Search for dark matter production in association with bottom quarks and a lepton pair in proton-proton collisions at $s$ = 13 TeV

CMS Collaboration

A search is performed for dark matter produced in association with bottom quarks and a pair of electrons or muons in data collected with the CMS detector at the LHC, corresponding…

Observation of suppressed charged-particle production in ultrarelativistic oxygen-oxygen collisions

CMS Collaboration

A hot and dense state of nuclear matter, known as the quark-gluon plasma, is created in collisions of ultrarelativistic heavy nuclei. Highly energetic quarks and gluons, collective…

Observation of a threshold enhancement in the $I ¨ ^{+} I ¨ ^{-}$ spectrum in $I ¨ (3686) \to I ¨ ^{+} I ¨ ^{-} J / I ¨ $ decays

BESIII Collaboration, M. Ablikim, M. N. Achasov +677

The BESIII experiment analyzed over 2.7 billion ψ(3686) decays and observed a clear resonance-like enhancement near the π⁺π⁻ mass threshold in ψ(3686)→π⁺π⁻J/ψ decays, measuring its…

MiroThinker-1.7 & H1: Towards Heavy-Duty Research Agents via Verification

MiroMind Team, S. Bai, L. Bing +39

We present MiroThinker-1.7, a new research agent designed for complex long-horizon reasoning tasks. Building on this foundation, we further introduce MiroThinker-H1, which extends…

Observation of $I ¨ (3686) \to I^^{3} I^\cdot (1405)$ via $I^\cdot (1405) \to f_{0} (980) I ¨ ^{0}$

M. Ablikim, M. N. Achasov, P. Adlarson +694

The decay $I ¨ (3686) \to I^^{3} I ¨ ^{+} I ¨ ^{-} I ¨ ^{0}$ is studied using a sample of $(2712.4 \pm 14.3) \times 1 0^{6}$ $I ¨ (3686)$ events collected with the BESIII detector. The decay $Î·(1405)\toÏ^+Ï^-Ï…
