Adiabatic Quantum Algorithm for Multijet Clustering in High Energy Physics
Diogo Pires, Yasser Omar, João Seixas
The currently predicted increase in computational demand for the upcoming High-Luminosity Large Hadron Collider (HL-LHC) event reconstruction, and in particular jet clustering, is…
Nuclear dependence of light neutral meson production in p-A collisions at 400 GeV with NA60
R. Arnaldi, K. Banicz, K. Borer +51
The NA60 experiment has studied low-mass muon pair production in proton-nucleus collisions with a system of Be, Cu, In, W, Pb and U targets, using a 400 GeV proton beam at the CERN…
Imaging neutron capture cross sections: i-TED proof-of-concept and future prospects based on Machine-Learning techniques
V. Babiano-Suárez, J. Lerendegui-Marco, J. Balibrea-Correa +132
i-TED is an innovative detection system which exploits Compton imaging techniques to achieve a superior signal-to-background ratio in () cross-section measurements using time-…
Variational preparation of finite-temperature states on a quantum computer
R. Sagastizabal, S. P. Premaratne, B. A. Klaver +13
The preparation of thermal equilibrium states is important for the simulation of condensed-matter and cosmology systems using a quantum computer. We present a method to prepare suc…
Characterizing entanglement using quantum discord over state extensions
Chunhe Xiong, Sunho Kim, Daowen Qiu +2
We propose a framework to characterize entanglement with quantum discord, both asymmetric and symmetric, over state extensions. In particular, we show that the minimal Bures distan…
The GRAVITY Young Stellar Object survey IV. The CO overtone emission in 51 Oph at sub-au scales
GRAVITY Collaboration, M. Koutoulaki, R. Garcia Lopez +69
51 Oph is a Herbig Ae/Be star that exhibits strong near-infrared CO ro-vibrational emission at 2.3 micron, most likely originating in the innermost regions of a circumstellar disc.…
The magic square of Lie groups: the case
Tevian Dray, John Huerta, Joshua Kincaid
A unified treatment of the analog of the Freudenthal-Tits magic square of Lie groups is given, providing an explicit representation in terms of matrix groups over comp…
Diquark Correlations in Hadron Physics: Origin, Impact and Evidence
M. Yu. Barabanov, M. A. Bedolla, W. K. Brooks +24
The last decade has seen a marked shift in how the internal structure of hadrons is understood. Modern experimental facilities, new theoretical techniques for the continuum bound-s…
Towards a more rigorous treatment of uncertainties on the velocity distribution of dark matter particles for capture in stars
José Lopes, Thomas Lacroix, Ilídio Lopes
Dark matter (DM) capture in stars offers a rich phenomenology that makes it possible to probe a wide variety of particle DM scenarios in diverse astrophysical environments. In spit…
Poynting vector, super-Poynting vector, and principal observers in electromagnetism and general relativity
Lode Wylleman, L. Filipe O. Costa, José Natário
In electromagnetism, the concept of Poynting vector as measured by an observer is well known. A mathematical analogue in general relativity is the super-Poynting vector of the Weyl…
Gravitational-wave constraints on the equatorial ellipticity of millisecond pulsars
The LIGO Scientific Collaboration, the Virgo Collaboration, R. Abbott +1333
We present a search for continuous gravitational waves from five radio pulsars, comprising three recycled pulsars (PSR J0437-4715, PSR J0711-6830, and PSR J0737-3039A) and two youn…
Test of the universality of and lepton couplings in -boson decays from events with the ATLAS detector
ATLAS Collaboration
The Standard Model of particle physics encapsulates our current best understanding of physics at the smallest scales. A fundamental axiom of this theory is the universality of the…
Chiral gravitational waves and primordial black holes in UV-protected Natural Inflation
Juan P. Beltrán Almeida, Nicolás Bernal, Dario Bettoni +1
We consider an UV-protected Natural Inflation scenario involving Chern-Simons-like interactions between the inflaton and some beyond the Standard Model gauge fields. The accelerate…
Potential gravitational-wave signatures of quantum gravity
Ivan Agullo, Vitor Cardoso, Adrian del Rio +2
We show that gravitational-wave astronomy has the potential to inform us on quantum aspects of black holes. Based on Bekenstein's quantization, we find that black hole area discret…
Graph integration of structured, semistructured and unstructured data for data journalism
Oana Balalau, Catarina Conceiç{ã}o, Helena Galhardas +4
Nowadays, journalism is facilitated by the existence of large amounts of digital data sources, including many Open Data ones. Such data sources are extremely heterogeneous, ranging…
Symmetric inclusion process with slow boundary: hydrodynamics and hydrostatics
Chiara Franceschini, Patrícia Gonçalves, Federico Sau
We study the hydrodynamic and hydrostatic limits of the one-dimensional open symmetric inclusion process with slow boundary. Depending on the value of the parameter tuning the inte…
Arithmetic of decay walls through continued fractions: a new exact dyon counting solution in CHL models
Gabriel Lopes Cardoso, Suresh Nampuri, Martí Rosselló
We use continued fractions to perform a systematic and explicit characterization of the decays of two-centred dyonic black holes in heterotic C…
Reconstruction of Events Recorded with the Surface Detector of the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Aab, P. Abreu +378
Cosmic rays arriving at Earth collide with the upper parts of the atmosphere, thereby inducing extensive air showers. When secondary particles from the cascade arrive at the ground…
