Prospects for an experiment to measure BR(KL→π0ννˉ)BR(K_L\rightarrow \pi^0\nu\bar\nu) at the CERN SpS

We are investigating the feasibility of performing a measurement of $BR(K_L\rightarrow\pi^0\nu\bar\nu)$ using a high-energy secondary neutral beam at the CERN SPS in a successor experiment to NA62. The timescale would require many years; we assume that the experiment would be ready at the start of LHC Run 4. Some preliminary conclusions from our feasibility studies, design challenges faced and sensitivity obtainable for the measurement are here presented

The NA62 Experiment at CERN

The main physics goal of the NA62 experiment at CERN is to precisely measure the branching ratio of the kaon rare decay $K^+\rightarrow \pi^+ \nu \bar\nu$. This decay is strongly suppressed in the Standard Model and its branching ratio is theoretically calculated with high accuracy. The NA62 experiment is designed to measure this decay rate with an uncertainty better than 10\%. The measurement can be a good probe of new physics phenomena, which can alter the SM decay rate. The NA62 experiment has been successfully launched in October 2014. In this document, after an introduction to the theoretical framework, the NA62 experimental setup is described and a first look at the pilot run data is reported

Measurement of the τ lepton electric dipole moment at BaBar

The search for a CP violation signature arising from an electric dipole moment of the τ lepton in the e+e− → τ+τ− reaction is currently in progress using 470 fb−1 of data collected with the BaBar detector at the PEP II collider from 1999 to 2008. In this paper the EDM search analysis method will be illustrated

The search for a CP violation signature arising from an electric dipole moment of the τ lepton in the e+e− → τ+τ− reaction is currently in progress using 470 fb−1 of data collected with the BaBar detector at the PEP II collider from 1999 to 2008. In this paper the EDM search method in development will be illustrated and the required algorithms tested on Monte Carlo samples that do not take into account the detector and background effects are shown

Spectrometer for laser-plasma accelerated electrons at PlasmonX at the Frascati National Laboratory

This paper describes the characteristics of the magnetic spectrometer realized for the laser-plasma acceleration experiment PlasmonX at the Frascati National Laboratory. The laser-plasma interaction produces bunches of about 1010 e− with energies spreading over three orders of magnitude from a few MeV to the GeV region

Some Condition for Scalar and Vector Measure Games to Be Lipschitz

We provide a characterization for vector measure gamesν=f∘μinpNA∞, withμvector of nonatomic probability measures, analogous to the one of Tauman for games inpNA, and also provide a necessary and sufficient condition for a particular class of vector measure games to belong toAC∞

Fixed Point Theorems for Middle Point Linear Operators in L1

We introduce the notion of middle point linear operators. We prove a fixed point result for middle point linear operators in L1. We then present some examples and, as an application, we derive a Markov-Kakutani type fixed point result for commuting family of α-nonexpansive and middle point linear operators in L1

The Burkill-Cesari Integral on Spaces of Absolutely Continuous Games

We prove that the Burkill-Cesari integral is a value on a subspace ofACand then discuss its continuity with respect to both theBVand the Lipschitz norm. We provide an example of value on a subspace ofACstrictly containingpNAas well as an existence result of a Lipschitz continuous value, different from Aumann and Shapley's one, on a subspace ofAC∞

Coalitional extreme desirability in finitely additive exchange economies

We define a new notion of extreme desirability for economies in coalitional form. Through this, we obtain a finitely additive core-Walras equivalence theorem for an exchange economy with a measure space of agents and an infinite dimensional commodity space, whose positive cone has possibly empty interior

Stochastic processes and applications to countably additive restrictions of group-valued finitely additive measures

As an application of a theorem concerning a general stochastic process in a finitely additive probability space, the existence of non-atomic countably additive restrictions with large range is obtained for group-valued finitely additive measures
