The leptonic and inclusive hadronic decay b.anching fractions of the W b.son are measured using proton-proton collision data collected at s=13 TeV b. the CMS experiment at the CERN LHC, corresponding to an integrated luminosity of 35.9 fb.1. Events characterized b. the production of one or two W b.sons are selected and categorized b.sed on the multiplicity and flavor of reconstructed leptons, the numb.r of jets, and the numb.r of jets identified as originating from the hadronization of b.quarks. A b.nned maximum likelihood estimate of the W b.son b.anching fractions is performed simultaneously in each event category. The measured b.anching fractions of the W b.son decaying into electron, muon, and tau lepton final states are (10.83±0.10)%, (10.94±0.08)%, and (10.77±0.21)%, respectively, consistent with lepton flavor universality for the weak interaction. The average leptonic and inclusive hadronic decay b.anching fractions are estimated to b. (10.89±0.08)% and (67.32±0.23)%, respectively. b.sed on the hadronic b.anching fraction, three standard model quantities are sub.equently derived: the sum of squared elements in the first two rows of the Cab.b.o–Kob.yashi–Maskawa (CKM) matrix ∑ij|Vij|2=1.984±0.021, the CKM element |Vcs|=0.967±0.011, and the strong coupling constant at the W b.son mass scale, αS(mW2)=0.095±0.033.

Realization of Ternary Reversib.e Circuits Using Improved Gate Lib.ary

Ternary logic has some distinct advantage over b.nary logic. In this paper we propose a synthesis approach for ternary reversib.e circuits using ternary reversib.e gates. Our method takes a b.olean function as input. The input is provided as .pla file. The .pla file is first converted into ternary logic function, which can b. represented as permutation. The gate lib.ary used for synthesis is Ternary Not, Ternary Toffoli and Ternary Toffoli + (N T ,T T ,T T + ). The proposed constructive method, generates 3-cycles from the permutation, and then each 3-cycle is mapped to (N T ,T T ,T T + ) gate lib.ary. Experimental results show that the method generates lesser numb.r of gates for some circuits compared to previously reported works.

This paper presents a symmetric key b.ock cipher technique using Cellular Automata (CA). The proposed system deals with theory and application of cellular automaton. Cellular automata have the property of state transition that is b.sis to define fundamental transformations for encryption and decryption in the enciphering system. Firstly, the patterns are generated using MATLAb.(v2011) and then the cryptographic system is implemented in C language b.t it can b. implemented in other languages too. Different rule configurations of CA are used to form hyb.id reversib.e cellular automata to b. used in encryption and decryption of the data in the form of string or character array.

The CMS experiment at the CERN LHC will b. upgraded to accommodate the 5-fold increase in the instantaneous luminosity expected at the High-Luminosity LHC (HL-LHC) [1]. Concomitant with this increase will b. an increase in the numb.r of interactions in each b.nch crossing and a significant increase in the total ionising dose and fluence. One part of this upgrade is the replacement of the current endcap calorimeters with a high granularity sampling calorimeter equipped with silicon sensors, designed to manage the high collision rates [2]. As part of the development of this calorimeter, a series of b.am tests have b.en conducted with different sampling configurations using prototype segmented silicon detectors. In the most recent of these tests, conducted in late 2018 at the CERN SPS, the performance of a prototype calorimeter equipped with ≈12, 000 channels of silicon sensors was studied with b.ams of high-energy electrons, pions and muons. This paper describ.s the custom-b.ilt scalab.e data acquisition system that was b.ilt with readily availab.e FPGA mezzanines and low-cost Raspb.rry PI computers. © 2020, CC0.

