Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Ryuichiro Kitano, Ryutaro Matsudo, Norikazu Yamada, Masahito Yamazaki, | Summary: We propose a subvolume method to study the $theta$ dependence of the free energy density of the four-dimensional SU($N$) Yang-Mills theory on the lattice. As an attempt, the method is first applied to SU(2) Yang-Mills theory at […]
Kavli Affiliate: Shigeki Matsumoto | First 5 Authors: Shun-ichi Horigome, Taisuke Katayose, Shigeki Matsumoto, Ipsita Saha, | Summary: The leptophilic weakly interacting massive particle (WIMP) is realized in a minimal renormalizable model scenario where scalar mediators with lepton number establish the WIMP interaction with the standard model (SM) leptons. We perform a comprehensive analysis for […]
Kavli Affiliate: Paul L. Schechter | First 5 Authors: Richard Luhtaru, Paul L. Schechter, Kaylee M. de Soto, , | Summary: Among known strongly lensed quasar systems, ~25% have gravitational potentials sufficiently flat (and sources sufficiently well aligned) to produce four images rather than two. The projected flattening of the lensing galaxy and tides from […]
Kavli Affiliate: C. M. Ignarra | First 5 Authors: D. S. Akerib, S. Alsum, H. M. Araújo, X. Bai, J. Balajthy | Summary: We report here the results of an Effective Field Theory (EFT) WIMP search analysis using LUX data. We build upon previous LUX analyses by extending the search window to include nuclear recoil […]
Kavli Affiliate: Giorgio Gratta | First 5 Authors: Charles P. Blakemore, Alexander Fieguth, Akio Kawasaki, Nadav Priel, Denzal Martin | Summary: We report on a search for non-Newtonian forces that couple to mass, with a characteristic scale of ${sim}10~mu$m, using an optically levitated microsphere as a precision force sensor. A silica microsphere trapped in an […]
Kavli Affiliate: Alan M. Levine | First 5 Authors: Rebekah I. Dawson, Chelsea X. Huang, Rafael Brahm, Karen A. Collins, Melissa J. Hobson | Summary: TOI-216 hosts a pair of warm, large exoplanets discovered by the TESS Mission. These planets were found to be in or near the 2:1 resonance, and both of them exhibit […]
Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Angelo Caravano, Eiichiro Komatsu, Kaloian D. Lozanov, Jochen Weller, | Summary: The scalar field theory of cosmological inflation constitutes nowadays one of the preferred scenarios for the physics of the early universe. In this paper we aim at studying the inflationary universe making use of a numerical […]
Kavli Affiliate: Gabor Furesz | First 5 Authors: Benjamin M. Tofflemire, Aaron C. Rizzuto, Elisabeth R. Newton, Adam L. Kraus, Andrew W. Mann | Summary: The detection and characterization of young planetary systems offers a direct path to study the processes that shape planet evolution. We report on the discovery of a sub-Neptune-size planet orbiting […]
Kavli Affiliate: Alan M. Levine | First 5 Authors: Elisabeth R. Newton, Andrew W. Mann, Adam L. Kraus, John H. Livingston, Andrew Vanderburg | Summary: Young exoplanets can offer insight into the evolution of planetary atmospheres, compositions, and architectures. We present the discovery of the young planetary system TOI 451 (TIC 257605131, Gaia DR2 4844691297067063424). […]
Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Oscar Macias, Harm van Leijen, Deheng Song, Shin’ichiro Ando, Shunsaku Horiuchi | Summary: The leading explanation of the $textit{Fermi}$ Galactic center $gamma$-ray excess is the extended emission from a unresolved population of millisecond pulsars (MSPs) in the Galactic bulge. Such a population would, along with the prompt […]
