Heavy Quark State Production via p-p and O-O Collisions
Here we have considered $J/Ψ$ is a normal charmonium meson, while $Ψ(2S)$ is a mixed hybrid charmonium meson. Similarly $Υ(1S)$ and$Υ(2S)$ are normal upsilon mesons, while $Υ(3S)$ is a mixed hybrid upsilon meson. We discuss the differential rapidity cross sections for $J/Ψ$, $Ψ(2S)$, $Υ(1S)$, $Υ(2S)$, $Υ(3S)$ production via p-p, and O-O collisions at proton-proton energy $\equiv \sqrt{s_{pp}}$= 5.44 TeV. The rapidity taken for the present study goes from y=-1 to 1.

AURA: Agentic Upskilling via Reinforced Abstractions
We study the combinatorial explosion involved in translating high-level task prompts into deployable control policies for agile robots through multi-stage reinforcement learning. We introduce AURA (Agentic Upskilling via Reinforced Abstractions), a schema-centric curriculum RL framework that leverages Large Language Models (LLMs) as autonomous designers of multi-stage curricula. AURA transforms user prompts into YAML workflows that encode full reward functions, domain randomization strategies, …

Search for Pcs(4459) and Pcs(4338) in Upsilon(1S,2S) inclusive decays at Belle
Using data samples of 102 million Upsilon(1S) events and 158 million Upsilon(2S) events collected by the Belle detector at the KEKB asymmetric-energy $e^+e^-$ collider, we search for [udsccbar] pentaquark states decaying to Jpsi Lambda. Using the first observations of Upsilon(1S, 2S) inclusive decays to Jpsi Lambda, we find evidence of the P_ccbars(4459)0 state with a local significance of 3.3 standard deviations, including statistical and systematic uncertainties. We measure the mass and width…

A hierarchical approach for multicontinuum homogenization in high contrast media
A recently developed upscaling technique, the multicontinuum homogenization method, has gained significant attention for its effectiveness in modeling complex multiscale systems. This method defines multiple continua based on distinct physical properties and solves a series of constrained cell problems to capture localized information for each continuum. However, solving all these cell problems on very fine grids at every macroscopic point is computationally expensive, which is a common limitat…