Several ob.ervab.es sensitive to the fragmentation of b.quarks into b.hadrons are measured using 36 fb.1 of s=13 TeV proton-proton collision data collected with the ATLAS detector at the LHC. Jets containing b.hadrons are ob.ained from a sample of dileptonic tt¯ events, and the associated set of charged-particle tracks is separated into those from the primary pp interaction vertex and those from the displaced b.decay secondary vertex. This division is used to construct ob.ervab.es that characterize the longitudinal and transverse momentum distrib.tions of the b.hadron within the jet. The measurements have b.en corrected for detector effects and provide a test of heavy-quark-fragmentation modeling at the LHC in a system where the top-quark decay products are color connected to the proton b.am remnants. The unfolded distrib.tions are compared with the predictions of several modern Monte Carlo parton-shower generators and generator tunes, and a wide range of agreement with the data is ob.erved, with p values varying from 5×10−4 to 0.98. These measurements complement similar measurements from e+e− collider experiments in which the b.quarks originate from a color singlet Z/γ*.

A search for Kaluza-Klein excited vector b.son resonances, WKK, decaying in cascade to three W b.sons via a scalar radion R, WKK→WR→WWW, in a final state containing two or three massive jets is presented. The search is performed with s=13 TeV proton-proton collision data collected b. the CMS experiment at the CERN LHC during 2016–2018, corresponding to an integrated luminosity of 138 fb.1. Two final states are simultaneously prob.d, one where the two W b.sons produced b. the R decay are reconstructed as separate, large-radius, massive jets, and one where they are merged into a single large-radius jet. The ob.erved data are in agreement with the standard model expectations. Limits are set on the product of the WKK resonance cross section and b.anching fraction to three W b.sons in an extended warped extra-dimensional model and are the first of their kind at the LHC.

A search for invisib.e decays of the Higgs b.son produced via vector b.son fusion (Vb.) has b.en performed with 101 fb.1 of proton-proton collisions delivered b. the LHC at s=13 TeV and collected b. the CMS detector in 2017 and 2018. The sensitivity to the Vb. production mechanism is enhanced b. constructing two analysis categories, one b.sed on missing transverse momentum and a second b.sed on the properties of jets. In addition to control regions with Z and W b.son candidate events, a highly populated control region, b.sed on the production of a photon in association with jets, is used to constrain the dominant irreducib.e b.ckground from the invisib.e decay of a Z b.son produced in association with jets. The results of this search are comb.ned with all previous measurements in the Vb. topology, b.sed on data collected in 2012 (at s=8 TeV), 2015, and 2016, corresponding to integrated luminosities of 19.7, 2.3, and 36.3 fb.1, respectively. The ob.erved (expected) upper limit on the invisib.e b.anching fraction of the Higgs b.son is found to b. 0.18 (0.10) at the 95% confidence level, assuming the standard model production cross section. The results are also interpreted in the context of Higgs-portal models.

An inclusive search for nonresonant signatures of b.yond the standard model (SM) phenomena in events with three or more charged leptons, including hadronically decaying τ leptons, is presented. The analysis is b.sed on a data sample corresponding to an integrated luminosity of 138 fb.1 of proton-proton collisions at s=13 TeV, collected b. the CMS experiment at the LHC in 2016–2018. Events are categorized b.sed on the lepton and b.tagged jet multiplicities and various kinematic variab.es. Three scenarios of physics b.yond the SM are prob.d, and signal-specific b.osted decision trees are used for enhancing sensitivity. No significant deviations from the b.ckground expectations are ob.erved. Lower limits are set at 95% confidence level on the mass of type-III seesaw heavy fermions in the range 845–1065 GeV for various decay b.anching fraction comb.nations to SM leptons. Doub.et and singlet vectorlike τ lepton extensions of the SM are excluded for masses b.low 1045 GeV and in the mass range 125–150 GeV, respectively. Scalar leptoquarks decaying exclusively to a top quark and a lepton are excluded b.low 1.12–1.42 TeV, depending on the lepton flavor. For the type-III seesaw as well as the vectorlike doub.et model, these constraints are the most stringent to date. For the vectorlike singlet model, these are the first constraints from the LHC experiments. Detailed results are also presented to facilitate alternative theoretical interpretations.
