Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Riku Ishikawa, Hitoshi Murayama, Shota Saito, , | Summary: We classify “truly confining” (t-confining) supersymmetric gauge theories, in which no center charges can be screened, and Wilson loops in the fundamental representation are therefore expected to exhibit an area law. In all cases, we identify the condensation […]
Kavli Affiliate: Tomotake Matsumura | First 5 Authors: Kosuke Aizawa, Ryosuke Akizawa, Scott Cray, Shaul Hanany, Shotaro Kawano | Summary: We present designs and fabrication of sub-wavelength anti-reflection (AR) structures on alumina for infrared absorptive filters with passbands near 30, 125, and 250 GHz. These bands are widely used by ground-based instruments measuring the cosmic […]
Kavli Affiliate: John D. Silverman | First 5 Authors: Zhaoxuan Liu, John D. Silverman, Emanuele Daddi, Boris S. Kalita, Annagrazia Puglisi | Summary: We present high-resolution and spatially-matched observations with JWST and ALMA of a starburst galaxy (PACS-830) at $z=1.46$. The NIRCam observations mainly trace the stellar light while the CO ($J$=5–4) observations map the […]
Kavli Affiliate: Misao Sasaki | First 5 Authors: Xinpeng Wang, Misao Sasaki, Ying-li Zhang, , | Summary: We report a novel mechanism where two families of primordial black holes (PBHs) may form at nearly the same comoving scales but at two different epochs. It is realized in two-stage inflation where a non-inflationary stage is sandwiched […]
Kavli Affiliate: Masahiro Takada | First 5 Authors: Ryo Terasawa, Masahiro Takada, Toshiki Kurita, Sunao Sugiyama, | Summary: The $S_8$ value inferred from the Subaru Hyper Suprime-Cam (HSC) Year 3 cosmic shear data, under the assumption of the flat $Lambda$CDM model, is 2-3$sigma$ lower than that inferred from observations of the early-time universe, such as […]
Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Tony Gherghetta, Hitoshi Murayama, Pablo Quílez, , | Summary: We present a composite QCD axion model where the Peccei–Quinn (PQ) symmetry emerges as a high-quality, accidental symmetry. The axion potential is only modified by eight-fermion, dimension 12 operators, which if present at the Planck scale, allow for […]
Kavli Affiliate: Tom Melia | First 5 Authors: David E. Kaplan, Tom Melia, Surjeet Rajendran, , | Summary: Three possible strategies have been advocated to solve the strong CP problem. The first is the axion, a dynamical mechanism that relaxes any initial value of the CP violating angle $bar{theta}$ to zero. The second is the […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Saghar S. Hosseini, Yuji Tachikawa, Hao Y. Zhang, , | Summary: We revisit the issue of how the perturbative and global fermion anomaly of Type I string theory in ten dimensions is cancelled by the Green-Schwarz mechanism using the RR fields. This will be done by realising […]
Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Andrew Goh, Hitoshi Murayama, Gup Singh, Bethany Suter, Jason Wong | Summary: We present exact non-perturbative solutions to chiral gauge theories based on the $E_6$ gauge group and several matter fermions in the fundamental $bf{27}$-dimensional representation. They are obtained when supersymmetric versions are perturbed by small supersymmetry […]
