About elementary particles

open access: yesЛитьë и металлургия, 2023
It is shown that only stable particles can be elementary particles. The fundamental elementary particles are positive, negative and neutral particles of space.

The attenuation of atmospheric Cerenkov photons [PDF]

open access: yes, 2002
Whilst the atmosphere places a limit on the successful applications of many branches of astronomy, it becomes an invaluable tool for the detection of very high energy γ-rays. This thesis is concerned with reducing the systematic uncertainties inherent to

Phase distortions of attosecond pulses produced by resonance-enhanced high harmonic generation

open access: yesNew Journal of Physics, 2013
Resonant enhancement of high harmonic generation can be obtained in plasmas containing ions with strong radiative transitions resonant with harmonic orders. The mechanism for this enhancement is still debated.

Multimode quantum states with single photons carrying orbital angular momentum [PDF]

open access: yes, 2017
We propose and experimentally demonstrate a scheme for generating multimode quantum states with single photons carrying orbital angular momentum (OAM). Various quantum states have been realized by superposing multiple OAM modes of single photons in two ...

Charmonium Production in Photon-Photon Collisions [PDF]

open access: yesPhysical Review Letters, 1988
We have searched for the two-photon production of the /eta//sub c/, /chi//sub 0/ and /chi//sub 2/ charmonium states at the e/sup +/e/sup -/ collider PEP in the channels /gamma//gamma/ /yields/ K/sup +-/K/sub S//sup 0//pi//sup -+/, /gamma//gamma/ /yields/ K/sup +/K/sup -//pi//sup +//pi//sup -/, /gamma//gamma/ /yields/ /pi//sup +//pi//sup -//pi//sup ...

Charge noise and spin noise in a semiconductor quantum device [PDF]

open access: yes, 2014
Self-assembled quantum dots are very attractive as the building blocks for quantum light sources and spin qubits. For instance, a single quantum dot is a robust, fast, narrow-linewidth source of single photons, features not shared by any other ...

Sensitive detection of infrared photons using a high-Q microcantilever [PDF]

open access: yes, 2011
A new approach based on microcantilevers is presented to detect infrared photons with high sensitivity. Infrared photons are measured by monitoring the amplitude change of a vibrating microcantilever under light pressure force.

Photon differentials [PDF]

open access: yesProceedings of the 5th international conference on Computer graphics and interactive techniques in Australia and Southeast Asia, 2007
A number of popular global illumination algorithms uses density estimation to approximate indirect illumination. The density estimate is performed on finite points -- particles -- generated by a stochastic sampling of the scene. In the course of the sampling, particles, representing light, are stochastically emitted from the light sources and reflected

The conversion coefficients from Нр(10) to effective dose in the fields of photon radiation and their use in the development of occupational exposure models

open access: yesРадиационная гигиена, 2023
The paper presents the values of the conversion coefficients from the operational quantity, HP(10)/ to the protection quantity, effective dose (E). The conversion coefficients were calculated in a number of points located at a depth of 10 mm under the ...

Observation of the muon inner bremsstrahlung at LEP1 [PDF]

open access: yes, 2007
Muon bremsstrahlung photons converted in front of the DELPHI main tracker (TPC) in dimuon events at LEP1 were studied in two photon kinematic ranges: 0 ...
