Combined analysis of Belle and Belle II data to determine the CKM angle $ φ_{3} $ using $B^+ to D(K_{S}^0 h^- h^+) h^+$ decays

Posted by klaurent Tokyo

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle, Belle II Collaborations, :, F. Abudinén, L. Aggarwal | Summary: We present a measurement of the Cabibbo-Kobayashi-Maskawa unitarity triangle angle $ phi_{3} $ (also known as~$gamma$) using a model-independent Dalitz plot analysis of linebreak $B^+to Dleft(K_{S}^{0}h^{+}h^{-}right)h^+$, where $D$ is either a $D^0$ or $bar{D}{}^0$ meson and […]

What drives the scatter of local star-forming galaxies in the BPT diagrams? A Machine Learning based analysis

Posted by klaurent Cambridge

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Mirko Curti, Connor Hayden-Pawson, Roberto Maiolino, Francesco Belfiore, Filippo Mannucci | Summary: We investigate which physical properties are most predictive of the position of local star forming galaxies on the BPT diagrams, by means of different Machine Learning (ML) algorithms. Exploiting the large statistics from the Sloan […]

Unified Description of Tunneling Transport in Ultracold Atomic Gases

Posted by klaurent UCAS

Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Hiroyuki Tajima, Daigo Oue, Mamoru Matsuo, , | Summary: We derive tunneling Hamiltonians from a microscopic model of ultracold atoms separated by an external potential barrier. Not only usual one-body tunneling but also pair- and spin-tunneling processes naturally arise from a well-known microscopic model without any empirical […]

Multi-Particle Tunneling Transport at Strongly-Correlated Interfaces

Posted by klaurent UCAS

Kavli Affiliate: Mamoru Matsuo | First 5 Authors: Hiroyuki Tajima, Daigo Oue, Mamoru Matsuo, , | Summary: We elucidate the multi-particle transport of pair- and spin-tunnelings in strongly correlated interfaces. Not only usual single-particle tunneling but also interaction-induced multi-particle tunneling processes naturally arise from a conventional microscopic model without any empirical parameters, through the overlap […]

Density of States Prediction for Materials Discovery via Contrastive Learning from Probabilistic Embeddings

Posted by klaurent Berkeley

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Shufeng Kong, Francesco Ricci, Dan Guevarra, Jeffrey B. Neaton, Carla P. Gomes | Summary: Machine learning for materials discovery has largely focused on predicting an individual scalar rather than multiple related properties, where spectral properties are an important example. Fundamental spectral properties include the phonon density […]

On games and simulators as a platform for development of artificial intelligence for command and control

Posted by klaurent MIT

Kavli Affiliate: John Richardson | First 5 Authors: Vinicius G. Goecks, Nicholas Waytowich, Derrik E. Asher, Song Jun Park, Mark Mittrick | Summary: Games and simulators can be a valuable platform to execute complex multi-agent, multiplayer, imperfect information scenarios with significant parallels to military applications: multiple participants manage resources and make decisions that command assets […]

Possible X-ray Quasi-Periodic Eruptions in a Tidal Disruption Event Candidate

Posted by klaurent MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Joheen Chakraborty, Erin Kara, Megan Masterson, Margherita Giustini, Giovanni Miniutti | Summary: X-ray Quasi-Periodic Eruptions (QPEs) are a recently discovered phenomenon associated with supermassive black holes at the centers of galaxies. They are high amplitude soft X-ray flares that recur on timescales of hours, but what causes […]
