Early Release Science of the exoplanet WASP-39b with JWST NIRSpec PRISM
(Nature Research, 2023-01-09)Transmission spectroscopy1,2,3 of exoplanets has revealed signatures of water vapour, aerosols and alkali metals in a few dozen exoplanet atmospheres4,5. However, these previous inferences with the Hubble and Spitzer Space ... -
Early Release Science of the exoplanet WASP-39b with JWST NIRCam
(Nature Research, 2023-01-09)Measuring the metallicity and carbon-to-oxygen (C/O) ratio in exoplanet atmospheres is a fundamental step towards constraining the dominant chemical processes at work and, if in equilibrium, revealing planet formation ... -
Mid-infrared interference coatings with excess optical loss below 10 ppm
(Optica, 2021-05-14)Low excess optical loss, combined absorption and scatter loss, is a key performance metric for any high-reflectance coating technology and is currently one of the main limiting factors for the application of optical ... -
Fourier Analysis of Magnetic Fields in the Ionosphere of Mars
(2023-02-11)The two main sources of magnetic field for the Martian ionosphere are the solar wind magnetic fields (i.e., the interplanetary magnetic field), and, particularly in the southern hemisphere, remnant crustal magnetization. ... -
Exclusive Four-pion Photoproduction in Ultra-peripheral Heavy-ion Collisions at RHIC and LHC Energies
(Polish Academy of Arts and Sciences, 2020-01-07)We study the photoproduction of exclusive 2π+2π− mesons in ultra-peripheral heavy-ion collisions at the RHIC and LHC energies. Predictions in photon–nucleus interactions are calculated for various resonances at central and ... -
Search for light pseudoscalar boson pairs produced from decays of the 125 GeV Higgs boson in final states with two muons and two nearby tracks in pp collisions at √s = 13 TeV
(Elsevier, 2020-01-10)A search is presented for pairs of light pseudoscalar bosons, in the mass range from 4 to 15 GeV, produced from decays of the 125 GeV Higgs boson. The decay modes considered are final states that arise when one of the ... -
Elastic differential cross-section dσ/dt at s√=2.76 TeV and implications on the existence of a colourless C-odd three-gluon compound state
(SpringerOpen, 2020-02-05)The proton–proton elastic differential cross section dσ/dt has been measured by the TOTEM experiment at s√=2.76 TeV energy with β∗=11 m beam optics. The Roman Pots were inserted to 13 times the transverse beam size from ... -
Exclusive Diffraction at the LHC On behalf of the ATLAS, LHCb, CMS and TOTEM experiments
(EDP Open, 2020-06-16)In this report, we describe the most recent results on exclusive diffraction from the ATLAS, CMS, LHCb, TOTEM experiments at the LHC concerning exclusive pions, J/Ψ, Ψ(2S ), dilepton, diphoton, WW productions and prospects ... -
Probing BFKL dynamics at hadronic colliders in jet gap jet events
(EDP Open, 2020-06-16)In this report, we give the Balitsky Fadin Kuraev Lipton formalism for jet gap jet events at hadronic colliders. We also discuss the case where in addition at least one proton is intact in the final state in diffractive events. -
Timing information at HL-LHC: complete determination of masses of dark matter and long lived particle
(Springer, 2020-03-24)A long-standing kinematic challenge in data analysis at hadron colliders is the determination of the masses of invisible particles. This issue is particularly relevant in searches for evidence of dark matter production, ... -
First-principles surface energies for monoclinic Ga2O3 and Al2O3 and consequences for cracking of (AlxGa1−x)2O3
(American Institute of Physics, 2020-09-09)Crack formation limits the growth of (AlxGa1−x)2O3 epitaxial films on Ga2O3 substrates. We employ first-principles calculations to determine the brittle fracture toughness of such films for three growth orientations of the ... -
First-principles calculations of hyperfine interaction, binding energy, and quadrupole coupling for shallow donors in silicon
(Nature Research, 2020-11-27)Spin qubits based on shallow donors in silicon are a promising quantum information technology with enormous potential scalability due to the existence of robust silicon-processing infrastructure. However, the most accurate ... -
Measurement of tt¯ normalised multi-differential cross sections in pp collisions at √s=13TeV, and simultaneous determination of the strong coupling strength, top quark pole mass, and parton distribution functions
(SpringerOpen, 2020-07-22)Normalised multi-differential cross sections for top quark pair (tt¯) production are measured in proton-proton collisions at a centre-of-mass energy of 13TeV using events containing two oppositely charged leptons. The ... -
Remodeler Catalyzed Nucleosome Repositioning: Influence of Structure and Stability
(MDPI, 2020-12-23)The packaging of the eukaryotic genome into chromatin regulates the storage of genetic information, including the access of the cell’s DNA metabolism machinery. Indeed, since the processes of DNA replication, translation, ... -
Reinterpretation of LHC Results for New Physics: Status and recommendations after Run 2
(SciPost, 2020-08-21)We report on the status of efforts to improve the reinterpretation of searches and measurements at the LHC in terms of models for new physics, in the context of the LHC Reinterpretation Forum. We detail current experimental ... -
The motivation and status of two-body resonance decays after the LHC Run 2 and beyond
(Springer, 2020-04-06)Searching for two-body resonance decays is a central component of the high energy physics energy frontier research program. While many of the possibilities are covered when the two bodies are Standard Model (SM) particles, ... -
Search for physics beyond the standard model in events with jets and two same-sign or at least three charged leptons in proton-proton collisions at √s=13TeV
