We present a new strategy for the dispersive evaluation of hadronic light-by-light contribution to anomalous magnetic moment muon $a_\mu$. The approach directly applies in kinematic limit relevant $a_\mu$: one photons is treated as an external electromagnetic field with vanishing momentum, so that kinematics corresponds triangle. derive expressions single-particle intermediate states, well tens...

FOOT (FragmentatiOn Of Target) is an applied nuclear physics experiment that aims at a full characterization of the fragmentation processes interest for Particle Therapy and Radiation Protection in Space. The program foresees set measurements direct inverse kinematics using particle beams targets with composition similar to human tissues spacecraft shielding materials. final goal measurement do...

Classical particle mechanics is developed from the precept that, kinematics and the notion of force aside, power is the most basic ingredient in any mechanical theory. The essential properties of forces between particles are derived by requiring that the net power expended within any subsystem of particles be frame-indifferent. Moreover, requiring that the net power expended on any subsystem of...

To Start: Our goal in this opening section is to define what we mean by ’fluid flow’, a phrase we will use repeatedly, and to consider how a fluid flow is like and unlike solid particle dynamics. A second and more substantial goal is to erect a coordinate system that will be suitable for analyzing fluid flows quantitatively. The definition of a coordinate system is a matter of choice, and the q...

A bstract We propose that the symbol alphabet for classes of planar, dual-conformal-invariant Feynman integrals can be obtained as truncated cluster algebras purely from their kinematics, which correspond to boundaries (compactifications of) G + (4 , n ) /T -particle massless kinematics. For one-, two-, three-mass-easy hexagon kinematics with = 7 8 9, we find finite D 4 5 and 6 respectively, in...

purpose to examine the intra-rater reliability of knee movement data in sagital plane obtained from electrogoniometer (egm) in a basic, sport-specific task of karate. methods a total of 23 elite karate athletes (13 females and 10 males; mean age of 16.10±1.26 yrs) participated in this study. the task was defined as performing three consecutive zenkutsu-dachi in two sessions. the used egm was a ...

objectives: investigating the effect of endurance training program onthe gait pattern of non-active elderly people. methods & materials: this study has been done by a semi-experience method with 23 old men and women by the average and standard deviation of 70/50±6/9 years old (n=14 people of exercise group, n=9 people of control group). the exercise group took part in this program for eight wee...
