Z-boson as "the standard candle" for high precision W-boson physics at LHC
In this paper we propose a strategy for measuring the inclusive W-boson
production processes at LHC. This strategy exploits simultaneously the unique
flexibility of the LHC collider in running variable beam particle species at
variable beam energies, and the configuration flexibility of the LHC detectors.
We propose their concrete settings for a precision measurement of the Standard
Model parameters. These dedicated settings optimise the use of the Z boson and
Drell-Yan pair production processes as ``the standard reference candles''. The
presented strategy allows to factorise and to directly measure those of the QCD
effects which affect differently the W and Z production processes. It reduces
to a level of 10^{-4} the impact of uncertainties in the partonic distribution
functions (PDFs) and in the transverse momentum of the quarks on the
measurement precision. Last but not the least, it reduces by a factor of 10 an
impact of systematic measurement errors, such as the energy scale and the
measurement resolution, on the W-boson production observables.Comment: 20 pages, 4 figure
Cross Section Ratios between different CM energies at the LHC: opportunities for precision measurements and BSM sensitivity
The staged increase of the LHC beam energy provides a new class of
interesting observables, namely ratios and double ratios of cross sections of
various hard processes. The large degree of correlation of theoretical
systematics in the cross section calculations at different energies leads to
highly precise predictions for such ratios. We present in this letter few
examples of such ratios, and discuss their possible implications, both in terms
of opportunities for precision measurements and in terms of sensitivity to
Beyond the Standard Model dynamics.Comment: 19 pages, 9 figure
Spectroscopy at B-factories Using Hard Photon Emission
The process of hard photon emission by initial electrons (positrons) at
B-factories is discussed. It is shown that studies of the bottomonium
spectroscopy will be feasible for the planned integrated luminosity of the
B-factory experiments.Comment: 9 pages, Latex, 1 fugure, Submitted to Int.Jour.Mod.Phys.
Measurement of MW+ - MW- at LHC
This paper is the second of the series of papers proposing dedicated
strategies for precision measurements of the Standard Model parameters at the
LHC. The common feature of these strategies is their robustness with respect to
the systematic measurement and modeling error sources. Their impact on the
precision of the measured parameters is reduced using dedicated observables and
dedicated measurement procedures which exploit flexibilities of the collider
and detector running modes. In the present paper we focus our attention on the
measurement of the charge asymmetry of the W-boson mass. This measurement is of
primordial importance for the LHC experimental program, both as a direct test
of the charge-sign-independent coupling of the W-bosons to the matter particles
and as a necessary first step towards the precision measurement of the
charge-averaged W-boson mass. We propose and evaluate the LHC-specific strategy
to measure the mass difference between the positively and negatively charged
W-bosons, MW+ - MW-. We show that its present precision can be improved at the
LHC by a factor of 20. We argue that such a precision is beyond the reach of
the standard measurement and calibration methods imported to the LHC from the
Tevatron program.Comment: 39 pages, 8 figure
Tagged-photon events in polarized DIS process
Deep-inelastic events for the scattering of the longitudinally polarized
electron by polarized proton with tagged collinear photon radiated from
initial-state electron are considered. The corresponding cross-section is
derived in the Born approximation. The model-independent radiative corrections
to the Born cross-section are also calculated. Obtained result is applied to
the case of elastic scattering.Comment: 14 pages, 2 figures, submitted to JET

Background. Surgical morbidities of radical cystectomy, which are, as a rule, complicated intraabdominal infections, appear to be the main causes of repeated surgeries and fatal outcomes. The elimination of the infection Indus and an-timicrobic therapy are the currently accepted standard of treatment for postoperative peritonitis in cancer urology, as well as in general surgery hospital.Objective: defining the most reasonable option of surgical aid for peritonitis developing after cystectomy.Materials and methods. In the time period from 2000 through 2014, 58 cancer patients with postoperative peritonitis developing after cystectomy received indoor treatment at N.N. Alexandrov Republican Research and Practical Center for Oncology and Medical Radiology. Their mean age was 64.9 years, the range 44-90 years, 53 (91.4 %) of them being male. Primary urinary bladder cancer was present in 51 (87.9 %) patients. Peritoneal infection was microbiologically verified in 57 (98.3 %) patients. Each case of fatal outcome was associated with ineffective treatment of peritonitis. Depending on the intraoperative findings (presence or absence of a hollow organ defect) and the surgical approach undertaken (obstructive resection or operation maintaining the continuity of the intestinal and/or urinary tract), the patients were stratified into three groups: group 1 (n = 28), group 2 (n = 20) and group 3 (n = 10). There were no significant differences in the basic parameters specifying peritoneal infection severity between the patients of groups 1 and 2 vs group 3 (p >0.05).Results. Overall mortality amounted to 25.9 %, 15 patients died. Among the 28 (48.3 %) patients (group 1) who underwent obstructive elimination of the peritonitis focus by means of urointestinal reservoir ablation, resection of small or large intestine with ileo- or colostomy, 6 patients died, mortality 21.4 %. In the 10 (17.2 %) patients (group 3) who succeeded in preserving the urinary conduit or continuity of the bowels by anastomosis defect closure, resection of enteroentero-anastomosis or urointestinal reservoir with repeated anastomosing or defect closure, mortality was higher (60 %) (p = 0.045); 6 patients died.Conclusion. The most effective option of surgical treatment of postoperative peritonitis developing after cystectomy is obstructive reoperation on the bowels and urinary tracts: compared with the intervention consisting in preserving the urinary conduit and/or continuity of the intestinal tract, this type of surgery caused a 2.8-fold lower mortality.ΠΠ²Π΅Π΄Π΅Π½ΠΈΠ΅.

The impact of different prognostics factors on the probability of development local and systemic relups in patient with biochemical recurrence following prostatectomy was studied. By multivariable analysis, predictors of systemic progression were seminal vesicle invasion (pT3b) (p = 0,005), trigger prostate-specific antigen level greater than 2 ng/mL (p = 0,03), prostate-specific antigen doubling time of 6 months or less (p = 0,002) and prostate-specific antigen velocity greater than 0,1 ng/mL per month (p < 0,0001). The rate of systemic progression in patient with not greater than one unfavorable predictor was 6,3 %, with two or greater predictors β 88,9 % (p < 0,001).ΠΠ·ΡΡΠ°Π»ΠΎΡΡ Π²Π»ΠΈΡΠ½ΠΈΠ΅ ΡΠ°Π·Π»ΠΈΡΠ½ΡΡ

Measurement and application of electron stripping of ultrarelativistic
New measurements of the stripping cross-section for ultrarelativistic
hydrogen-like lead ions passing through aluminium and silicon have been
performed at the Advanced Wakefield experiment at CERN. Agreement with existing
measurements and theory has been obtained. Improvements in terms of electron
beam quality and ion beam diagnostic capability, as well as further
applications of such an electron beam, are discussed
