The anomalous magnetic moment of the negative muon has been measured to a precision 0.7 ppm (ppm) at Brookhaven Alternating Gradient Synchrotron. This result is based on data collected in 2001, and over an order magnitude more precise than previous measurement for muon. a(mu(-))=11 659 214(8)(3) x 10(-10) (0.7 ppm), where first uncertainty statistical second systematic, consistent with measurements anomaly positive average a(mu)(exp)=11 208(6) (0.5 ppm).
Three independent searches for an electric dipole moment (EDM) of the positive and negative muons have been performed, using spin precession data from muon g-2 storage ring at Brookhaven National Laboratory. Details on experimental apparatus three analyses are presented. Since individual results muon, as well combined result, d=-0.1(0.9)E-19 e-cm, all consistent with zero, we set a new EDM limit, |d| < 1.9E-19 e-cm (95% C.L.). This represents factor 5 improvement over previous best limit EDM.
A higher precision measurement of the anomalous g value, a(mu)=(g-2)/2, for positive muon has been made at Brookhaven Alternating Gradient Synchrotron, based on data collected in year 2000. The result a(mu(+))=11 659 204(7)(5)x10(-10) (0.7 ppm) is good agreement with previous measurements and an error about one-half that combined data. present world average experimental value a(mu)(expt)=11 203(8)x10(-10) ppm).
The TOTEM Experiment will measure the total pp cross-section with luminosity-independent method and study elastic diffractive scattering at LHC. To achieve optimum forward coverage for charged particles emitted by collisions in interaction point IP5, two tracking telescopes, T1 T2, be installed on each side pseudorapidity region 3.1 ⩽ |η| 6.5, Roman Pot stations placed distances of ±147 m ±220 from IP5.

The TOTEM collaboration has measured the proton-proton total cross section at $\sqrt{s}=13$ TeV with a luminosity-independent method. Using dedicated $β^{*}=90$ m beam optics, Roman Pots were inserted very close to beam. inelastic scattering rate been by T1 and T2 telescopes during same LHC fill.

The spin precession frequency of muons stored in the $(g-2)$ storage ring has been analyzed for evidence Lorentz and CPT violation. Two violation signatures were searched for: a nonzero $\Delta\omega_{a}$ (=$\omega_{a}^{\mu^{+}}-\omega_{a}^{\mu^{-}}$); sidereal variation $\omega_{a}^{\mu^{\pm}}$. No significant effect is found, following limits on standard-model extension parameters are obtained: $b_{Z} =-(1.0 \pm 1.1)\times 10^{-23}$ GeV; $(m_{\mu}d_{Z0}+H_{XY}) = (1.8 6.0 \times 10^{-23})$...

Beam collimation in high-energy colliders is customarily carried out by means of massive amorphous absorbers surrounding the circulating beam. Several studies were performed last decades to establish an innovative technique that relies on particle deflection channeling between crystalline planes a bent crystal. We report operational use crystal Large Hadron Collider was achieved during special high-${\ensuremath{\beta}}^{\ensuremath{\ast}}$ physics run with low-intensity beams, representing...
