B lifetime measurements with exclusively reconstructed B decays
Data collected with the BABAR detector at the PEP-II asymmetric B Factory at SLAC are used to study the lifetime of the B0 and B+ mesons. The data sample consists of 7.4 fb-1 collected near the Y(4S) resonance. B0 and B+ mesons are fully reconstructed in

Secondary particle clusterization in carbon-carbon collision
In the present work, using the hadron clustering algorithm, we have determined the mass of π0 mesons with excellent accuracy by restoring data of the neutral particles which are produced in the collisions of carbons and propane.

Magnetic moments and electromagnetic radii of nucleon and $\Delta(1232)$ in an extended GBE model
We derive the exchange currents of pseudoscalar, vector, and scalar mesons from Feynman diagrams, and use them to calculate the magnetic form factors of nucleon and $\Delta(1232)$.

Particle-Particle Particle-Tree: A Direct-Tree Hybrid Scheme for Collisional N-Body Simulations [PDF]
In this paper, we present a new hybrid algorithm for the time integration of collisional N-body systems. In this algorithm, gravitational force between two particles is divided into short-range and long-range terms, using a distance-dependent cutoff ...

New U(1) Gauge Symmetry of Quarks and Leptons
Instead of anchoring the seesaw mechanism with the conventional heavy right-handed neutrino singlet, a small Majorana neutrino mass may be obtained just as well with the addition of a heavy triplet of leptons per family to the minimal standard model of ...

A macroscopic quantum state analysed particle by particle [PDF]
Explaining how microscopic entities collectively produce macroscopic phenomena is a fundamental goal of many-body physics. Theory predicts that large-scale entanglement is responsible for exotic macroscopic phenomena, but observation of entangled ...

Particle Flow Gaussian Particle Filter
State estimation in non-linear models is performed by tracking the posterior distribution recursively. A plethora of algorithms have been proposed for this task. Among them, the Gaussian particle filter uses a weighted set of particles to construct a Gaussian approximation to the posterior.

Mass effect in polarization investigation at BEPC/BES and the B-factory
We consider the annihilation process of an electron-positron pair into a pair of heavier fermions when the initial electron and position beams are polarized.
