Search for a Dark Higgs Boson Produced in Asociation with Inelastic Dark Matter at the Belle II Experiment Open
Inelastic dark matter models that have two dark matter particles and a massive dark photon can reproduce the observed relic dark matter density without violating cosmological limits. The mass splitting between the two dark matter particles…

Dark Matter Search Results from of Exposure of the LUX-ZEPLIN (LZ) Experiment Open
We report results of a search for nuclear recoils induced by weakly interacting massive particle (WIMP) dark matter using the LUX-ZEPLIN (LZ) two-phase xenon time projection chamber. This analysis uses a total exposure of 4.2±0.1 tonne-yea…

Search for $B^0 \to K^{\ast 0} τ^+ τ^-$ decays at the Belle II experiment Open
We present a search for the rare flavor-changing neutral-current decay $B^0 \to K^{\ast 0} τ^+ τ^-$ with data collected by the Belle II experiment at the SuperKEKB electron-positron collider. The analysis uses a 365 fb$^{-1}$ data sample r…

Search for Pcs(4459) and Pcs(4338) in Upsilon(1S,2S) inclusive decays at Belle Open
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. Us…

Measurement Of Inclusive Jet Cross-Section In Proton-Proton Collisions At √s = 13TeV Using The CMS Detector At The LHC Open
The theory of Quantum Chromodyanmics (QCD) is one of the fundamental underlying theories to describe interactions among quarks and gluons. In QCD, partons (quarks and gluons) are produced in hadron-hadron collision with large cross-section…
