Center of mass of a system of variable mass particles
Revista Brasileira de Ensino de FísicaWe study the dynamics of the center of mass (CM) of a set of particles when the number of particles in the system varies during a short interval of time, or when the value of the mass of one of the particles depends on time.

Newton’s Second Law of a particle with variable mass [PDF]
Revista Brasileira de Ensino de FísicaWe approach the question of the movement of a particle with variable mass observed from an inertial frame. We consider two different situations: (i) a particle whose intrinsic mass value varies over time; (ii) the center of mass (CM) of a set of ...

On Galilei Invariance in Quantum Mechanics and the Bargmann Superselection Rule [PDF]
, 1995 We reinvestigate Bargmann's superselection rule for the overall mass of $n$ particles in ordinary quantum mechanics with Galilei invariant interaction potential.

Measuring the W-Boson mass at a hadron collider: a study of phase-space singularity methods [PDF]
, 2011 The traditional method to measure the W-Boson mass at a hadron collider (more precisely, its ratio to the Z-mass) utilizes the distributions of three variables in events where the W decays into an electron or a muon: the charged-lepton transverse ...

On a possible approach to the variable-mass problem
, 2002 The mass operator M is introduced as an independent dynamical variable which is taken as the translation generator P_4 of the inhomogenous De Sitter group.

Dynamical Equations, Invariants and Spectrum Generating Algebras of Mechanical Systems with Position-Dependent Mass [PDF]
, 2013 We analyze the dynamical equations obeyed by a classical system with position-dependent mass. It is shown that there is a non-conservative force quadratic in the velocity associated to the variable mass.
