cover and overs tory canopy cover of ponderosa pine trees compared to random sites. Management activities that promote a dynamic grassland ecosystem with patches of forb cover may enhance resources selected as bedding habitat by pronghorn fawns during the group phase period

Nanoantenna-enhanced ultrafast nonlinear spectroscopy of a single gold nanoparticle

Optical nanoantennas are a novel tool to investigate previously unattainable dimensions in the nanocosmos. Just like their radio-frequency equivalents, nanoantennas enhance the light-matter interaction in their feed gap. Antenna enhancement of small signals promises to open a new regime in linear and nonlinear spectroscopy on the nanoscale. Without antennas especially the nonlinear spectroscopy of single nanoobjects is very demanding. Here, we present for the first time antenna-enhanced ultrafast nonlinear optical spectroscopy. In particular, we utilize the antenna to determine the nonlinear transient absorption signal of a single gold nanoparticle caused by mechanical breathing oscillations. We increase the signal amplitude by an order of magnitude which is in good agreement with our analytical and numerical models. Our method will find applications in linear and nonlinear spectroscopy of nanoobjects, ranging from single protein binding events via nonlinear tensor elements to the limits of continuum mechanics

Leveraging sponsorship to achieve consumer relationship objectives through the creation of ‘marketing spaces’: An exploratory study

This paper explores the emergence of sponsorship-linked events as a strategy to leverage relational outcomes through sponsorship investment. The growing use of sponsorship-linked events reinforces the need to understand the potential of such leverage strategies, thus the findings contribute to the body of literature on effective sponsorship practices. Findings from semi-structured interviews with Sponsorship and Marketing Managers suggest a shifting orientation among sponsors towards the pursuit of relational objectives. The privileged access to consumers afforded through sponsorship allows sponsors to manufacture opportunities to create intimacy with customers through sponsorship-linked events in relaxed, comfortable environments; thus sponsorship-linked events are positioned as a rich environment to add value to consumer–brand interactions and achieve relational objectives. Hosting specifically designed events affords sponsors an increased modicum of control over consumer–brand experiences in sponsorship environments characterised by a lack of control over sponsored property actions. However, this control may be eroded by social media technologies, which facilitate consumer–consumer communication around sponsorship-linked events. Social media, however, is proposed as a useful tool to elicit consumer feedback, addressing the misalignment between current sponsorship evaluation practices and emergent relational objectives revealed in the empirical findings. Therefore, successfully activating the sponsorship-linked marketing space demands an integrated and strategic approach
